adjustable minimum damper position,
damper assembly slides in unit, outdoor
air hood must be ordered separately,
optional down-flow barometric relief
dampers available, choice of economizer
controls. The IMC add−on board for
economizer control is included with the
economizer. Control board has five
choices for controlling the economizer
(DIP switch selections).
1 − Differential Sensible Control −
Factory setting. Uses the outdoor air
and return air sensors that are
furnished with the unit. The IMC
compares the outdoor air and return air
and using setpoints, enables the
economizer when the outdoor air
temperature is below the configured
setpoint and cooler than return air.

can be configured to Single Sensible
Control. The IMC compares the
outdoor air sensor temperature to the
setpoint and enables the economizer
when the outdoor air is cooler than the
setpoint.
3 − Global Control − The IMC
communicates with a DDC system with
one global sensor (enthalpy or sensible)
to determine whether outside air is
suitable for free cooling on all units
connected to the control system. Sensor
must be field provided.
4 − Single Enthalpy Control − Outdoor

HUMIDITROL® HOT GAS BYPASS REHEAT OPTION
156H & 180H (3 Compressors)
210H, 240H & 300S (4 Compressors)
R−22 CAV MODELS ONLY
Factory installed option designed to
control humidity.
Provides dehumidification on demand
using ASHRAE 90.1 recommended
method for reheat with comfort
conditioning humidity control.
In addition to a thermostat/room sensor
used for conventional operation, a
humidity sensor is required and must be
located in the occupied space.
Humidity sensor provides input to the
Integrated Modular Control (IMC) which
is used to control activation of the
dehumidification operation.
Reheat controls are located in the
compressor control section of the unit
for easy access.
Benefits
Improves indoor air quality.
Helps prevents damage due to high
humidity levels.
Improves comfort levels by reducing
space humidity levels.
Operation
No Dehumidification Demand
The unit will operate conventionally
whenever there is a demand for cooling
or heating and no dehumidification
demand.
Free cooling is only permitted when
there is no demand for dehumidification.
Dehumidification Demand Only
The IMC is factory set at 60% relative
humidity setpoint and can be adjusted at
the IMC or with optional Unit Controller
Software.
For Network Control Panel (NCP)
applications, the humidity setpoint can
be adjusted at the NCP. The unit will
operate in the dehumidification mode
until the relative humidity of the
conditioned space is 3% below the
setpoint.
Reheat operation will initiate on a
dehumidification demand and does not
require a cooling demand.
The reheat coil is sized to offset most of
the first stage sensible cooling effect
during reheat only operation. This
reduction in sensible cooling capacity
extends compressor run time to control
humidity when cooling loads are light.
Solenoid valves divert hot gas from
compressor 1 and compressor 2 to the
reheat coil.
The cooled and dehumidified air from
the evaporator is then reheated as it
passes through the reheat coil.
The de−superheated and partially
condensed refrigerant continues to the
outdoor
condenser
coil
where
condensing is completed.
The unit will continue to operate in this
mode until the dehumidification demand
is satisfied.
A heating demand will terminate reheat
operation.
Dehumidification and Cooling Demand
for 156H/180H three compressor
models (Thermostat Application)
If both a dehumidification and a first
stage cooling demand occur, the system
will operate compressor 1 and
compressor 2 in reheat and compressor

A demand for second stage cooling will
terminate reheat operation until second
stage cooling demand is satisfied.
Dehumidification and Cooling Demand
for 210H/240H/300S four compressor
models (Thermostat Application)
If both a dehumidification and a first
stage cooling demand occur, the system

