Cabinet Design Ensures Water Integrity
Ease of Service, Installation and Maintenance
Mixed Model Build Enables “Fastest in the Industry” Ship Cycle Times
Outstanding Airflow Distribution
ReliaTel Controls Benefits
Rigorous Testing
Unmatched Product Support
Outstanding Standard Features
Anti-Short Cycle Timer
Provides a 3 minute minimum “ON” time and 3 minute “OFF” time for compressors to enhance
compressor reliability by assuring proper oil return.
Colored and Numbered Wiring
Save time and money tracing wires and diagnosing the unit.
Compressors
Trane eFlex™ variable speed scroll compressors
are matched with a specially designed variable
frequency drive that allows a modulating ratio of up
to 4:1. Our eFlex™ compressors are paired with
fixed speed compressors such that the units are
capable of continuous capacity modulation from
10% to 100%. By design, unit combined airflow and
compressor capacities overlap to minimize the
frequent cycling between stages typical of
competing designs. This allows for unmatched
control of leaving air temperatures to meet space
loads.
The eFlex™ compressors also include brushless
permanent magnet motors designed to operate at
higher efficiency along with reducing the
compressor motor speed and cycling results in
significant part load energy savings. This makes
units with eFlex™ compressors the most efficient
products in their class at part load.
Controls—ReliaTel
ReliaTel microprocessor controls provide unit control for heating, cooling and ventilating utilizing
input from sensors that measure indoor and outdoor temperature and other zone sensors. ReliaTel
also provides outputs for building automation systems and expanded diagnostics. For a complete
list of ReliaTel offerings, refer to “Other Benefits,” p. 15.
Conversionless Units
The dedicated design units (either downflow or horizontal) require no panel removal or alteration
time to convert in the field — a major cost savings during installation. Horizontal units come
complete with duct flanges so the contractor doesn’t have to field fabricate them. These duct
flanges are a time and cost saver.
6
RT-PRC056A-EN
Features and Benefits
Crankcase Heaters
These band heaters provide improved compressor reliability by warming the oil to prevent
migration during off-cycles or low ambient conditions. These are standard on all Voyager models.
Discharge Air Temperature Sensor
Provides true discharge air sensing in heating models.
Discharge Line Thermostat
A bi-metal element discharge line thermostats installed as a standard feature on the discharge line
of each system. This standard feature provides extra protection to the compressors against high
discharge temperatures in case of loss of charge, extremely high ambient and other conditions
which could drive the discharge temperature higher.
Easy Access Low Voltage Terminal Board
Foil Faced Insulation
Voyager’s Low Voltage Terminal Board is
external to the electrical control cabinet. It is
extremely easy to locate and attach the
thermostat wire and test operation of all unit
functions. This is another cost and time saving
installation feature.
All panels in the evaporator section of the unit
have cleanable foil-faced insulation. All edges
are either captured or sealed to ensure no
insulation fibers get into the airstream.
Enhanced Dehumidification with eFlex™
Every Ultra High Efficiency unit is equipped with Enhanced Dehumidification, which operates when
connected to a humidity sensor. With Enhanced Dehumidification, the ReliaTel control reduces the
minimum indoor airflow and modulates the eFlex compressor operation to allow for additional
moisture removal of the return air. When dehumidification is required without cooling, the ReliaTel
control brings the compressors to an appropriate capacity to remove moisture without overcooling
the space providing efficient humidity control.
Frostat™
This capillary bulb embedded in the face of the evaporator coil monitors coil temperature to
prevent evaporator icing and protect the compressor. Recommended for applications with low
leaving air temperatures, low airflow and/or high latent load applications.
Heat Exchanger—Drum and Tube
The cabinet features a drum and tube heat
exchanger (pictured right) that is
manufactured using aluminized steel with
stainless steel components for maximum
durability.
The requirement for cycle testing of heat
exchangers is 10,000 cycles by ANSI Z21.47.
This is the standard required by both UL and
AGA for cycle test requirements.
RT-PRC056A-EN
Forced Combustion Blower
Negative Pressure Gas Valve
Hot Surface Ignitor
7
Features and Benefits
Trane requires the design to be tested to 2½ times this current standard. The drum and tube design
has been tested and passed over 150,000 cycles, which is over 15 times the current ANSI cycling
requirements. The negative pressure gas valve is used in the standard furnaces. This is one of our
unique safety features. Modulating heaters use a pressure switch to ensure that the blower motor
is operating before the gas valve is allowed to open.
The forced combustion blower supplies pre-mixed fuel through a single stainless steel burner
screen into a sealed drum where ignition takes place. It is more reliable to operate and maintain
than a multiple burner system. Modulating furnaces contain a metal fiber material to ensure proper
flame distribution at low fire. The hot surface ignitor is a gas ignition device which doubles as a
safety device utilizing a continuous test to prove the flame. The design is cycle tested at the factory
for quality and reliability. Our gas/electric rooftops exceed all California seasonal efficiency
requirements and perform even better than the California NOx emission requirements.
Low Ambient Cooling
All Voyager microprocessor units have cooling capabilities down to 0°F as standard.
Low Voltage Connections
The wiring of the low voltage connections to the unit and
the zone sensors is as simple as 1-1, 2-2, and 3-3. This
simplified system makes it easy for the installer to wire.
Microchannel Condenser Coil
Microchannel Flat Tube
Header
(top removed)
Ribbon Fin
Microchannel coils have better heat transfer
performance due to flat streamlined tubes with
small ports, and metallurgical tube-to-fin bond.
Microchannel condenser coil can reduce system
refrigerant charge by up to 50% (potential LEED
credit) because of smaller internal volume, which
can lead to better compressor reliability. Compact
all aluminum microchannel coils also help to reduce
the unit weight. All-aluminum construction
improves re-cyclability. Galvanic corrosion is also
minimized due to all aluminum construction. Strong
aluminum brazed structure provides better fin
protection.
Motors
All indoor fan motors are belt drive as standard.
Pressure Cutouts
Low and high pressure cutouts are standard on all Voyager models.
Phase Monitor
Voyager features a three-phase line monitor module that protects against phase loss, phase
reversal and phase unbalance. It is intended to protect compressors from reverse rotation. It has
an operating input voltage range of 190–600 Vac, and LED indicators for ON and FAULT. There are
no field adjustments and the module will automatically reset from a fault condition.

RT-PRC056A-EN
Features and Benefits
Quick-Access Panels
Remove three or more screws for access to the
standardized internal components and wiring.
Quick-Adjust Slider Plate
With the Quick-Adjust Slider Plate (pictured right), the
belt and sheaves can be quickly adjusted without
moving the mounted fan motor. The result is a major
savings in time and money.
ReliaTel Options Module (RTOM)
The RTOM monitors the supply fan proving, clogged
filter, supply air temperature, exhaust fan setpoint,
dehumidification setpoint, supply air tempering,
frostat™ and smoke detector.
Single Point Power
A single electrical connection powers the unit.
Single Side Service
Single side service is standard on all units.
Single Zone VAV - One Zone Variable Air Volume Mode
Note: Single Zone VAV is designed to be used with a zone sensor. If a unit is configured for Single
Zone VAV operation but is connected to a thermostat, the control will revert to multi-speed
(2-Speed) indoor fan control and staged compressor control. This drastically reduces the
energy savings available with this design.
Single zone VAV is designed for use in single zone applications like gymnasiums, auditoriums,
manufacturing facilities, retail box stores, and any large open spaces, where there is a lot of
diversity in the load profile. Single Zone VAV (SZ VAV) is an ideal replacement to "yesterday's"
constant volume (CV) systems, by reducing operating costs while improving occupant comfort.
SZ VAV systems combine Trane application, control and system integration knowledge to exactly
match fan speed with cooling and heating loads, regardless of the operating condition. Trane
algorithms meet/exceed ASHRAE 90.1- 2010, SZ VAV energy-saving recommendations, and those
of CA Title 24. The result is an optimized balance between zone temperature control and system
energy savings. Depending on your specific application, energy savings can be as much as 20%.
Note: Building system modeling in energy simulation software like TRACE is recommended to
evaluate performance improvements for your application.
SZ VAV is fully integrated into the ReliaTel Control system and is available today. It provides the
simplest and fastest commissioning in the industry through proven factory-installed, wired, and
tested system controllers. All control modules, logic and sensors are factory installed, and tested
to assure the highest quality and most reliable system available. This means no special
programming of algorithms, or hunting at the jobsite for sensors, boards, etc. that need to be
installed in the field. Single zone VAV is a quick and simple solution for many applications and is
available from your most trusted rooftop VAV system solution provider - Trane.
Sloped Drain Pans
Every Voyager unit has a non-corrosive, sloped drain pan made of pre-painted steel and standard
on all units.
RT-PRC056A-EN

