Description
The Novus N322S is a high-efficiency differential temperature controller specifically engineered for solar water heating and thermal energy management. Designed to optimize heat transfer, the N322S monitors the temperature gradient between two independent NTC sensors, typically mounted at the solar collector and the storage tank, to intelligently activate the circulation pump only when a usable energy gain is detected. This dual-output unit provides a high-capacity 16A main relay for direct pump control and a secondary 3A auxiliary relay that can be configured for backup heating or safety alarms. With built-in protection logic to prevent pipe freezing in winter and system overheating in summer, the N322S is a robust, all-in-one solution for solar thermal installations, swimming pool heating, and industrial heat recovery systems.
