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 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  to 5 or 7 zones, using 1 or 2  
Model 

XM2 Expansion Modules

.

Controls 2 & 3 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 
H e a t   P u m p   T h e r m o s t a t  
(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.

green

 STATUS LED pulses as a steady 

heart beat to indicate Micro- processor 
activity and 24v power is present. 

Function specific colored LED’s illuminate 
to indicate the HVAC system mode of 
operation and active zone identification. 
See page 10 for details.

Green LEDs labeled Zone 1 thru Zone 7 
indicate which dampers are energized to 
the open position.

INPUT VOLTAGE:

 19-30VAC 60 Hz

Transformer 40-100VA MAX. NEC Class 2.

CURRENT DRAW:

 Max 15VA @ 24VAC.

OVER-CURRENT PROTECTION:

 4.0 amp 

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.