Features and Benefits
Standardized Components
Components are placed in the same location on all Voyager units. Familiarize yourself with one
Voyager and you are familiar with every Voyager. Due to standardized components throughout the
Voyager line, contractors/owners can stock fewer parts.
Thermal Expansion Valve
Thermal expansion valves are standard on ultra high efficiency units to allow superior control over
full modulating operating range.
U-Shaped Airflow Pattern
The U-shaped airflow allows for improved static capabilities.
Variable Frequency Drives
Variable Frequency Drives are factory installed and tested to provide supply fan motor speed
modulation, as well as modulating gas heat. VFDs on the supply fan, as compared to inlet guide
vanes or discharge dampers, are quieter, more efficient, and are eligible for utility rebates. All VFDs
are designed to allow bypass if required. Bypass control will simply provide full nominal airflow
in the event of drive failure. Modulating gas heat models with VFDs allow tighter space temperature
control with less temperature swing.

either factory or field-installed for condenser coil protection. This
option protects the condenser coil from vandalism and/or hail
damage.
Field Installed Options
CO2 Sensor - Demand Control Ventilation (DCV)
Demand-controlled ventilation (DCV) is a control strategy that responds to the actual demand
(need) for ventilation by regulating the rate at which the HVAC system brings outdoor air into the
building. A CO2 sensor measures the concentration (parts per million, ppm) of CO2 (Carbon
Dioxide) in the air. As the CO2 concentration changes, the outside air damper modulates to meet
the current ventilation needs of the zone. The CO2 sensor kit is available as a field installed
accessory. Two field installed kits are offered; C02 sensor and wiring or C02 sensor only. The C02
sensor only kit should be ordered with factory installed C02 sensor wiring. Factory installed C02
sensor wiring saves set-up time and ensures proper unit connections for the C02 sensor.
Digital Display Zone Sensor
The Digital LCD (Liquid Crystal Display) zone sensor has the look and functionality of standard zone
sensors.
Economizer - Standard, Horizontal
Economizers are equipped with either dry bulb or reference or comparative enthalpy sensing.
These economizers provide free cooling as the outdoor temperature and/or humidity decreases.
Correctly installed, they offer a valuable energy savings.
Economizer - Low Leak, Downflow
This accessory meets low leak requirements for ASHRAE 90.1, IECC, and CA Title 24 standards (3
cfm/ft^2@1" wg exterior air, 4 cfm/ft^2@1" wg return air). This option allows 100% outdoor air
supply from 0-100% modulating dampers and is standard with barometric relief. It can be paired
with powered exhaust for additional building pressure relief. Available on downflow units only.

14
RT-PRC056A-EN
Features and Benefits
LP Conversion Kit
Provided for field conversion of gas/electric units from natural gas to propane.
Powered Exhaust
This option is available on downflow units and provides exhaust of the return air, when using a
downflow economizer, to maintain proper building pressurization. Great for relieving most
building overpressurization problems.
Remote Potentiometer
When properly installed in the economizer control circuitry, this accessory provides a remote
variable resistance to enable the operator to adjust the minimum damper position.
Roof Curbs
Available for downflow units. Only two roof curbs for the entire Voyager line simplifies curb
selection.
Static Drive Accessories
Available on many models, this high and low static drive accessories extend the capability of the
standard motor. Avoid expensive motors and operating costs by installing this optimized sheave
accessory.
Trane Communication Interface (TCI)

Trane’s Integrated Comfort™ System.
Ventilation Override Accessory
With the Ventilation Override Accessory installed, the unit can be set to transition to up to 3 different
pre-programmed sequences for Smoke Purge, Pressurization and Exhaust. The transition occurs
when a binary input on the RTOM is closed (shorted). This would typically be a hard wired relay
output from a smoke detector or fire control panel. The ventilation override kit is available as a field
installed accessory.
Wireless Zone Sensor
LCD display that provides heat, cool, auto, or off. Includes two temperature setpoints and a lockable
setting with °F or °C indicators.
Zone Sensors
Available in programmable, automatic and manual styles.
Note: Zone sensors are required for units configured for Single Zone VAV indoor fan and eFlex
compressor system control to enable Single Zone VAV and eFlex modulation functionality.
Other Benefits
Cabinet Integrity
For added water integrity, Voyager has a raised 1-1/8” lip around the supply and return of the
downflow units to prevent water from blowing into the ductwork.
Easy to Install, Service and Maintain
Because today’s owners are very cost-conscious when it comes to service and maintenance,
Voyager was designed with direct input from service contractors. This valuable information helped
to design a product that would get the serviceman off the job quicker and save the owner money.
Voyager does this by offering outstanding standard features enhanced by a variety of factory and
RT-PRC056A-EN
15
Features and Benefits
field installed options, multiple control options, rigorously tested proven designs and superior
product and technical support.
Outstanding Airflow Distribution
Airflow is outstanding. The Voyager can replace an older machine with old ductwork and, in many
cases, improve the comfort through better air distribution.
ReliaTel™ Controls Benefits
ReliaTel controls provide unit control for heating, cooling
and ventilating by utilizing input from sensors that
measure outdoor and indoor temperature.
Quality and Reliability are enhanced through ReliaTel
control and logic:
– Prevents the unit from short cycling, considerably
improving compressor life.
– Ensures the compressor will run for a specific
amount of time which allows oil to return for better
lubrication, enhancing the reliability of the
compressor.
Voyager with ReliaTel reduces the number of components required to operate the unit, thereby
reducing possibilities for component failure.
ReliaTel Makes Installing and Servicing Easy
ReliaTel eliminates the need for field installed anti-shortcycle timer and time delay relays.
ReliaTel controls provide these functions as an integral part of the unit. The contractor no longer
has to purchase these controls as options and pay to install them. The wiring of the low voltage
connections to the unit and the zone sensors is as easy as 1-1, 2-2, and 3-3. This simplified system
makes wiring easier for the installer.
ReliaTel Makes Testing Easy
ReliaTel requires no special tools to run Voyager unit through its paces. Simply place a jumper
between Test 1 and Test 2 terminals on the Low Voltage Terminal Board and the unit will walk
through its operational steps automatically.
The unit automatically returns control to the zone sensor after stepping through the test mode a
single time, even if the jumper is left on the unit.
As long as the unit has power and the “system on” LED is lit, ReliaTel is operational. The light
indicates that the controls are functioning properly.
ReliaTel features expanded diagnostic capabilities when utilized with Trane Integrated Comfort™
Systems.
Some zone sensor options have central control panel lights which indicate the mode the unit is in
and possible diagnostic information (dirty filters for example).
Other ReliaTel Benefits
The ReliaTel built-in anti-shortcycle timer, time delay relay and minimum “on” time control
functions are factory tested to assure proper operation. ReliaTel softens electrical “spikes” by
staging on fans, compressors and heaters. Intelligent Fallback is a benefit to the building occupant.
If a component goes astray, the unit will continue to operate at predetermined temperature
setpoint.
Intelligent Anticipation is a standard ReliaTel feature. It functions continuously as ReliaTel and zone
sensor(s) work together in harmony to provide much tighter comfort control than conventional
electro-mechanical thermostats.
16
RT-PRC056A-EN
Features and Benefits
The same ReliaTel Board fits all Packaged Gas/Electric, Cooling, and Heat Pump models. This
provides standardization of parts for contractors. Less money is tied up in inventory with ReliaTel.
Rigorous Testing
All of Voyager’s designs were rigorously rain tested at the factory to ensure water integrity. Voyager
units incorporate the Trane-Tite-Top (T3). Each part of the top (either two or three pieces) overlaps
in such a way that water cannot leak into the unit. These overlapped edges are gasketed and sealed
to ensure superior water integrity.
Actual shipping tests were performed to determine packaging requirements. Units were test
shipped around the country to determine the best packaging. Factory shake and drop tests were
used as part of the package design process to help assure that the unit arrives at the job site in top
condition.
Rigging tests include lifting a unit into the air and letting it drop one foot, assuring that the lifting
lugs and rails hold up under stress. For the microchannel coils, the supplier will perform the leak
check at 450 psig. The completely assembled refrigerant system is leak tested at a minimum of
225 psig with a refrigerant and nitrogen mixture.
All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected
immediately. Every unit receives a 100% unit run test before leaving the production line to make
sure it lives up to rigorous Trane requirements.

