Thermal
Circuit
Breaker
The BMPlus module has a Thermal
circuit breaker that protects the
module(s) from shorts in the damper
and thermostat field wiring. It will
not protect against shorts in the
HVAC system wiring.
CAUTION: When the circuit breaker
is tripped it will get quite hot. To
reset the breaker: Shut off power to
the panel. Find and repair the short.
Restore the 24VAC power.
Watch Dog
Circuit
The processor has a built-in feature
that monitors the processor
performance and resets the system if
an error occurs in operations or due to
power failures.
Indoor Fan
Control
Any zone can activate the indoor fan
and only the dampers in zones calling
for continuous fan operation will open.
Continuous fan operation will only
occur when there are no active or
pending, heat or cool demands.

Choose the type of HVAC system you want to control. Select HP, if your system is any type of heat pump. Select GAS,
if your system is a standard Gas or Oil furnace. Also applies to straight electric furnaces or hydronic (hot water coil)
heating systems.
DF < HP > CONV
Choose the type of Heat Pump you want to control. Select DF, if your system is a dual fuel heat pump with gas or oil
furnace backup heat. Select CONV, if your system is a conventional heat pump with electric resistance backup heat.
Also applies to Ground source/Geothermal heat pumps.
ON < FAN DELAY > OFF
Select ON, if you want the indoor blower forced ON at the end of a heat/cool call to assist the zone purge cycle.
Selecting OFF will allow the HVAC system to operate the indoor blower, without interference from the BMPlus.
90S < PURGE > 120S
Select 90S or 120S, if you want the zone dampers to hold position for 90 seconds or 120 seconds at the end of any
heat/cool call. This allows the HVAC system to purge the remaining hot/cold air, into the zone(s) that were calling for it.
OAS < 2nd STAGE > TIMER
Select OAS, if you want to delay 2nd stage heat based on the outside air temperature sensor. Select TIMER, if you
want to delay 2nd stage heat & cool based on the adjustable on-board timer. NOTE: 2nd stage cool defaults to a 15
minute delay, when OAS is chosen. NOTE: An optional Outside Air Sensor (OAS) is required to use the OAS feature.
OFF < 50%RULE > ON
Select OFF, if you do not want to inhibit 2nd stage heat/cool based on the total number of zones calling. Select ON, if you
want to inhibit 2nd stage heat/cool based on the total number of zones calling. More than half the total zones must be
calling for the same mode, or 2nd stage will not activate. NOTE: If HP has been selected at dip switch 1, Y2 is not
available. If DF or OAS has been selected, the 50% rule will apply to cooling operations only. 2nd stage heat will
not be affected by this setting. The 50% rule will always dominate the 2nd stage timer unless Emergency mode is active.
IMPORTANT NOTE: The BMPlus 3000 Zone Control System allows a 2 stage heating thermostat to be wired to Zone 1 only!
Energizing this terminal results in over-ride of any stage 2 heating delay. The BMPlus will remain in 2nd stage mode until that
terminal is de-energized. If this occurs in dual fuel mode or emergency mode, the BMPlus will stay in 2nd stage until the
heating demand is satisfied. On the next demand for heat, the BMPlus will attempt to activate 1st stage heat unless,
Emergency Mode is still active, or the outdoor temperature is low and OAS / DF has been selected. This comfort over-ride
feature provides true versatility to your zoning system, and gives the homeowner a level of comfort control over the system.
OFF < SAS > ON
Select OFF, if you do not want to use the supply air sensor included with the BMPlus Zone Control system. Select ON, if
you intend to use the included supply air sensor. Refer to the data sheet included with the supply air sensor for details.
GAS < FAN > HYDRONIC
Select GAS, if your HVAC system is a gas or oil forced air furnace. Select HYDRONIC, if your HVAC system has a hot
water coil, or straight electric heat with no indoor blower support. Useful when you need the indoor blower to run
automatically in heat mode, just like it does in cool mode. NOTE: When you select HP on dip switch #1, the indoor fan
mode is automatically set for you.

