ActronAir Compressor Discharge Sensor 084Z6036 "Hercules" (Danfoss) is the Danfoss-supplied compressor discharge temperature sensor for Hercules commercial systems, providing continuous discharge temperature monitoring to the CM100 board for compressor protection and capacity management. This is a Danfoss-specific component with a proprietary connector and thermistor characteristic -- substituting a generic NTC sensor with a different resistance curve causes incorrect temperature readings that may mask overtemperature conditions in the Hercules compressor circuit. Isolate power and recover refrigerant before replacing any Hercules refrigeration circuit components.
