Product description

Easy control of the heating / hot water pump

Euroster 11EK is an electronic, programmable controller, designed for cooperation with a central heating circulation pump or a pump filling the domestic hot water tank. It has an additional output to control a gas boiler or other heating device. The type of pump controlled is selected by software. Euroster 11EK is equipped with Anti Stop pump protection system, which prevents the seizing process of the unused pump impeller. After the end of the heating season, the system automatically starts the pump every two weeks for 30 seconds (for the system to work after the season, the controller should be left turned on).



  • A device for controlling the central heating circulation pump or pump charging the domestic hot water tank in heating installations
  • Software mode of selecting the type of controlled pump
  • Automatic activation and deactivation of the circulation pump according to the set central heating temperature
  • Supervision over maintaining a constant water temperature for the domestic hot water tank
  • Cooperation with circulation pamphas for solid or gas boilers (without pump control system)
  • Temperature measurement using a sensor that measures the water temperature at the heating flow or in the water heater
  • In the central heating installation with a solid fuel boiler, the regulator will switch off the circulation pump after the boiler flame has extinguished.
  • Frost protection and pump operation test
  • Setting the temperature above the dew point prevents the boiler from sweating during heating the water in central heating
  • The Anti Stop System, which prevents the seizing process of the unused pump impeller, which starts the circulation pump (also outside the heating season) for approx. 30 seconds every 14 days
