Thermo controller

The thermo controller is equipped with an overflow valve and a thermal control valve.
Overflow valve
In systems with a distribution manifold, the pump of the boiler charging set exerts an initial
pressure on the entire installation. If the overflow valve of the thermo controller is open,
the pressure can be reduced via the valve. Undesired circulation, which could lead to an
overcharging of the domestic hot water tank, can thus be prevented.