IMC M1−7
AFTERMARKET ZONING SYSTEM INTERFACE
Introduction
Lennox’ seventh generation premium rooftop unit (RTU) controller, the Integrated Modular Controller (IMC) version M1−7,
along with a variable frequency drive (VFD) option on certain L Series® and S−Classt RTUs, increases the ability of premium
Lennox RTUs to be applied to a variety of zoning systems. The type of zoning system to be used dictates the type of RTU and
the requirements for the zoning control system. The following explains each basic system and how the IMC must interface
with an aftermarket zoning control system to meet the requirements of each application.
Lennox units in single zone and constant volume bypass applications may utilize an aftermarket unit controller as
supervisory controller for the RTU. The IMC runs in thermostat mode and is primarily useful for diagnostic purposes, allowing
the aftermarket controller to directly monitor and control heat/cool staging, the bypass damper, zone dampers, economizer
damper, etc. When the IMC is used in thermostat mode, a maximum of two stage heating and three stage cooling are
available. An optional Four Stage Control (FS1) board may be added to allow four stages of heating and cooling control.
Supervisory control must be provided by the Lennox IMC to minimize complication and standardize control on Lennox
VFD−controlled variable air volume (VAV) RTUs. In this configuration, the IMC controls the VFD based on static pressure in
the supply duct. It controls the economizer, and stages compressors based on discharge air temperature. The aftermarket
controller simply sends calls for cooling or heating based on setpoint and schedule conditions. The IMC also has many
options for controlling single−stage, 50% power exhaust fans; two−stage, 100% Power exhaust fans; or modulating power
exhaust fans.
NOTE − Please refer to the IMC Manual (M1−7 Version 5.0x) for additional details.
Interface Definition
With a aftermarket control system interface, the IMC requires four digital inputs to control the rooftop unit: G (blower enable),
OCP (occupied), Y1 (enables discharge cooling), and W1 (enables discharge heating).
This application minimizes the controls expertise required to create a viable interface. Further, it creates a consistent,
standardized approach conducive to support and trouble−shooting on a broad basis without the need for substantial
knowledge of the IMC, VFD, bypass, or aftermarket controllers or systems.

AFTERMARKET ZONING SYSTEM INTERFACE
Sequence of Operation
IMC Supervisory Control
Operation when IMC blower (G) input is energized
When a G signal is present, the IMC controls the VFD or bypass damper to hold a constant supply duct static
pressure based on the input from the IMC pressure sensor using a PID control loop. For increased flexibility,
the IMC has separate adjustable static pressure setpoints for ventilation, cooling, heating and smoke
alarms. These set points reside in the memory of the IMC, have factory default settings, and may be
adjusted in the field prior to start up.
Operation when IMC occupied (OCP) input is energized
When an OCP signal is present the IMC adjusts the fresh air damper to either a fixed minimum position or
allows it to modulate based on a CO2 sensor. The CO2 sensor can be wired directly to the IMC, to another
controller that can monitor the sensor and pass a signal to the IMC for damper control, or to both the IMC and
another device for monitoring through the desired man−machine interface while the IMC maintains damper
control. During morning warm−up/cool−down the IMC keeps the fresh air damper closed based on the IMC
configuration settings selected. The set points for minimum and maximum damper position setting and CO2
control reside in the memory of the IMC, have factory default settings, and may be adjusted at start up. They
cannot be adjusted using the aftermarket controls system.
Operation when IMC first stage cooling (Y1) input is energized
When a Y1 signal is present the IMC controls up to 4 stages of cooling (depending on RTU size) to maintain a
cooling discharge air temperature setpoint. These stages include mechanical cooling, or outdoor air for
cooling with an economizer. The discharge air temperature setpoint resides in the IMC, has a factory default
setting, and may be adjusted at start up. It cannot be adjusted using the aftermarket controls system. The
IMC has advanced discharge−air cooling reset options selected at start up based on return air temperature
and/or outside air temperature. Outside air reset saves energy by gradually increasing the discharge air set
point as outside air temperature decreases. Return air reset reduces potential for overcooling if the zoning
system is misapplied or has an abnormal condition or dominant zone. The reset gradually increases
discharge air temperature as return air temperature decreases.
Operation when IMC first stage heating (W1) input is energized
When a W1 signal is present, the IMC controls up to 4 stages of heating (depending on RTU size) to maintain
a heating discharge air temperature. The heating discharge air temperature set point resides in the IMC, has
a factory default setting, and may be adjusted at start up. It cannot be adjusted using the aftermarket controls
system. The IMC has advanced discharge air heating reset options based on return air temperature and/or
outside air temperature. Outside air reset saves energy by gradually decreasing the discharge air set point
as outside air temperature increases. Return air reset reduces possibility of overheating if the zoning system
is misapplied, has an abnormal condition or dominant zone. The reset gradually decreases discharge air
temperature as return air temperature decreases.
Power Exhaust Fan Operation
The IMC has many power exhaust fan control options that include single−stage, two−stage and modulating
control depending on how the unit is equipped. Stage control options can be triggered based on fresh air
damper positions, pressure switches, or a pressure analog sensor. Modulating control for units with VFD
powered exhaust fans are typically modulated to maintain return or building static pressure, but can be
staged. Set points and operation settings for controlling power exhaust fans reside in the IMC, have factory
default settings, and may be adjusted at start up. They cannot be adjusted using the aftermarket controls
system.