Application Considerations
Application of this product should be within the cataloged airflow and cooling considerations.
Barometric Relief
This product line offers an optional barometric relief damper for use in conjunction with
economizer option. This accessory consists of gravity dampers which open with increased
pressure. As the building air pressure increases, the pressure in the unit return air section also
increases, opening the dampers and relieving the conditioned space.
Notes:
•
The effectiveness of barometric relief damper during economizing operation is system related.
•
Pressure drop of the return air system should be considered to control building pressurization.
Clearance Requirements
The recommended clearances identified with unit dimensions should be maintained to ensure
adequate serviceability, maximum capacity and peak operating efficiency. Actual clearances which
appear inadequate should be reviewed with local Trane sales personnel.
Complete Coat™ Microchannel Condenser Coil
The cathodic epoxy type electrodisposition coating is formulated for high edge build to a number
of different types of heat exchangers. The coating is selected to provide excellent resistance and
durability to corrosive effects of alkalies, acids, alcohols, petroleum, seawater, salt air, and
corrosive environments. This coating shall be available on microchannel condenser coils.
Condensate Trap
The evaporator is a draw-through configuration. A trap must be field provided prior to start-up on
the cooling cycle.
Heating Operation
The heat exchanger is manufactured with aluminized steel. To prevent condensation within the
heat exchanger, do not exceed 50 percent outside air or a minimum mixed air temperature of 40°F.
Optional Stainless Steel Heat Exchanger
The optional stainless steel heat exchanger is manufactured with 304 stainless steel. To prevent
corrosion and prolong heat exchanger reliability, the minimum mixed air temperature allowed
across the heat exchanger is 20°F. The stainless steel heat exchanger option is an excellent option
that compliments the dehumidification package and is used in conjunction with the modulating
heat option. Whenever high outside air or outside applications exist, these options should be
utilized.
Low Ambient Cooling
The Voyager line features, with ReliaTel™ microprocessor controls, low ambient cooling down to
0°F. The following options need to be included/considered when low ambient applications are
required: continuous fan operation, crankcase heaters (standard), thermal expansion valves,
frostat. Contact your local Trane Representative for more assistance with low ambient cooling
applications.
Unit Pitch
These units have sloped condensate drain pans. Units must be installed level. Any unit slope must
be toward access side of the unit.
Low Airflow
Unit applications designed for airflow below 320cfm/ton are not available on units with eFlex™ and
Single Zone VAV. Voyager units will operate below 320 cfm/ton during normal operation. Units
should not be set below 320 cfm/ton.
18
RT-PRC056A-EN
Application Considerations
Sequence of Operation
ReliaTel Controls
•
The master module is the ReliaTel Refrigeration Module (RTRM).
•
The RTRM provides compressor anti-short cycle timing functions through minimum "Off" and
"On" timing to increase reliability, performance and to maximize unit efficiency.
•
Upon power initialization, the RTRM performs self-diagnostic checks to insure that all internal
controls are functioning. It checks the configuration parameters against the components
connected to the system.
•
The LED located on the RTRM module is turned "On" within one second after power-up if all
internal operations are okay.
•
The RTRM in conjunction with the Variable Speed Module (VSM) will provide capability to
control of a modulating eFlex™ compressor, and two multispeed outdoor motors (ODM).
•
The ReliaTel Options Module (RTOM) is utilized in conjunction with the RTRM for control of a
variable speed indoor motor (IDM) and optional accessories.
•
All units employ a Phase Monitor to ensure proper power supply connection of phases for
compressor operation. If the monitor senses incorrect phase connection (phase reversal), a loss
of phase, or large voltage imbalance between phases, all unit operation will be prevented until
the condition is corrected. The Phase Monitor has green (Ok) and red (Phase Fault) status LEDs
on the face of the monitor. All units are functional tested to ensure correct factory wiring. A red
status LED is an indication of a serious problem that can only be resolved by isolating and
repairing the Supply Power fault.
ReliaTel Control Cooling without an Economizer
When the system switch is set to the "Cool" position and the zone temperature rises above the
cooling setpoint controlband, the RTRM energizes the modulating eFlex compressor starting with
the minimum compressor motor speed and runs through a start-up sequence for that compressor,
provided the low pressure control (LPC4), high pressure control (HPC3), and the discharge line
thermostat (DLT3) are closed. When the eFlex compressor and the outdoor fan motor are
energized, they adjust motor speeds in order to maintain the zone temperature to within ±2°F of
the sensor setpoint at the sensed location. If the modulating compressor at its maximum capacity
cannot satisfy the cooling requirement, the RTRM energizes the first fixed speed compressor,
provided the low pressure control (LPC1), the high pressure control (HPC1), and the discharge line
thermostat (DLT1) are closed, while simultaneously reducing the modulating compressor motor
speed to allow a smooth transition in system capacity. When the fixed speed compressor is
energized, the ReliaTel control starts to maintain the zone temperature to within ±2°F of the sensor
setpoint at the sensed location by modulating the eFlex compressor speed and both ODM. If the
first two compressors cannot satisfy the load, the second fixed speed compressor is energized in
addition to the first fixed speed compressor, provided the low pressure control (LPC1), the high
pressure control (HPC2), and the discharge line thermostat (DLT2) are closed. Simultaneously, the
modulating compressor speed is reduced for a smooth transition to the higher system capacity.
When the third compressor is energized, the ReliaTel control starts to maintain the zone
temperature to within +/-2°F of the sensor setpoint at the sensed location by modulating the eFlex
compressor motor speed and both ODM.
ReliaTel Control Evaporator Fan Operation
With the indoor fan in "Auto" mode, the RTRM energizes the indoor fan motor for approximately
1 second after energizing the modulating compressor in the cooling mode. In the heating mode,
the RTRM energizes the indoor fan motor approximately 45 seconds after gas ignition (gas heat
unit) or 1 second before energizing electric heat (electric heat unit). With the indoor fan in "On"
mode, the RTRM keeps the indoor fan energized for continuous fan motor operation. When the unit
is equipped with the optional clogged filter switch, wired to the ReliaTel Options Module (RTOM),
RT-PRC056A-EN
19
Application Considerations
the RTRM produces an analog signal output if the clogged filter switch closes for two minutes after
a request for fan operation. When the system is connected to a remote panel, the "SERVICE" LED
will be turned on when this failure occurs.
Drain Pan Condensate Overflow Switch (Optional)
This input incorporates the Condensate Overflow Switch (COF) mounted on the drain pan and the
ReliaTel Options Module (RTOM). When the condensate level reaches the trip point for 6 continuous
seconds, the RTOM will shut down all unit function until the overflow condition has cleared. The
unit will return to normal operation after 6 continuous seconds with the COF in a non-tripped
condition. If the condensate level causes the unit to shutdown more than 2 times in a 3 day period,
the unit will be locked-out of operation. A manual reset of the diagnostic system through the Zone
Sensor or Building Automation System will be required. Cycling unit power will also clear the fault.
Low Ambient Operation
During low ambient operation, outside air temperature below 40°F, the RTRM will cycle the
compressors and outdoor fan motors "Off" for approximately 3 minutes after every 10 minutes of
accumulated compressor run time. The indoor fan motor will continue to operate during this
evaporator defrost cycle and the compressors and outdoor fans will return to normal operation
once the defrost cycle has terminated and the compressor "Off" time delay has been satisfied.
ReliaTel Control Cooling with an Economizer
The economizer is utilized to control the zone temperature providing the outside air conditions are
suitable. Outside air is drawn into the unit through modulating dampers. When cooling is required
and economizing is possible, the RTRM sends the cooling request to the unit economizer actuator
to open the economizer damper.
The RTRM tries to cool the zone utilizing the economizer to slightly below the zone temperature
setpoint. If the mixed air sensor (MAS) senses that the mixed air temperature is below 53°F, the
damper modulates toward the closed position.
If the zone temperature continues to rise above the zone temperature setpoint controlband and the
economizer damper is fully open, the RTRM energizes the modulating eFlex compressor. If the zone
temperature continues to rise above the zone temperature setpoint controlband and the
economizer damper is fully open, the RTRM instructs the compressor inverter drive to increase the
compressor speed to allow more compressor capacity.
If the eFlex compressor is running at its maximum capacity and the zone temperature continues
to rise above the zone temperature setpoint controlband and the economizer damper is fully open,
the RTRM energizes the first fixed speed compressor, while simultaneously instructing the
compressor inverter drive to decrease the eFlex compressor capacity to allow a smooth system
capacity transition. If the zone temperature continues to rise above the zone temperature setpoint
controlband and the economizer damper is fully open, the RTRM instructs the compressor inverter
drive to increase the eFlex compressor speed to allow more compressor capacity.
If the eFlex compressor is running at its maximum capacity and the zone temperature continues
to rise above the zone temperature setpoint controlband and the economizer damper is fully open,
the RTRM energizes the second fixed speed compressor, while simultaneously decreasing the
eFlex compressor speed to allow a smooth transition of system cooling capacity.
All compressor capacity transitions are accompanied by corresponding IDM and ODM speed
adjustments to allow optimal unit cooling performance. The ECA continues to modulate the
economizer damper open/closed to keep the mixed air temperature that is calculated by the RTRM.
If economizing is not possible, the ECA drives the damper to the minimum position setpoint when
the indoor fan relay is energized and allows mechanical cooling operation. When the unit is
equipped with the optional fan failure switch, wired to the RTOM, the RTRM will stop all cooling
functions and produce an analog output if the fan failure switch does not open within 40 seconds
after a request for fan operation. When the system is connected to a remote panel, the "SERVICE"
LED will flash when this failure occurs.
20
RT-PRC056A-EN
Application Considerations
Economizer Set-Up
Adjusting the minimum position potentiometer located on the unit economizer actuator (ECA) sets
the required amount of ventilation air.
Two of the three methods for determining the suitability of the outside air can be selected utilizing
the enthalpy potentiometer on the ECA, as described below:
1. Ambient Temperature-Controlling the economizing cycle by sensing the outside air dry bulb
temperature. Table 1 lists the selectable dry bulb values by potentiometer setting.
2. Reference Enthalpy-Controlling the economizer cycle by sensing the outdoor air humidity.
Table 1 lists the selectable enthalpy values by potentiometer setting. If the outside air enthalpy
value is less than the selected value, the economizer is allowed to operate.
3. Comparative Enthalpy-By utilizing a humidity sensor and a temperature sensor in both the
return air stream and the outdoor air stream, the unit control processor (RTRM) will be able to
establish which conditions are best suited for maintaining the zone temperature, i.e. indoor
conditions or outdoor conditions.
The potentiometer located on the ECA is non-functional when both the temperature and humidity
sensors are installed.

