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
HEAT PUMP THERMOSTATS
HEAT/COOL THERMOSTATS
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 BMPlus 3000 allows the user to install Heat Pump
thermostats on all zones. You may still use regular
Heat/Cool type thermostats with a Heat Pump system and
use the Staging Timer to energize the auxiliary heat. If you
don’t have enough wires available. It is advisable to use
Heat/Cool thermostats with 2 stage compressor Heat Pumps.
A single 24vac, 40va
UL Listed transformer
can power the
BMPlus3000 Main
module with up to 12
genuine ND or URD
dampers. See page 9
for more load and
transformer data.
