To connect the shut-off valve

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.
1 Connect the valve control cable to the appropriate terminals as
shown in the illustration below.
NOTICE
Wiring is different for a NC (normally closed) valve and a
NO (normally open) valve.