ReliaTel Control Heating Operation for Cooling Only Units
When the system switch is set to the "Heat" position and the zone temperature falls below the
heating setpoint controlband, the RTRM energizes the first stage of electric heat. If the first stage
of electric heat cannot satisfy the heating requirement, the RTRM energizes the second stage
electric heat if applicable. The RTRM cycles both the first and second stages of heat "On" and "Off"
as required to maintain the zone temperature setpoint.
ReliaTel Control Heating Operation for Gas Units
When the system switch is set to the "Heat" position and the zone temperature falls below the
heating setpoint controlband, a heat cycle is initiated when the RTRM communicates ignition
information to the Ignition module.
Modulating Gas Heat 2.5:1 Turndown
In a modulating heat unit, when a call for heat is received, the burner will light at full fire (100%).
After the burner is lit, the unit controls will monitor the discharge air temperature and modulate
the input rate down to match the load.
Ignition Control Module
Two-Stage (IGN) runs self-check (including verification that the gas valve is de-energized). IGN
checks the high-limit switches (TC01 and TC02) for normally closed contacts. With power supplied
to the ignition module, the hot surface ignition probe is preheated. The gas valve is energized for
a few seconds for trial for ignition, to ignite the burner. Once the burner is ignited, the hot surface
ignition probe is de-energized by the ignition module and functions as the flame sensing device.
RT-PRC056A-EN
21
Application Considerations
If the burner fails to ignite, the ignition module will attempt two retries before locking out. The green
LED will indicate a lockout by two fast flashes. An ignition lockout can be reset by:
1. Opening for 3 seconds and closing the main power disconnect switch.
2. By switching the "Mode" switch on the zone sensor to "OFF" and then to the desired position.
3. Allowing the ignition control module to reset automatically after one hour. Refer to Table 2 for
the LED diagnostic definitions.
When the fan selection switch is set to the "Auto" position, the RTRM energizes the indoor fan relay
coil approximately 30 seconds after initiating the heating cycle to start the indoor fan motor. The
automatic reset high limit, located in the bottom right corner of the burner compartment, protects
against abnormally high leaving air temperatures. The automatic reset fan fail limit, located in the
upper middle section of the indoor fan board, protects against abnormally high heat buildup which
could occur because of extended cycling of the high limit or if the indoor fan motor fails to operate.
Should TCO2 open, the RTRM will energize the indoor fan relay in an attempt to start the fan motor.
The RTRM signals that a heat failure has occurred by flashing the "Heat" LED on the zone sensor.
There is a green LED located in the Ignition Control Module. Table 2 lists the diagnostics and the
status of the LED during the various operating states.
Ignition Control Module Diagnostics
At any time the control is powered, a green LED indicator light shall be lit using the following signal:

