Product description

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 signaling 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).
