SKU: N/A Category:

Central heating system regulation with mixer

Euroster 12M is a programmable weather controller for controlling the temperature of a heating circuit with a 3 or 4-way valve and controlling a central heating circulation pump. The system is equipped with a number of useful functions, e.g.: temporary switching on of a circuit with a set temperature (floor heating, fast heating of rooms), automatic turning the heating on and off depending on the outside temperature, protection against overheating of the circuit, or signalling of emergency situations. Euroster 12M has an anti-stall anti-stop pump system that prevents seizing 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).


  • Control of the 3-point actuator of the mixing valve
  • Heating circuit pump control
  • Weather-based determination of the heating circuit set temperature
  • Hourly heating circuit work schedule
  • Cooperation with a room regulator
  • Automatic switching off and on of heating depending on the outside temperature
  • The function of temporary switching on the circuit with the set temperature, floor heating, fast heating of rooms)
  • Protection against overheating of the circuit
  • Frost protection
  • Signalling emergency situations
  • Possibility of manual activation of outputs
  • Anti-Stop system – protection of pumps against stagnation
  • Readable, graphic, backlit LCD display
  • A set of temperature sensors included
