Description:

Solar thermal controller is a mandatory element of solar systems with forced circulation of the coolant. It is designed to control the process of heating from the sun and monitor the state of the solar system. The controller receives information from temperature sensors (one of which is installed at the output of the solar collector) and regulates the operation of the circulation pump. The efficiency and safety of the solar system largely depend on the controller: the correctness of the laid down algorithms for the solar system, the reliability of the elements.
The SR 868 Series controllers are standard controllers with a range of commonly used functions. They are used for small solar systems with an additional heater.
