the integrated relay is specifically designed to interlock with an exhaust fan

Industrial Durability: Constructed with materials resistant to the thermal stresses common in commercial mechanical rooms

or a specific flash code on the control board indicating a pressure switch stuck open or pressure switch stuck closed error

The medium temperature charge (Code C) is optimized for suction temperatures between -20°F and +50°F

meaning both coil terminals (#10-32 studs) must be wired to complete the circuit

Copeland 071-0649-02 Module Protector 322838-752 the integrated relay is specificallyThe Copeland 071 0649 02 Module Protector is a critical external protection component designed for heavy duty HVAC and refrigeration compressor applications. Operating on 24 VDC, this module serves as a primary defense against electrical overloads and catastrophic winding failure. For technicians managing commercial refrigeration systems, this unit provides a precise 30 minute reset delay, effectively mitigating risks associated with short cycling and
