Apply power to TrueDRY DH65. Turn the humidity control to a low RH% level to initiate a humidity call. Confirm that
the TrueDRY DH65 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 this back down (or off) when checkout is complete. Turning the humidity control
to Off will turn TrueDRY DH65 off.
