Description
Market Products Co. 28470000 Fan Delay Relay functions as a vital HVAC systems component. The fan delay relay operates the blower fan of units through its control mechanism. When the thermostat demands heat or cool the relay creates a brief pause before starting the fan operation. The system delay enables the heating element or cooling coil to achieve its temperature before airflow begins which stops sudden temperature changes when the cycle starts. The fan maintains operation after the cooling cycle finishes to pull out the remaining warm or cool air from the system which enhance operational efficiency.
