    If no request for heating or domestic hot water is received for 24 hours, the circulator starts automatically for 10 seconds to avoid any blockage.
  • Blockage protection in 3-way valve
    If no heating demand is received for 24 hours, the 3-way valve automatically performs a complete operating cycle.

    This device limits the pressure in the heating circuit to 3 bars.
    Do not use to drain the heating circuit.
