Installation under a distribution manifold
•
The zone module can be mounted under 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 type of
installation:
Domestic

Overflow valve open
