Description

The N321S and N322S controllers are intended for solar water heating applications. They control the water circulation system based on the difference of temperature between the solar collector and the storage tank (or swimming pool). The instruments contain two NTC-type temperature sensors and a control output for activating the water circulation pump. It provides protections against overheating and freezing to the piping, preventing damages to the system.