Additionally, the LED indicator light shall flash for one second at power-up.
Enhanced Dehumidification
Enhanced Dehumidification will be available on all units equipped with a Space Humidity sensor.
Once the Space Humidity value exceeds the Dehumidification Setpoint and dehumidification is
enabled the unit will transition to the Enhanced Dehumidification mode. If the unit is actively
cooling, the ReliaTel control will latch the current compressor operation and reduce the current
indoor airflow. If the unit is not actively cooling when the Enhanced Dehumidification mode is
activated, the unit will energize a single fixed speed compressor and the modulating eFlex
compressor will ramp to a fixed speed while engaging the IDM and both ODM at the appropriate
airflow for that condition. If during active enhanced dehumidification the Space Humidity falls
below the Dehumidification Setpoint – 2%, Dehumidification will be terminated and the unit will
transition back to normal Cooling or Heating control.
22
RT-PRC056A-EN
Application Considerations
Single Zone Variable Air Volume (Single Zone VAV) Control
For normal Cooling operation, available cooling capacity will be modulated in order to meet the
calculated discharge air setpoint between the user selected upper and lower limits. If the current
active cooling capacity is controlling the discharge air within the deadband no additional Cooling
capacity change will be requested. As the Discharge Air Temperature rises above the deadband the
control will request additional capacity as required (additional compressor operation or
economizer). As the Discharge Air Temperature falls below the deadband the algorithm will request
a reduction in active capacity.
Cooling Operation
If the control determines that there is a need for compressor operation in order to meet the
discharge air requirements, once supply fan proving has been made, the unit will begin to
modulate compressors. As the zone cooling demand continues to increase, if additional capacity
is required, the supply fan output will be modulated above minimum speed in order to meet the
zone requirements.
Note: The supply fan speed will remain at the activated compressors’ associated minimum value
until the control requires additional capacity to meet the zone demand.
As the cooling load in the zone decreases the control will reduce the speed of the fan down to
minimum per compressor operation and control the compressor outputs accordingly. As the
compressors begin to de-energize, the Supply Fan speed will fall back to the Cooling Capacity's
associated minimum fan speed but not below. As the load in the zone continues to drop, cooling
capacity will be reduced in order to maintain the calculated discharge air setpoint.
Economizer Cooling
During normal Economizer Cooling, the fan speed will operate at its minimum. However, if the
economizer is able to meet the demand alone, due to desirable ambient conditions, the supply fan
speed will be allowed to increase above the minimum prior to utilizing mechanical cooling. Note
that Economizer Enable/Disable decisions will be made based on the previous sections; however,
the economizer control point will now be variable based on the zone cooling demand.
Demand Controlled Ventilation
Units configured for SZVAV and Demand Controlled Ventilation (CO2 sensor value available)
require a new control scheme comprised of 2 existing schemes that have been traditionally
mutually exclusive; DCV and OA CFM Compensation. Units configured with DCV will invoke the
new Demand Controlled Ventilation scheme which allows variable Bldg. Design and DCV Minimum
Positions and OA Damper Position Target setpoints based on the supply fan speed and space CO2
requirements.
Economizer Damper Position Set-Up with DCV
This new scheme will require the setting of 5 OA Damper position setpoints; 3 more than on nonSZ VAV. These new setpoints are located on the RTVM module:
1. Design Min Position @ Minimum Fan Speed Command (RTVM R130)
2. Design Min Position @ Middle Fan Speed Command (RTVM R136)
3. Design Min Position @ Full Fan Speed Command (RTEM Design Min Position)
4. DCV Min Position @ Minimum Fan Speed Command (RTVM R41)
5. DCV Min position @ Full Fan Speed Command (RTEM DCV Min Position)
As the supply fan speed command varies between minimum and maximum, the Building Design
and DCV Minimum Position Targets will be calculated between the user selected setpoints based
on the instantaneous supply fan speed. The Bldg. Design and DCV Minimum Position Targets will
be used to calculate the Active OA Damper Minimum Position Target, as on traditional units, based
on the Space CO2 relative to the active Design and DCV CO2 setpoints.
RT-PRC056A-EN
23
Application Considerations
By default, the Design Minimum Position schedule will be a linear line through all user selectable
Design Minimum Position setpoints. The user will have the ability to set the Design Minimum
Position at Middle fan speed command to a point that would be lower than the calculated linear
line between the Design Minimum Position setpoints at 0% and 100% fan speed command in order
to compensate for the non-linear outside airflow through the fan and damper modulation range.
However, if the Design Minimum Position at Middle fan speed command is set to a point that would
be higher than the calculated linear line between the Design Minimum Position setpoints at
Minimum and Full fan speed command, the minimum position will be limited to the point that
would make the Design Minimum Position schedule linear.
Provisions have been made in Service Test Mode to allow for proper damper minimum position
setup:
1. To set the Design and DCV Minimum Position setpoints at Minimum Fan Speed, set the unit to
operate at Step 1 (Fan ON) or Step 2 (Economizer Open) and make the proper adjustments.
2. To set the Design Minimum Position setpoint at Middle Fan Speed, set the unit to operate at Step
3 (Cool 1) and make the proper adjustment.
3. To set the Design and DCV Minimum Position setpoints at Full Fan Speed, set the unit to operate
at Step 4 (Cool 2) and make the proper adjustments.
Economizer Damper Position Set-Up without DCV
For units not configured with DCV (no CO2 sensor value available), additional minimum position
setpoints to increase outdoor airflow accuracy will be supported. The operation will be similar to
OA CFM Compensation on Traditional VAV units with the addition of a Design Minimum Position
setpoint at Middle Fan Speed Command. The following setpoint potentiometers will be used on
the RTEM:
1. Design Min at Minimum Fan Speed Command (RTEM DCV Min)
2. Design Min at Middle Fan Speed Command (RTEM DCV Setpoint LL)
3. Design Min at Full Fan Speed Command (RTEM Design Min)
The controller will calculate the active OA Damper Minimum position between the user-selected
setpoints based on the supply fan speed command. By Default, the Design Minimum Position
schedule will be a linear line through all user selectable Design Minimum Position setpoints. As
with Demand Controlled Ventilation, if the Design Minimum Position at Middle fan speed
command is set to a point that would be higher than the calculated linear line between the Design
Minimum Position setpoints at Minimum and Maximum fan speed command, the minimum
position will be limited to the point that would make the Design Minimum Position schedule linear.
Provisions have been made in Service Test Mode to allow for proper damper minimum position
setup:
1. To set the Design Minimum Position setpoint at Minimum Fan Speed, set the unit to operate
at Step 1 (Fan ON) or Step 2 (Economizer Open) and make the proper adjustment.
2. To set the Design Minimum Position setpoint at Middle Fan Speed, set the unit to operate at Step
3 (Cool 1) and make the proper adjustment.
3. To set the Design Minimum Position setpoint at Full Fan Speed, set the unit to operate at Step
4 (Cool 2) and make the proper adjustment.
Heating Operation
Heating operation on units configured with Single Zone VAV control will utilize two separate
control methodologies based on heating configurations. For all "Staged" Heating types (Electric
and Gas), the unit will utilize 100% full airflow during all active heating periods like traditional
Constant Volume units. For Modulating Gas heat units, the unit will have the ability to control the
discharge air temperature to the calculated discharge air heating setpoint in order to maintain the
Zone Temperature to the Zone Heating setpoint.

