EWC Controls BMPlus 3000 Service manual

The BMPlus Zone Control System allows you to easily
upgrade an inefficient single zone HVAC system, into a
Multi-zone, Energy savings, Comfort producing, HVAC
system. The Superior Design, Intuitive Firmware, Simple
Setup Options, Easy to Understand wiring and Backwards
Compatibility, makes the BMPlus Zoning system the
Contractors dream. Combined with EWC Motorized
Dampers and Any off-the-shelf Thermostats, EWC Controls
sets a another high standard in the residential & light
commercial Forced Air Zoning Industry.
The main module controls three zones
using motorized dampers and may be
expanded up to 5, or 7 zones, using 1 or
2 XM2 Expansion Modules.
Controls 2 stage conventional or dual fuel
heat pumps, without the need for dual fuel
kits. Also single or two-stage gas, oil, &
hydronic heating systems, with single or
two stage air conditioning. Constant or
variable speed fan systems.
Compatible with any off the shelf
Heat Pump Thermostat
(2heat/1cool). You may also use
any regular Heat/Cool thermostat
(1heat/1cool). You may still use
regular Heat/Cool thermostats to
control a Heat Pump system.
The BMPlus Zone system features
automatic changeover from any
thermostat allowing for individual zone
comfort from the HVAC system.
The STATUS LED pulses as a steady
heart beat to indicate active Micro-
processor status.
On board LED’s illuminate to indicate
HVAC system mode, system status,
active and inactive zone identification.
See page 10 for details.
LEDs labeled Zone 1 thru Zone 7 indicate
which dampers are energized open.
All modules operate on 24vac power
supplied from a separate transformer. A
single 40va transformer can power up to 7
zones with a total of 7 ND/URD dampers
directly connected. See page 9 for
details.
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.
When the system is satisfied, the
panel will not resume the same mode
for a minimum of 3 minutes.
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 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.
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 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 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.

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

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.
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.
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.
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.
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.
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.
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.
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.
Programming and setting up the BMPlus
3000 to control your HVAC system is very easy!
Look below for an explanation of each dip
switch function and choose your settings.
Some functions may not apply to your application.
Then use a pencil to mark/record your settings. If the

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.

HEAT PUMP THERMOSTATS
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.

HEAT/COOL THERMOSTATS
Common wire may not be required on your thermostat.
*
Mount the panel housing in a suitable/convenient location. Mounting hardware is provided. Avoid locations that may become wet or
produce condensation. Hot attics are OK. Use the knockouts on the panel housing as wire entryways. Strain relief fittings can be used
if desired. Use care and do not damage the circuit board when removing the knockouts and making wire connections. NOTE: The
24vac power supply should be supplied by a separate transformer. DO NOT use the 24vac power supply from the HVAC system
unless there is no other alternative. 2 zones and 2 dampers is the limit when stealing voltage from the HVAC system.
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.

**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 On-
board 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.

* Note: Your Air Handler may include a W terminal. That means
it may have it’s own isolation circuit. If you can confirm this,
simply connect the W1/B terminal to the W terminal on the air
handler. Do not cut the Rc/ Rh jumper. Wire up your Oil Burner,
Circulator relay, or Hydronic Zone valve to the isolation
contacts or wires provided in the air handler. The fan is
controlled via the time delay relay inside the air handler.
Don’t worry if you accidentally cut the Rc/Rh link. Just install your
own jumper across the Rc/Rh terminals!

BMPlus 3000
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.
Theoretical diagram only shown below.

Warning: All of the wiring diagrams provided are
general in nature and may not perfectly match your
particular application, due to differences in HVAC Mfr’s
design and terminal designations and functions!
Variations on these diagrams and other System or
Thermostat applications are available by contacting the
EWC Technical Support Hotline.
ENHANCED FEATURES AND FUNCTIONS
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.

* SIMPLIFIED WIRING AND EASY SYSTEM SETUP
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.
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.

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

NOTE: Do not connect more
than 4 motor actuators in a
series configuration. That will
decrease the chances of poor
electrical connections and
voltage drop issues.

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.
Non-inherently current limiting transformers must have field provided over-current protection on the secondary 24 vac output. The table values
provided pertain to genuine ULTRAZONE Dampers and Competitors typical 24vac Spring loaded dampers. Included in these VA load ratings are the
correct number of thermostats, the BMPlus Zone System, and a 5% field factor. Spring loaded dampers draw higher currents & require more power.

TROUBLESHOOTING
REFER TO THE DAMPER MOTOR TESTING PAGE 8
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.
F1 circuit breaker protects the
BMPlus 3000 and reacts to a short in
the damper motor or thermostat
component and field wiring.
CHECK YOUR WIRING
EWC Controls provides superior toll free Troubleshooting Support for the BMPlus 3000 when you are on the job site!
Call 1-800-446-3110 Monday - Friday 8am to 5pm EST
Otherwise call 1-732-446-3110 for information on the BMPlus 3000 and other ULTRA-ZONE products..
When calling for Technical Support, please have a multi-meter, pocket screwdriver, and wire cutter/stripper handy.
TECHNICAL SUPPORT
LED’s do not illuminate and HVAC
system does not respond.
LED’s are not responding properly
and HVAC system is malfunctioning.
LED’S are responding properly but
HVAC system is malfunctioning.
SYMPTOM
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.
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.
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.
SYMPTOMS: Module(s) appear to be dead!
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.
