INFORMATION
Shut-off valve usage example. In case of one LWT zone, 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.
For more information, see the installer reference guide.
