ICM-UDEFROST

With the high cost and limited access to OEM replacement boards, the need for a singular Universal defrost control board which replaces the function of nearly all time & temperature heat pump defrost controls is a must. ICM controls has what you need with the ICM-UDefrost board. The added benefit of selecting the ICM-UDefrost is the ease of configuration using the ICMOMNI mobile App downloaded free to your Apple or Android Mobile device.

The ICM-UDefrost board monitors thermostat calls for Y, O/B and W2 inputs. During a heat call if conditions for defrost are met, the control will perform a time and temperature defrost cycle. During normal operation, the control continuously monitors safeties such as the low-pressure switch, high-pressure switch, brownout detection, and sensor health while displaying status and fault conditions via onboard LED diagnostics.
