N321S Differential Temperature Controller, 240 VAC Powered

The N321S is a controller for solar heating applications. It typically commands a water circulation pump through the temperature differential between the solar collector and the thermal reservoir or pools.

The controller has two inputs for NTC-type temperature sensors (supplied with the controller) and one control outlet for activating the water circulation pump.

It also includes function for preventing damage to during deep winter and high summer, thereby preventing plumbing damages (burst pipes) and thermal discomfort. CE (European Union) and UL (United States and Canada) certifications compliant.
