F.A.Q.

 

When is a mixing valve open and when is it closed?

 

To answer this question, a distinction between versions with flow on the left and versions with flow on the right must be made. For versions with flow on the right: In case of a pointer position of 9:00 o’clock (scale=0), only return water is added to the flow. In case of a pointer position of 12:00 o’clock (scale=10), only water from the boiler flow is added to the flow. For versions with flow on the left: In case of a pointer position of 11:00 o’clock (scale=0), only return water is added to the flow. In case of a pointer position of 7:00 o’clock (scale=10), only water from the boiler flow is added to the flow. Please note that the direction of operation of the actuators has to be changed when converting the flow.
