ICM255 Dual Function Fan Delay Timer control board

ICM Controls ICM255 fan blower control board. Board measures 2.5" x 2.5".

Power must be applied before and during the time delay period. When the initiate contact closes, the load energizes and remains energized as long as the initiate contact is closed. The time delay begins when the initiate contact opens. At the end of the time delay period, the load is turned off.

If the initiate contact recloses during the time delay period, the load remains energized and the time delay is reset to zero. Removal of the input power during the delay turns off the load and resets the time delay to zero. A one-second interrogation delay is provided to avoid nuisance trips due to thermostat bounce or tampering.

Input voltage 18-30 VAC
NO: 20 amps resistive @ 240VAC
