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.
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. A dip
switch is provided to enable automatic
fan operation in heat mode. Useful for
straight electric heat or hydronic heat
applications. Fan operation is
seamless and occurs without
interruption from Cool to Heat mode.

The panel has seven built-in Delay Timers
that insure safe & reliable operation.
*Built-In
Timer
Settings
* Start-up Delay Timer = 3 minutes-fixed
* Short Cycle Timer = 3 minutes-fixed
* Change Over Timer = 4 minutes-fixed
* Opposing Call Timer = 20minutes-fixed
* 2nd Stage Timer = OFF, 7-42 min. -Adj.
* Supply Air Limit Timer = 3minutes-fixed
* Purge Delay Timer = 90 seconds-fixed
*Startup

Timer
The panel will not activate a cooling
or heating operation until the startup
delay has expired. This occurs after
any initial power up, after any power
failure or after pressing the Reset
button for 7 seconds.
*Short Cycle
Timer
When the system is satisfied, the
panel will not resume the same mode
for a minimum of 3 minutes.
*Changeover
Timer
*Opposing
Call
Delay Timer
A 20 minute delay must expire, or the
active zone(s) must satisfy, before
the panel will honor a thermostat
demand to changeover to the
opposite mode of system operation.
*2nd Stage
Timer / OAS
The 2nd STAGE TIMER sets the
amount of continuous call time in 1st
stage, before second stage heat or
cool is energized. NOTE: The
potentiometer also serves as the
2nd stage Heat Outside Air
Changeover Setting.

A built-in timer prevents the system
from rapidly switching between
heating and cooling modes. At the
end of a call, a 4 minute timer is
started and the panel will not switch to
the opposing mode until the timer has
expired.
The BMPlus 3000 can inhibit 2nd
stage heat based on a Timer or
Outside Air Temperature.
NOTE: An Optional OAS Sensor is
required to use the OAS feature.
NOTE: 2nd stage cool delay defaults
to 15 minutes, if OAS is chosen to
inhibit 2nd stage Heat.
The time delay of 3 minutes must
expire before the BMPlus 3000 will
re-energize heat or cool mode. This
occurs when the processor detects
the supply air temperature is higher
or lower than the High or Low
temperature limit settings.
The last Damper(s) will be held Open
for 90 seconds at the end of every call
allowing a system purge into the last
zone that was calling.

The Adjustable Cooling Limit
potentiometer sets the supply air
temperature at which the cooling is
cycled off and the fan continues to run,
allowing the coil to warm up.
The Adjustable Heating Limit
potentiometer sets the 1st stage heat
supply air temperature, at which the
heating is cycled off and the fan
continues to run, allowing the heat
exchanger or coil to cool down.
The Adjustable 2nd stage heat
differential potentiometer sets the 2nd
stage heat supply air temperature, at
which the heating is cycled off and the
fan continues to run, allowing the heat
exchanger or coil to cool down.
NOTE: Allows the supply air sensor to
be installed in the supply air plenum,
regardless of the coil/heat exchanger
configuration. Allows the installer to fine
tune virtually any 2 stage heating
system!
The separate reset buttons on the
old BMP3000 have been replaced
by a single button with dual
functions. Momentarily pressing the
RESET button clears the built-in timers
controlling the Startup delay timer,
Short cycle timer, W2 timer, Supply air
sensor timer and the Changeover
timer. This enables you to test the

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. NOTE: If HP is selected at dip switch 1, Y2 is not available. Y2 is only available in GAS mode.
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.
HC < TSTATS > HP
Select HC, if you want to use regular Heat/Cool thermostats on your job. Select HP, if you want to use Heat Pump
thermostats on your job. Remember that you can use standard HC T-stats on a Heat Pump application.
IMPORTANT NOTE: The BMPlus 3000 Zone Control System allows Heat Pump thermostats to be connected to all zones.
When doing so, make sure you turn the 2nd stage timer to the “OFF” position. Using heat pump thermostats means that the
zone panel will obey thermostatic demands and ignore Timer operations. This comfort over-ride feature provides a level of
versatility to your zoning system and gives the homeowner comfort control over the system, instead of waiting for the
adjustable timer to energize 2nd stage heat.
O < RV > B
Select the correct Reversing Valve signal for your particular Heat Pump. Choose “O” for any heat pump that energizes
the RV in the cooling mode. Choose “B” for any heat pump that energizes the RV in heating mode.
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. If DF or OAS has been selected, the 50% rule will apply to
cooling operations only. 2nd stage heat will not be affected. The 50% rule will always dominate the 2nd stage timer or
thermostat demands unless Emergency mode is active.
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. There is no need to move this switch when setting up for Heat Pump operations.

The BMPlus will accept heat pump style
thermostats in all zones. This allows you to
energize 2nd stage heat thermostatically instead of
through the W2 timer. Also, Emergency heat can be
activated from any zone.
NOTE: The New BMPlus 3000 allows the user to install Heat
Pump thermostats on all zones. This allows the user to turn
off the W2 Timer and energize the auxiliary heat via
thermostatic demand! You may still use regular Heat/Cool
type thermostats with a Heat Pump system and use the W2
Timer to energize the auxiliary heat. Doing so may save more
energy. This new design simplifies the thermostat selection
process and allows the installer to easily adapt the BMPlus
3000 to any residential applications.

Figure 10 Single stage heat pump and 1or 2 stage furnace.
**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 CONV or DF at dip switch #2. Install regular
Heat/Cool thermostats and choose to activate 2nd stage heat by TIMER or
by OUTSIDE AIR TEMPERATURE. (Optional Sensor required). Or you may
choose to install Heat Pump Thermostats on all zones and turn the Onboard Timer OFF. When the thermostat 2nd stage heat demand is satisfied,
the BMPlus 3000 will stage down, unless DF or 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 all current heating
demands are 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.

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
such as Spring Types, Isolation relays and separate power supplies may 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.

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/BMPlus circuit 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 & the BMPlusB
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
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.
Make sure that you wire and configure your thermostats for the correct application. Most thermostats built today can be field
configured to operate as regular Heat/ Cool type or as Heat Pump type. Remember that you can use regular Heat/Cool
thermostats on the BMPlus 3000 for Heat Pump applications.
