Functions:

The controller is automatically filling the water tank. When using hot water, the water level in the tank goes down. The sensor located in the tank will open the solenoid valve, which will allow water to come in from the water supply network. When the tank is full, the controller closes the valve. In addition, there is the possibility of controlling the water temperature. In the absence of sunlight, it is possible to automatically heat the water with the use of electric heating cables or an electric heater.

Mainly for solar systems from the YL and QG series (non-pressure). It is used for automatic topping up of water in the tank directly from the water supply network.
