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
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.
A 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.
