Apply power to TrueDRY DH150. Turn the humidity control to a low RH% level to initiate a humidity call. Confirm
that the TrueDRY DH150 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 DH150 off.
