or differential pressure sensing in ductwork

Replacing an old 100111990 modulating valve restores the system's ability to adjust heat output dynamically

Built for continuous duty

its wide coil voltage range allows it to be powered directly from most standard control power sources

Copeland 940-0150-69 Compressor Relay 340155-7024 or differential pressure sensing inThe Copeland 940 0150 69 Compressor Relay is a high duty 24 VAC startup component engineered for heavy load commercial refrigeration and air conditioning systems. Designed as a direct OEM replacement relay, this unit supports currents up to 40A, acting as the critical interface between the control signal and the compressor motor. By precisely regulating the start and stop functions, it prevents high amperage surges and reduces electrical stress on the