For units configured with Staged Heat once the control determines that there is an active heating
capacity request, the unit will energize the Supply Fan and ramp up to full speed. The control
methodology during Active Heating on units configured with Staged Heat types will be identical
to traditional Constant Volume units; heating stages will be energized/de-energized to meet the
Zone Heating demand.
Note: All Electric and Gas Heat staging sequences will be identical to Constant Volume unit
staging sequences.
Modulating Heat Operation with SZVAV Heating
Units configured with Modulating Gas Heat will utilize true Single Zone VAV control in the same
manner as during Active Cooling.
Heating Sequence
Once the unit control determines that there is a space heating demand, the unit will transition into
zone heating. Once the Discharge Air Temperature falls below the calculated discharge air
temperature setpoint, the unit will initiate the Modulating Heat output request and control the
supply fan at minimum speed. At this point, the Modulating Heat output will be controlled to
maintain the discharge air temperature requirements and the supply fan speed will be controlled
between 63%-100% to meet the zone heating requirements.
As the heating load in the zone decreases the fan speed will decrease down to minimum (63%) and
control the modulating heat output as necessary to meet the discharge air heating requirements.
As the load in the zone continues to drop the fan speed will be maintained at this minimum airflow
and the modulating heat output will be controlled accordingly.
Low Ambient Operation
The indoor fan motor (IDM) will operate at 100% fan speed during this evaporator defrost cycle
(EDC) and the compressor and outdoor fan will return to normal operation once the defrost cycle
has terminated and the compressor "Off" time delay has been satisfied.
Clogged Filter Option
The unit mounted clogged filter switch monitors the pressure differential across the return air
filters. It is mounted in the indoor section and is connected to the RTOM. The clogged filter switch
is normally open and will automatically close when the pressure differential across the filters falls
below the clogged filter setpoint. The RTOM will generate a SERVICE diagnostic that will be sent
to the zone sensor or remote panel when the clogged filter switch has been closed for at least 2
minutes during supply fan operation. The system will continue to operate regardless of the status
of the clogged filter switch.
Ventilation Override
Note: Applying 24 volts to one of the three Ventilation Override inputs manually activates
ventilation override. One input is provided to request the Pressurize Mode, the second input
the Purge Mode, and the third input the Exhaust Mode.
When the Pressurize Mode is selected, activating Ventilation Override will cause the supply fan to
run, the economizer to open to 100%, the exhaust fan to turn (remain) off, or the VFD to run at full
speed, and the VAV boxes to fully open.
When Purge is selected, activating Ventilation Override will cause the supply fan to run, the
economizer to open to 100%, the exhaust fan to run, or the VFD to run at full speed, and the VAV
boxes to fully open.
When Exhaust is selected, activating Ventilation Override will cause the supply fan to turn off, the
economizer to close to 0%, the exhaust fan to run (exhaust damper at 100% if configured for
Statitrac), or the VFD to stop, and the VAV boxes to operate normally.
RT-PRC056A-EN
25
Application Considerations
If more than one mode is requested at the same time, the Pressurize request will have priority
followed by Purge. When any Ventilation Override Mode is active, all heating and cooling is turned
off. For the case where the unit is required to turn off, the Emergency Stop input is used. The ICS
can also initiate any ventilation override mode. Table 3 lists the sequence of events within the
system for each ventilation mode. Refer to the unit wiring diagram for contact switching and wiring.
Note: Fresh air tracking will not work with VOM.

Affected Function
(a) Exhaust mode 3 is not available with the tracking power exhaust option.
(b) For units configured with the Statitrac option, the Exhaust Damper will open
during Ventilation Override modes that request the exhaust fan to operate.
Emergency Stop
When this binary input is opened, all outputs are immediately turned off and the system will not
be allowed to restart until the binary input is closed for approximately 5 seconds minimum. The
shutdown is communicated to Tracer™ if applicable and the Heat and Cool LED outputs (RTRM J67 and J6-8) will blink at a nominal rate of 1 blink per second.
Phase Monitor
The Phase Monitor is a 3 phase line monitor module that protects against phase loss, phase
reversal and phase unbalance. It is intended to protect compressors from reverse rotation. It has
an operating input voltage range of 190-600 VAC, and LED indicators for ON and FAULT. There are
no field adjustments and the module will automatically reset from a fault condition.
Low Pressure Control
This input incorporates the low pressure cutout of each refrigeration circuit and can be activated
by opening a field supplied contact.
If this circuit is open before a compressor(s) is started, the compressor(s) in that circuit will not be
allowed to operate.
Anytime this circuit is opened for 5 continuous seconds, the compressor(s) in that circuit are turned
off immediately. The compressor(s) will not be allowed to restart for a minimum of 3 minutes.
If four consecutive open conditions occur during the first three minutes of operation, the
compressor(s) in that circuit will be locked out, a diagnostic communicated to Tracer, and a manual
reset will be required to restart the compressor(s).
High Pressure Cutout and Temperature Discharge Limit
The high pressure controls and temperature discharge limit are wired in series between the
compressor outputs on the RTRM and the compressor contactors. If the high pressure safety or
temperature discharge limit opens, the compressor(s) on the affected circuit is locked out. If the
compressor output circuit is opened four consecutive times during compressor operation, the
RTRM will generate a manual reset lockout.
26
RT-PRC056A-EN
Application Considerations
Coil Frost Protection
The Frostat™ control monitors the evaporator coil temperature to prevent the evaporator from
freezing due to low operating temperatures whenever there is a demand for cooling. When a closed
circuit has occurred for 5 seconds minimum, the RTRM turns off all of the cooling outputs. The
Supply Fan will be held “On” until the Frostat has been opened for 5 continuous seconds or for 60
seconds after the last compressor was shut “Off”, whichever is the longest. The compressor
shutdown is communicated to Tracer, if applicable. There is no local diagnostic for this condition.
Failure and Override Modes
Certain failure and overriding conditions require special handling of the Supply Fan Speed on units
configured with Single Zone VAV. See below for a list of these conditions:
RT-PRC056A-EN
•
Supply Fan Proving Failure - If a Supply Fan Proving failure is detected, the Supply Fan will be
de-energized after 40s of run time and the Fan Speed output will go to 0 Vdc (0%).
•
Ventilation Override Mode - If a VOM goes active in which the Supply Fan is commanded ON
(Purge, Pressurize, etc.), the Supply Fan will be energized and the Fan Speed output will ramp
to 100%.
•
Zone Temperature Sensor Failure - If the Active Zone Temperature input goes out of range, the
unit will discontinue all Heating, Cooling, and Dehumidification operation.
•
Supply Air Temperature Sensor Failure - If the Supply Air Temperature input goes out of range,
the unit will revert back to Full Airflow, Traditional CV control. The unit will call out a Supply Air
Temperature Sensor Failure Alarm, the RTRM System LED will flash the 2-blink error code, and
the Zone Sensor Heat (Modulating Heat Only) and Cool LEDs will flash.
•
Frostat Failure - If a Frostat failure occurs, all active Heating, Cooling, and Dehumidification will
be de-energized immediately and the Supply Fan will ramp up to 100%.
•
Heat Failure (High Temp. Limit Trip) - If a unit configured with Gas Heat has a High Temp. Limit
trip, the Supply Fan will be requested to remain ON and the Fan Speed output will ramp to full
speed.