INSTALLATION INSTRUCTIONS and THERMOSTAT WIRING
Installation should be performed by qualified
personnel only. Follow local & national electrical &
mechanical codes. Use multi-conductor 18 awg solid
copper conductors. Wire number to number or letter to
letter on each control.
EMERGENCY MODE
Use the optional/Illuminated Remote Emergency
Switch to activate Emergency heat, or use the OnBoard Emergency Heat Switch, or use a multi-function
Heat Pump Thermostat.
WARNING: THESE PANELS ARE DESIGNED FOR USE
WITH 24VAC. DO NOT USE OTHER VOLTAGES! USE
CAUTION TO AVOID ELECTRIC SHOCK OR
EQUIPMENT DAMAGE.
Mount the panel housing in a suitable/convenient location.
Mounting hardware is provided. Use the knockouts
provided on the panel housing as entryways into the
housing. Strain relief fittings can be used if desired. Use
care and do not damage the circuit board when making
wire connections.
NOTE: The 24 vac power required to operate a BMPlus

**Note that a Conventional & Dual fuel heat pump wire up more or less the
same. The difference is how 2nd stage heat operates. In a Conventional
system, the indoor fan & the compressor continues to run when 2nd stage
energizes. In a Dual Fuel system, the indoor fan & the compressor shuts
down when 2nd stage energizes. The BMPlus 3000 will perform these
functions automatically. All you have to do is set the dip switches to the
correct settings. Select DF or CONV at dip switch #2. Choose to activate
2nd stage heat by TIMER or by OUTSIDE AIR TEMPERATURE. (Optional
Sensor required) You can also use a 2 stage heat thermostat at Zone 1 that
will over-ride the delays if the thermostat demands it. When the thermostat
2nd stage heat demand is satisfied, the BMPlus 3000 will stage down,
unless DF/OAS has been selected and the outdoor temperature is lower
than the OAS changeover setting. In that case the system will continue in
FUEL mode, until the heating demand is fully satisfied.

HVAC system with OEM Voltage Control Circuitry
Some HVAC manufacturers are designing HVAC Systems
with 5 - 18 vdc control circuits. Standard 24 vac thermostats
will not work on these systems. These systems can only be
controlled with their own thermostat. But the SYSTEM
connections on a BMPlus 3000 are all dry contacts! Virtually
any HVAC low voltage control circuit can be connected and
controlled. All you have to do is ask the manufacturer which
numbered terminal corresponds to the standard terminals.

Note that you can route a Common lead back to the “System” terminal
block, but it should never be connected!
Use it as a TEST point while troubleshooting. It should be marked as
such and, remain capped off when not in use!

ENHANCED FEATURES AND FUNCTIONS
MODULE TO MODULE FACTORY POWER WIRING
SHORTED ZONE FEATURE FIRMWARE
The BMPlus 3000 includes Factory Power
Wiring on all expanded systems. The 24 vac
power to the expansion modules is fed
through the bus cable. This simplifies your
wiring and minimizes the chances of reversing
polarity.
The BMPlus 3000 Zone Control System
includes the Shorted Zone Feature. This
feature allows the BMPlus to ignore demands
from a zone thermostat that is putting out
simultaneous demands for heat & cool. A
condition most likely due to a short in the field
wiring, incorrect wiring, or a defective
thermostat. The BMPlus will honor any
legitimate demands from any other zone(s),
except the shorted zone. When the problem is
identified and repaired, the BMPlus 3000 will
automatically recognize that zone.
DUAL FUEL COMPATIBLE
The BMPlus 3000 is compatible with Dual Fuel
Heat Pumps. Dual Fuel kits are not required.
Select staging based on Adjustable Time
Delay or an Optional Outside Air temperature
Sensor. The intelligent firmware does the rest.

