Reznor 259780 Relay Els PW 17895 and 48HCD series unitsThe Reznor 259780 Time Delay Relay is a critical OEM component engineered for sequence control in Reznor HVAC systems. Specifically utilized in RP PGBL model duct furnaces and packaged units, this 120V time delay relay (Thermodisc #12S22 305587) regulates the activation of blower motors and fans to prevent rapid cycling. By coordinating the start up sequence between the burner and the distribution fan, it protects electrical contacts from premature
