Copeland Comfort Control (White Rodgers) 90-113 Relay/Trans Precision Compatibility: Specifically engineered forThe Copeland Comfort Control (White Rodgers) 90 113 Fan Relay Transformer is a heavy duty HVAC control center designed to manage line voltage fans and pump motors in both forced air and hydronic systems. This component integrates a 120V to 24V Class II transformer with an SPDT relay, allowing high voltage equipment to be safely switched by a 24V thermostat signal. Built for field service efficiency, it mounts directly to a 4 x 4 inch junction box and
