As soon as the temperature of the collector exceeds the storage tank temperature, the controller activates the circulation pump and the heat medium liquid transports the heat, taken up at the collector, into the hot water storage tank.

Conventional heating systems ensure a required after-heating within the storage. Because of the easy integration into building techniques and an average life expectation of more than 25 years, solar systems are an ideal complement to modern heating technology

Cib differential temperature controllers are used in solar, heating and heat pump systems to initiate switching processes depending on thermal, hydraulic and environmental conditions.

In general, the controller monitors the determined temperature differences of the sensors and compares them to the given set temperature differences. The controller is switched on if the adjusted temperature difference is exceeded. The system is controlled by one or more relays. Pumps or electric valves may be connected to these relays.

The controller also support remote monitor.
