ICM Controls ICM253 Post-Purge Fan Delay Timer is an adjustable off-delay control that keeps the blower or fan running briefly after a heating or cooling cycle ends to help purge residual air and improve system comfort.
This HVAC off-delay timer offers an adjustable 12 to 390 second off-time setting and a one-second interrogation delay to help prevent nuisance trips caused by thermostat bounce or tampering. It is a dependable choice for furnace, air handler, and general HVAC timing control applications.