Selection Procedure
Cooling Capacity
Note: Cooling Capacity Procedure is the same for cooling (TZ) and gas/electric (YZ).
Step 1.
Calculate the building’s total and sensible cooling loads at design conditions. Use the following
calculation methods or any other standard accepted method. Factors used in unit selection:
Total Cooling Load: 180 MBh
Sensible Cooling Load: 126 MBh
Airflow: 6000 cfm
Electrical Characteristics: 460/60/3
Summer Design Conditions: Entering Evaporator Coil: 80 DB, 67 WB Outdoor Ambient: 95 DB
External Static Pressure: 0.39 in. wg
Rooftop—downflow configuration
Accessories:
• Roof curb
• Economizer
• Electric Heat
Step 2.
As a starting point, a rough determination must be made of the size of the unit. The final selection
will be made after examining the performance at the given conditions. Divide the total cooling load
by nominal Btu/h per ton (12 MBh per ton); then round up to the nearest unit size.
180 MBh / 12 MBh = 15.0 tons
Step 3.
Table 8, p. 38 shows that a TZD180F4 has a gross cooling capacity of 179.8 MBh and 145.5 MBh
sensible capacity at 6000 cfm and 95 DB outdoor ambient with 80 DB, 67 WB air entering the
evaporator.
To Find Capacity at Intermediate Conditions Not in the Table.
When the design conditions are between two numbers that are in the capacity table, interpolation
is required to approximate the capacity.
Note: Extrapolation outside of the table conditions is not recommended.
Step 4.
In order to select the correct unit which meets the building’s requirements, the fan motor heat must
be deducted from the gross cooling capacity. The amount of heat that the fan motor generates is
dependent on the effort by the motor—cfm and static pressure. To determine the total unit static
pressure you add the external static pressure to the additional static related by the added features:
External Static Duct System
0.39 in. wg
Standard Filter 2 in. from Table 20,
p. 49
0.05 in. wg
Economizer from Table 20, p. 49
(100% Return Air)
0.04 in. wg
Electric Heater Size 36 kW from
Table 20, p. 49
0.06 in. wg
Note: The Evaporator Fan Performance
Table 12, p. 44 has already accounted for
the pressure drop for standard filters and
wet coils (see note below Table 12,
p. 44). Therefore, the actual total static
pressure is 0.54 - 0.05 (from Table 20,
p. 49) = 0.49 in. wg.
(Reference “Heating Capacity,” p. 29 for
determination of heater size.) No additional static
add for gas/heat exchanger.
Total Static Pressure
28
0.54 in. wg
RT-PRC056A-EN
Selection Procedure
With 6000 cfm and 0.49 wg.
Table 12, p. 44 shows 1.70 bhp for this unit.
To calculate Fan Motor Heat, use the following formula:
3.15 x bhp = MBh.
3.15 x 1.70 = 5.36 MBh.
Now subtract the fan motor heat from the gross cooling capacity of the unit:
Net Total Cooling Capacity
= 179.8 MBh - 5.36 = 174.44 MBh.
Net Sensible Cooling Capacity
= 145.5 MBh - 5.36 = 140.14 MBh.
Step 5.
If the performance does not meet the required load of the building —total or sensible cooling load—
try a selection at the next higher size unit.
Heating Capacity
Note: Heating capacity procedures DIFFER for cooling (TZ) and gas/electric (YZ) units.
Step 1.
Calculate the building heating load.
Step 2.
Size the system heating capacity to match the calculated building heating load. The following are
building heating requirements:
TZ cooling units:
460 volt/3 phase Power Supply
Total heating load of 115.0 MBh
6000 cfm
The electric heat accessory capacities are listed in Table 22, p. 50. From the table, a 36 kW heater
will deliver 122.94 MBh at 480 volts. In order to determine capacity at 460 volts, the heater voltage
correction factor from Table 23, p. 50 must be used. Therefore, 122.94 MBh x 0.94 (voltage
correction factor) = 115.6 MBh.
YZ gas/electric:
Fuel natural gas total heating load of 195 MBh. Table Table 21, p. 49 shows 250 MBh and 350 MBh
input models. The output capacities of these furnaces are 203 MBh and 284 MBh respectively. The
low heat model with 203 MBh output best matches the building requirements.
Air Delivery Selection
Note: Air Delivery procedures is the same for cooling (TZ) and gas/electric (YZ) units.
External static pressure drop through the air distribution system has been calculated to be
0.50 inches of water. From Table 20, p. 49 static pressure drop through the economizer is 0.04 and
the 36 kW heater is 0.06 inches of water (0.39 + 0.04 + 0.06). Enter Table 12, p. 44 for a TZD180F4
at 6000 cfm and 0.49 static pressure. The standard motor at 558 rpm will give the desired airflow
at a rated bhp of 1.72.

2. For High Evaporator Fan Speed (rpm), reference Table 18, p. 48.
3. For Oversized Evaporator Fan Speed (rpm), reference Table 19, p. 48.
4. Fan motor heat (MBh) = 3.15 x Fan bhp.
5. Data includes pressure drop due to standard filters and wet coils. No accessories or options are included in pressure drop data.
6. For all non-standard sheave combinations, please refer to accessory installer’s guides ACC-SVN34*-EN and ACC-SVN72*-EN.
7. Factory supplied motors, in commercial equipment, are definite purpose motors, specifically designed and tested to operate reliably and continuously
at all cataloged conditions. Using the full horsepower range of our fan motors as shown in our tabular data will not result in nuisance tripping or
premature motor failure. Our product’s warranty will not be affected.
(a) Unit applications below 320 cfm/ton are only applicable to TZD models without electric heat and YZD models with modulating gas heat. See below for
restrictions.
- Electric heaters restricted on applications below 320 cfm/ton.
- Single zone VAV applications are capable of running below 320 cfm/ton during low speed airflow operation, but "full" airflow must be set to 320 cfm/
ton or higher.

Controls
Economizer Controls
The standard equipment offering is a fixed dry bulb changeover control. In addition, there are two
optional controls, Enthalpy and Differential Enthalpy Control.
Enthalpy Control
Replaces the dry bulb control with a wet bulb changeover controller which has a fully adjustable
setpoint. Enthalpy control offers a higher level of comfort control, along with energy savings
potential, than the standard dry bulb control. This is due to the additional wet bulb sensing
capability.
Differential Enthalpy Control
Differential Enthalpy replaces the standard dry bulb control with two enthalpy sensors that
compare total heat content of the indoor air and outdoor air to determine the most efficient air
source. This control option offers the highest level of comfort control, plus energy efficiency,
available.
Remote Potentiometer
Minimum position setting of economizer can be remotely adjusted with this accessory.
Zone Sensors
Zone Sensors are the building occupant’s comfort control devices. They replace the conventional
electro-mechanical thermostats.
Note: Zone sensor required for units configured for Single Zone VAV indoor fan and eFlex
compressor system control to enable Single Zone VAV and eFlex modulation functionality.
Differential Pressure Switches
This factory or field-installed option allows individual fan failure and dirty filter indication. The fan
failure switch will disable all unit functions and “flash” the Service LED on the zone sensor. The dirty
filter switch will light the Service LED on the zone sensor and will allow continued unit operation.

