Our Solar systems are managed and operated by solar controllers.

As soon as the temperature of the collector exceeds the store temperature, the controller activates the circulation pump and the heat medium liquid transports the heat, taken up at the collector, into the hot water store (constant differential temperature regulation).
Conventional heating systems ensure a required after-heating within the store. 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. Heating Solutions differential temperature controllers are used in solar, heating and air-conditioning 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. Precision temperature sensors are used for measuring purposes. Those sensors are available in various mechanical versions and are interchangeable.

In basic terms, for hot water generation only, if the temperature differential between the bottom of the cylinder and the solar panel exceeds 8 degrees, the controller activates the solar pump. Alternatively if the sensor located at the top of the cylinder is lower than 40 degrees the alternative heat source is activated. This may be an oil boiler, pellot boiler etc.

This ensures that the solar cylinder is always to temperature and only calls in the boiler when the solar panel cant heat the cylinder
