The boiler charging set can be mounted under/on a
distribution manifold. In this system the pump 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.
The following figure shows the adjustments necessary for
this system.
