Customer:

Hi . are you wiring in a room stat?

JACUSTOMER-i9ztb263- : 2x 2 port valves with a switching live from the wiring centre
Customer:

In the boiler wiring centre there will be a 240v switched lived connection. There will also be low voltage or volt free inputs. Don't use those

JACUSTOMER-i9ztb263- : Ok so where does the switched live go?
Customer:

Have you got the boiler model or GC and I will check the wiring diagram,

JACUSTOMER-i9ztb263- : VAILLANT 630 system boiler
Customer:

Ok , give me a minute, thanks

JACUSTOMER-i9ztb263- : ok
Customer:

Page 27, 230v section .remove the link in 3 and 4 and put switched lie in 4. If 4 didn't work it will be 3.

JACUSTOMER-i9ztb263- : Is that the Bus terminal?
Customer:

No the bus is for specialised ebus controllers, usually weather compensation units etc

JACUSTOMER-i9ztb263- : Ok so not the low volt rf either?
Customer:

No . the motorised valves etc work off 240/ 230volts , so the power from the switched live will be the same . if you put it in the low voltage or bus you may damage the boiler pcb

JACUSTOMER-i9ztb263- : Ok so any links that need removing or linking over?
Customer:

If there is a link in 3 and 4 in the 230volt section you can remove it and put switched live in 4

Customer:
