Novus N321S - 80321S3014

The N321S is a controller intended for solar water heating applications. It controls the water circulation system based on the difference in temperature between the solar collector and the storage tank (or swimming pool).

The instrument contains two NTC-type temperature sensors and a control output for activating the water circulation pump. It protects against overheating and freezing to the piping, preventing damages to the system.

These temperature controllers are used to measure, indicator and control temperature in a wide range of applications! The front is IP65 and the output is a relay, SPDT.

Our Novus N321 temperature controllers are available in four different sensor inputs; Pt100, Pt1000, thermocouple J or thermister.
