N321 Electronic Thermostat

Description

The N321 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 that allows a compressor, or electronic heater, to bring the temperature back within the set point temperature limits (SP1, setpoint 1) set on the display. The N321 accepts 2 or 3 Wire PT100 temperature sensors.

Users can program the control action according to the application, direct action (refrigeration) or reverse action (heating). A single SPDT Relay (Max 250 @ 16A) allows for power a connected compressor, or electric heater, with ON/OFF control.