DAMPER WIRING AND CONFIGURATION
Note: All zone dampers default to the "OPEN"
position after a purge delay has occurred.
Dampers also default “OPEN” during
changeover & short cycle delays, and when
all zone demands are satisfied, and no
signals are detected from the thermostats.

DAMPER WIRING CONTINUED
If you need to connect numerous dampers to a single zone, or you are using dampers of unknown current draw,
Isolation relays and separate power supplies will be required. Parallel as many dampers as you want as long the
total current load of the motor actuators does not exceed the VA rating of the transformer. Other factors should
also be considered, such as the full load amp rating of the isolating relay contacts, voltage drops from long wire
runs and feeder conductor sizing to junction points.
NOTE: Some older style dampers and competitor’s dampers cannot be paralleled and must be isolated or wired
in tandem. Contact EWC Controls Technical Support for assistance.

SYMPTOM
SOLUTIONS
LED’S are responding properly but
HVAC system is malfunctioning.
Check HVAC system wiring for proper connections.
Check HVAC system wiring for shorts/miswiring.
Check HVAC System.
Refer to Technical Bulletin for correct Setup/Wiring/Dip Switch settings.
LED’s are not responding properly
and HVAC system is malfunctioning.
Check HVAC system wiring for shorts/miswiring.
Check HVAC system wiring for proper connections.
Check HVAC thermostat for proper connections.
Refer to Technical Bulletin for correct Setup/Wiring/Dip Switch settings.
LED’s illuminate and HVAC system
functions normally but dampers do
not respond.
Check damper motor wiring for proper connections.
Check damper motor 24vac transformer voltage/fuse/BMPluscircuit breaker.
Check damper motor wiring for shorts/miswiring.
Refer to Technical Bulletin for correct Setup/Wiring.
REFER TO THE DAMPER MOTOR TESTING PAGE 8
LED’s do not illuminate and HVAC
system does not respond.
Check HVAC/BMPlus system transformer supply voltage.
Check HVAC/BMPlus system 24vac transformer voltage/fuse/BMPlus circuit
breaker.
Check HVAC/BMPlus system wiring for shorts/miswiring.
CHECK YOUR WIRING
DETECTING 24vac SHORTS
SYMPTOMS: Module(s) appear to be dead!
HVAC system not responding and
BMPLUS 3000 LED’s are off.
Dampers not responding and THE
BMPLUS 3000 LED’s are off.
If 24vac short has occurred, 24vac will be present at the BMPlus 3000 Module
Input terminals R & C; but 24vac will not be present at the Thermostat R&C.
ISOLATING 24vac SHORTS
Disconnect the wire(s) from the ‘R’ terminals on the BMPlus 3000 thermostat
terminal blocks , and the “M2/M4/M6’’ terminals on the BMPlus 3000 damper
motor terminal blocks. Restore power. If the short is no longer present, Ohm
out the thermostat and damper field wiring for shorts/misconnections. Replace
or repair wires as necessary. Restore power. Module(s) will resume operation.
F1 circuit breaker protects the
BMPlus 3000 and reacts to a short in
the damper motor or thermostat
component and field wiring.
SOLUTIONS: Remove 24vac power from BMPlus 3000 and allow circuit breaker to cool!
Find and repair short(s) in damper and/or thermostat field wiring. Restore 24 vac power.
TESTING THERMOSTATS
During a demand for heating, the thermostat should apply a 24vac hot signal to the W and or W2 terminals.
During a demand for cooling, the thermostat should apply a 24vac hot signal to the Y and G terminals.
During a continuous fan demand, the thermostat should apply a 24vac hot signal to the G terminal.
Check to make sure that the thermostat Rc and Rh terminals are connected together, unless your application requires
separation of these circuits.
Use the (C) Common terminal provided at each thermostat terminal block to wire up full 24 vac hard-wired thermostats.
You should reference the (C) Common terminal when troubleshooting incoming thermostat demand signals, even if no wire is
connected there.
