ICM255 Fan Blower Control Board

Description

The ICM255 Fan Blower Control Board 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. The bag is turned off at the end of the time delay period. If the initiate contact recloses during the time delay period, the burden 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.

The ICM255 Fan Blower Control Board comes packed with features. To start, it is low-cost and has an open board design. Also, it is high power and has a relay output. As well, it has a dual-function fan delay timer. Furthermore, it controls the circulating fan in the heat pump, A/C, and forced air systems. Lastly, its OFF delay purges ducts of residual air.
