Installation & Wiring Instructions - EWC Controls BMPlus 3000 Technical Bulletin

INSTALLATION & WIRING INSTRUCTIONS
WARNING: THESE PANELS ARE DESIGNED FOR USE WITH 24VAC. DO NOT USE OTHER VOLTAGES! USE CAUTION TO AVOID ELECTRIC
SHOCK OR EQUIPMENT DAMAGE. ALL WORK SHOULD BE PERFORMED TO LOCAL AND NATIONAL CODES AND ORDINANCES. USE 18
AWG SOLID COPPER, COLOR-CODED, MULTI-CONDUCTOR THERMOSTAT CABLE.
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.

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
