INFORMATION
Shut-off valve usage example.
In case of two LWT zones, and a combination of
underfloor heating and heat pump convectors, install a shut-off valve before the
underfloor heating to prevent condensation on the floor during cooling operation. In
this case, the main zone cooling setpoint will not be adjustable. The cooling setpoint
for the heat pump convectors can be adjusted via the additional zone setpoint
screen.
