Product description

Two controllers in one!

Euroster 11Z is a programmable controller for simultaneous cooperation with a central heating circulating pump and a pump filling the domestic hot water tank - an economical solution in the case of the necessity of using two pumps in independent central heating and domestic hot water systems. gas. In the DHW system, the controller maintains a constant water temperature in the tank or in the domestic hot water system, with or without priority for tank loading. Euroster 11Z 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).



  • The device for independent control of the central heating circulation pump and the pump charging the domestic hot water tank in heating installations
  • 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
  • Temperature measurement using a sensor that measures the water temperature at the heating flow and in the water heater
  • In a 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
  • Protection against water cooling in the hot water tank
  • DHW priority function
  • Setting the temperature above the dew point prevents the boiler from getting wet during heating the water in the heating system
  • 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
  • Possibility of installing a domestic hot water temperature sensor in a domestic hot water tank or in a hot water system (third tube)
