Wiring (continued)
Apply power to DR65A3000. Turn the humidity control to a low RH% level to initiate a dehumidification call.
Confirm that the DR65A3000 compressor and fan turn on. The furnace blower will also turn on to circulate
air. This will take up to two minutes. Be sure to turn the control to the desired RH% or to Off when checkout
is complete. Turning the humidity control to Off will turn the DR65A3000 off.
