Euroster 813 ot a modern solar installation controller that controls the temperature of solar collectors and a maximum of two hot water tanks, depending on the selected operating mode. The device is able to control an additional heat source (boiler or electric heater) providing additional heating during periods when the energy obtained from the solar collector is insufficient. The user can program the time periods during which the additional heating is switched on. The controller can work in one of 4 modes, the list of available modes depends on the connection of sensors that are automatically detected when the power is turned on, which prevents the setting of an incorrect operating mode. The installation diagram for each mode is displayed on an ongoing basis on a clear display of the controller.
