Reznor 97479 Relay Els PW 17895 occupancy sensorsThe Reznor 97479 Time Delay Relay is a critical field service component designed for precise sequence control in Reznor gas fired unit heaters. Engineered for high duty cycle applications, this DPDT (Double Pole Double Throw) relay manages the timing of the blower motor and inducer fan, ensuring the heat exchanger reaches optimal temperature before airflow begins and purging residual heat during the post purge cycle. Operating on a standard 24V
