Installation & Operation Instructions 800.558.1711
A control can be used with the B70DHV. Broan oers the DEH 3000 proprietary control. The DEH 3000
monitors and controls relative humidity and proper ventilation levels in their home. This control is also available
with a remote sensing option. The B70DHV features a built-in dehumidistat control as well as the ability to wire
a remote mounted control to the unit. If the B70DHV is located outside of the area where humidity control is
desired, consider using a remote wired humidity controller that is located in the area where humidity control is
desired. If using the built-in dehumidistat to control the unit, locate the control in an area where it can accurately
sense the humidity of the area where humidity control is desired. If the B70DHV is located in the area where
humidity control is desired, consider using the built-in control. Adjust the humidity control so that the unit
maintains the desired level of humidity.
Note: The DEH 3000 is sold seperately and can be purchased online or through your local dealer. Other
thermostats are compatible with the B70DHV.
CONTROLS
CAUTION!CAUTION!
DO NOT ALLOW THE 24V TERMINAL FROM THE B70DHV TO CONTACT THE COM
TERMINAL ON THE B70DHV OR DAMAGE TO THE TRANSFORMERS WILL RESULT.
Circuit Breaker
To prevent damage to the 24 volt control transformer, the B70DHV comes with
a resettable circuit breaker. Check wiring for any electrical short and repair before
resetting breaker. Resetting the circuit breaker without correcting the electrical short may
result in transformer damage. Be sure to check the electrical schematic in this manual
or inside the access panel of the B70DHV before making any control connections.
The reset button for the circuit breaker can be found on the back of the unit.
Control Connections
The control and the B70DHV are labeled to prevent confusion. Depending on the
control, some of the screw terminals on the B70DHV may not be used. Be sure
to consult the electrical schematic in this manual or inside the access panel of the
B70DHV before making control connections.

Compressor OFF / Fan ON Make contact between 24V and FAN terminals
Power HVAC Accessory Connect the accessory to the DMPR and 24V terminals
Between the COM lead and the 24V TERMINAL is a 40VA transformer. This low voltage power source
powers the relay coils which control the fan and compressors. This 24VAC transformer can also be
used to power HVAC accessories external to the dehumidier.
