Euroster 11M



Electronic, programmable controller designed for control of a three-way valve with actuator and CH circulation pump. It automatically maintains a constant temperature at a preset level or ensures a proper temperature of water in return piping in a CH system with coal-fired boiler. Possibility to connect a room thermostat. E11M controller is equipped with an AntiStop function which prevents seizure of the idle pump and valve rotor.


Controller function

  • keeps constant water temperature: in the central heating
    circuit or in boiler return
  • possibility of connecting room regulator
  • Anti-Stop function to protect pumps and valve against
  • frost protection
