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
