Product description

Precise solar control

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.



  • The controller is intended for the solar system
  • The ability to work in one of four modes (depending on the connection of sensors):
    • work with 1 container (2 sensors)
    • operation with 1 container and an additional electric heater (3 sensors)
    • operation with 1 storage tank and an external heating system (3 sensors)
    • operation with 2 storage tanks and a switching valve (3 sensors)
  • Automatic detection of connected sensors
  • Protection against setting the wrong operating mode
  • LCD display on which min. installation diagram for each of the operating modes
  • Supervision over the temperature of the solar collector and up to two tanks
  • Possibility to control an additional heat source (boiler or electric heater) providing additional heating at times when the energy obtained from the solar collector is insufficient
