switchmaster blue valve thingy

[stevads61]

Right....

Hubby got a replacement valve yesterday, spent most of the evening putting it in... pipework was no problem, got that done ok.

Electrics were another matter..... 6 wires (sorry, didnt realise till he removed the old one that there were 6 not 3) in the old one, 5 (I think) in the new one. He cant get the wiring right.

We've got the heating working but still no hot water

He's had several goes, will be having another go shortly... any tips/advice I can pass on??

Also for some odd reason our radiators seem hotter than usual and the boiler is quieter

Cheers

hi, i just changed 1, today. red is switched live/output to boiler and pump..orange hot water on(from cylinder stat)..yellow is heating on (from room stat).white can be permanent live but i wired it to the satisfied terminal of the cylinder stat and also run a wire from the water off terminal of the programmer to this same terminal. that way wether the cylinder stat goes off or water is off on the programmer there is a live feed for heating..
