The N322S is a controller intended for solar water heating applications. It controls the water circulation system based on the difference of temperature between the solar collector and the storage tank (or swimming pool). 

The instrument contains two NTC-type temperature sensors and two outputs: 

  • A control output for activating the water circulation pump
  • A booster output

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

CE (European Union) and UL (United States and Canada) certifications compliant.
