Eliwell Ewcm 900 S

Check system charge; inspect filters and electronic expansion valves. Compressor Protection Interlock Safety switch tripped (thermal overload or oil level)

By reading the outdoor ambient temperature via an auxiliary probe, the EWCM 900 S can dynamically adjust the condensing pressure setpoint. Lowering the head pressure during cooler ambient conditions significantly reduces the electrical power consumption of the compressors. Installation and Wiring Best Practices eliwell ewcm 900 s
