GH26-P09 controller (with temperature sensors)

The GH26-P09 is among the most advanced controllers on the market. Designed to handle any type of solar thermal installation thanks to its extensive range of measurements and functions, together with the option of remote monitoring.

What does the GH26 controller offer?

The GH26 controller is an advanced and sophisticated solution designed to operate virtually any type of solar thermal system. It can be either a large solar thermal system or a small one designed not only to heat DHW, but also to support central heating or to heat swimming pool water. In addition, cooperation with an external heat source, such as a heating boiler, boiler or electric heater, is possible. Another important extension of the controller’s functionality is the possibility of connecting a pressure sensor in the solar thermal system.

Solar plant with EKONTROL extended remote monitoring

The wide range of functions that the GH26 controller has can be operated remotely using the EKONTROL system. Above all, convenient remote operation of the controller settings and viewing of the operating states of the solar thermal system are possible from the mobile app. Using a web browser, an animated diagram of the solar plant in operation and extensive statistics in the form of graphs and tables are additionally obtained.

For the highest demands – used in all climate zones

Due to its capabilities, the GH26 controller is particularly suitable for the high operating requirements of both the solar thermal system itself and its owner and operator. The controller is applicable in many countries with different climates and technical requirements – to this end, one of 22 languages can be selected for operation.
