Hi again fellas...little help please, just been to a job where a chappie has brought a house with an old ch system in and it has an old manual hw/heating divertor valve on it and wants it replaced with a new up to date rf roomstat/programmer,cylinder stat as well as control for his hot water.
It looks like a 2 port m/v will do the trick (looks like old valve just sits on flow to cylinder) and i was just looking for a decent wiring package to fit. I'm no expert in this catagory as i mainly deal with fitting combi's so any help would be welcomed.

Sundial RF² Pack 3 (Y9420S1005)

Follow the instructions in the box and you're away.

You do need 2 x 2 port valve on the system 1 on heating 1 on Hot water side and remeber to fit a bypass as it now an interlocked system so the water has to circulate somewhere to cool otherwise it'll vent.

Good luck

No need. Deep double back box, 30amp terminal strip and a blank cover plate that'll do you.

oh..ok, but because i dont do this very often and the sundial wiring centre tells you where all the wires go and they are only £6 on fleabay i think it maybe wise for me to get one. i thank you for your help.
