The N321R Electronic Thermostats are designed for refrigeration application with a programmable defrost cycle that can turn off a compressor at pre-determined time intervals for a specific duration. Manual Defrost key is also available on the front panel. The N321R accepts NTC Thermistor temperature sensors. A single SPDT Relay (Max 250 @ 16A) allows for power a connected compressor with ON/OFF control.
The N321R Electronic Thermostats include a single control relays and are designed to measure, indicate and control temperature in many different systems by controlling a single relay for ON/OFF control. A programmable defrost cycle can turn off a compressor at pre-determined time intervals for a specific duration. Manual Defrost key is also available on the front panel. Temperature readings are taken using a NTC Thermistor temperature sensors.
