Designed for manual or automatic control of solar systems for water heaters with one hot water circuit. In automatic mode, the pump is switched on when the temperature difference between the collector and the storage tank has reached the adjustable value ?T. If ?T is below the set value or if the maximum tank temperature Tmax. (adjustable) is reached, the pump is switched off and there is no further charging. The digital display shows one of three selectable temperatures. The solar controller consists of a control unit and a maximum of 3 temperature probes (2 probes are supplied with the system).
The control unit and probes are connected by two-core signal cables (max. length 50 m).
Two probes detect the temperatures necessary to control the collector (TK) and the storage tank (TS). display the temperature of an additional measuring point (TM) (e.g. buffer tank).
Similar to SR 1, but with integrated overheating protection function. In automatic mode, the overheating protection prevents excessive temperatures in the solar circuit if no water is withdrawn or in case of intensive sunshine. The pump remains on even if the set maximum storage tank temperature Tmax. is exceeded. This allows the system to be cooled down via the collector after sundown. When Tmax. is reached, the pump is switched off. If the maximum collector temperature is exceeded in automatic mode, the pump is switched on to prevent further heating up, thereby protecting the collector from possible damage.
