Novus N321S - 80321S3314

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 provides protection against overheating and freezing to the piping, preventing damages to the system.
