The volt free wiring switches any voltage (not exceeding 230 V AC) supplied by the heat source when calling for heat.
-
Insert the pump supply voltage onto L1, N1, and connect the Earth.
-
Insert output supply to pump onto L2, N2, and connect the Earth.
-
Insert supply voltage onto B1 for boiler supply and output to boiler switch return on B2.
-
Connect L and N from a 3 A main supply.
230 V AC Wiring (to a zone valve)
The zone valve wiring centre allows you to switch each zone on and off individually, heating only the rooms you want at any given time.
-
Insert the heat probe onto T1 and T2 (not polarity specific).
-
Insert output supply to pump onto L2, N2, and connect the Earth.
-
Connect N1 with N3.
-
Connect L1, B1, and L3 with a Wago or connection block.
