The N321 electronic thermostat are used to measure, indicate and control temperature in many different systems. Accepts 4 sensors types: Pt100, Pt1000, NTC or Thermocouple J. The user can program the control action according to the application: direct action (refrigeration) or reverse action (heating). The internal 10A relay can directly switch compressors or electrical heaters with ON/OFF control.
