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 a pressure on the
entire installation. When the overflow valve in the thermo controller is open, the pressure can be
reduced via the valve. Undesired circulation, which could lead to overcharging of the domestic
water tank, can thus be prevented.