Mechanical Specifications
General
The units shall be dedicated downflow or horizontal airflow. The operating range shall be between
120°F and 0°F in cooling as standard from the factory for all units. Cooling performance shall be
rated in accordance with ARI testing procedures. All units shall be factory assembled, internally
wired, fully charged with R-410A, and 100 percent run tested to check cooling operation, fan and
blower rotation and control sequence, before leaving the factory. Wiring internal to the unit shall
be colored and numbered for simplified identification. This product has been evaluated to BiNational Standard CAN/CSA-C22.2 No. 236-05, UL 1995; and is eligible for CNL (Canadian National
Standards Listed) and USL (United States Standards Listed).
Casing
Unit casing shall be constructed of zinc coated, heavy gauge, galvanized steel. Exterior surfaces
shall be cleaned, phosphatized, and finished with a weather-resistant baked enamel finish. Unit's
surface shall be tested 672 hours in a salt spray test in compliance with ASTM B117. Cabinet
construction shall allow for all maintenance on one side of the unit. In order to ensure a water and
air tight seal, service panels shall have lifting handles and no more than three screws to remove.
All exposed vertical panels and top covers in the indoor air section shall be insulated with a 1/2-inch,
1-pound density foil-faced, fire-resistant, permanent, odorless, glass fiber material. The base of the
downflow unit shall be insulated with 1/2-inch, 1-pound density foil-faced, closed-cell material. The
downflow unit’s base pan shall have no penetrations within the perimeter of the curb other than
the raised 1 1/8-inch high supply/return openings to provide an added water integrity precaution,
if the condensate drain backs up. The base of the unit shall have provisions for forklift and crane
lifting.
Compressors
The Trane eFlex™ variable speed compressor shall be capable of speed modulation from 15Hz to
a maximum of 75Hz on the 12.5 ton units, and from 15Hz to a maximum of 70Hz on the 15 and 17.5
ton units. The minimum unit capacity shall be 25% of full load or less. The compressor motor shall
be a permanent magnet type. Each variable speed compressor shall be matched with a specially
designed, refrigerant-cooled, variable frequency drive which modulates the speed of the
compressor motor and provides several compressor protection functions. Control of the variable
speed compressor and inverter control, as well as tandem direct-drive, scroll type compressors,
shall be integrated with the ReliaTel unit controller to ensure optimal equipment reliability and
efficiency. Each compressor shall have a crankcase heater installed, properly sized to minimize the
amount of liquid refrigerant present in the oil sump during off cycles.
Controls
Unit shall be completely factory wired with necessary controls and contactor pressure lugs or
terminal block for power wiring. Unit shall provide an external location for mounting a fused
disconnect device. ReliaTel controls shall be provided for all 24-volt control functions. The resident
control algorithms shall make all heating, cooling, and/or ventilating decisions in response to
electronic signals from sensors measuring indoor and outdoor temperatures. The control
algorithm maintains accurate temperature control, minimizes drift from set point, and provides
better building comfort. A centralized control shall provide anti-short cycle timing and time delay
between compressors to provide a higher level of machine protection.
Crankcase Heaters
These band heaters provide improved compressor reliability by warming the oil to prevent
migration during off-cycles or low ambient conditions. These are standard on all Voyager models.
Defrost Controls
Adaptive demand defrost shall be provided to permit defrost wherever coil icing conditions begin
to significantly reduce unit capacity.
66
RT-PRC056A-EN
Mechanical Specifications
Discharge Line Thermostat
A bi-metal element discharge line thermostat is installed as a standard option on the discharge line
of each system. This standard option provides extra protection to the compressors against high
discharge temperatures in case of loss of charge, extremely high ambient and other conditions
which could drive the discharge temperature higher. Discharge line thermostat is wired in series
with high pressure control. When the discharge temperature rises above the protection limit, the
bi-metal disc in the thermostat switches to the off position, opening the 24 Vac circuit. When the
temperature on the discharge line cools down, the bi-metal disc closes the contactor circuit,
providing power to the compressor. When the thermostat opens the fourth time, the ReliaTel
control must be manually reset to resume operation on that compressor.
Evaporator and Condenser Coils
Microchannel coils will be burst tested by the manufacturer. Internally finned, 5/16” copper tubes
mechanically bonded to a configured aluminum plate fin shall be standard for evaporator coils.
Microchannel condenser coils shall be standard on all units. Coils shall be leak tested to ensure the
pressure integrity. The evaporator coil and condenser coil shall be leak tested to 225 psig and
pressure tested to 450 psig. Sloped condensate drain pans are standard.
Filters
Two inch standard filters shall be factory supplied on all units. Optional MERV 8 or MERV 13 filters
with filter removal tool shall be available.
Gas Heating Section
The heating section shall have a drum and tube heat exchanger design using corrosion resistant
steel components. A forced combustion blower shall supply premixed fuel to a single burner
ignited by a pilotless hot surface ignition system.
In order to provide reliable operation, a negative pressure gas valve shall be used on standard
furnaces and a pressure switch on furnaces with modulating heat that requires blower operation
to initiate gas flow. On an initial call for heat, the combustion blower shall purge the heat exchanger
45 seconds before ignition.
After three unsuccessful ignition attempts, the entire heating system shall be locked out until
manually reset at the thermostat. Units shall be suitable for use with natural gas or propane (field
installed kit) and shall also comply with California requirements for low NOx emissions. The 12½–
17½ tons shall have two stage heating (Gas/Electric only).
Indoor Fan
Units above shall have belt driven, FC centrifugal fans with adjustable motor sheaves. Units with
standard motors shall have an adjustable idler-arm assembly for quick-adjustment of fan belts and
motor sheaves. All motors shall be thermally protected. Oversized motors shall be available for
high static application. All indoor fan motors meet the U.S. Energy Policy Act of 1992 (EPACT).
Outdoor Fans
The outdoor fan shall be direct-drive, statically and dynamically balanced, draw-through in the
vertical discharge position. The fan motor(s) shall be permanently lubricated and shall have builtin thermal overload protection.
Phase Monitor
The Phase Monitor is a three-phase line monitor module that protects against phase loss, phase
reversal and phase unbalance. It is intended to protect compressors from reverse rotation. It has
an operating input voltage range of 190–600 Vac, and LED indicators for ON and FAULT. There are
no field adjustments and the module will automatically reset from a fault condition.
RT-PRC056A-EN
67
Mechanical Specifications
Refrigerant Circuits
Each refrigerant circuit shall have thermostatic expansion devices, service pressure ports, and
refrigerant line filter driers factory installed as standard. An area shall be provided for replacement
suction line driers.
Single Zone VAV
SZVAV systems combine Trane application, control and system integration knowledge to exactly
match fan speed with cooling and heating loads, regardless of the operating condition.
Note: Zone sensors are required for units configured for Single Zone VAV indoor fan and eFlex
compressor system control to enable Single Zone VAV and eFlex modulation functionality.
Variable Frequency Drive
Variable Frequency Drives are factory installed and tested to provide supply fan motor speed
modulation, as well as modulating gas heat. VFDs on the supply fan, as compared to inlet guide
vanes or discharge dampers, are quieter, more efficient, and are eligible for utility rebates. All VFDs
are designed to allow bypass if required. Bypass control will simply provide full nominal airflow
in the event of drive failure. Modulating gas heat models with VFD's allow tighter space
temperature control with less temperature swing.
Factory Installed Options
CO2 Sensor Wiring
The unit wiring for field installed C02 sensors. Factory-installed C02 sensor wiring saves time and
ensures proper unit connections for the field installed C02 sensor kits.
Complete Coat™ Microchannel Condenser Coil
The cathodic epoxy type electrodisposition coating is formulated for high edge build to a number
of different types of heat exchangers. The coating is selected to provide excellent resistance and
durability to corrosive effects of alkalies, acids, alcohols, petroleum, seawater, salty air, and other
corrosive environments. This coating shall be available on microchannel condenser coils.
Condensate Overflow Switch
This option shall shut the unit down in the event that a clogged condensate drain line prevents
proper condensate removal from the unit.

This offering meets the mandatory requirement of Title 24. This option provides detection of the
following faults: Air temperature sensor failure/fault, not economizing when it should,
economizing when it should not, damper not modulating, and excessive outdoor air. The FDD
system shall be certified by the Energy Commission as meeting the requirements.
High Short Circuit Current Rating
Unit shall be provided with electrical subsystem that will withstand fault currents up to 65kA (208/
230, 460 VAC) compliant with UL 1995 and NEC 440.4 (B). Each compressor circuit and the indoor
fan shall have dedicated overcurrent protection. Three phase motors shall be protected by Class
J time delay fuses. Single phase motors shall be protected by Class CC time delay fuses. All
transformers shall also be protected with Class CC time delay fuses. Contactors shall be din rail
mounted.
Hinged Access Doors
Sheet metal hinges are available on the Filter/Evaporator Access Door and the Compressor/Control
