right. Fixed! :D problem was indeed a faulty tank thermostat despite only being replaced about 6 months ago. Popped down to screwfix and got another L641a and wired it in, instant boiler fire up for CH and HW, im still confused as to how this prevented CH fire up tho? Mikely, thank you so...

Thank you.Ive just tested that and the thermostat (L641a) works correctly, but, when the stat reaches the desired temp, shouldnt terminal 7 then become live? HW off? i have this connected to the grey wire on the 3 port valve but this wire is not live at any point

ah, that link works without the comma on the end, yes thats the one im using what i meant by" L-5-8 does not supply a feed to my airing cupboard at all" is, if i put my circuit tester on the orange wire from the 3 port valve in the connector block in my airing cupboard, there was no voltage...

That link you posted doesnt work but thanks, i'll see if i can google it i used a honeywell .pdf but this one is identical http://octaveblue.co.uk/c_heating/hw1_ch1.htm

hiya, orange live feed, white and grey wires, blue neutral and an earth. 5 wires

Need a little help please. I fitted a new honeywell 4073 3 port valve on saturday and was unable to get the boiler to fire afterwards for HW and CH. ive checked my wiring a million times and finally sussed there is no boiler and pump live feed to the airing cupboard. im at a loss as to why? i...

So. my sunvic SDM 1901 3 port failed and after seeking advice on here i have replaced it yesterday with a honeywell v4073. unfortunately, the room stat does not fire up the boiler at all,ever, and the boiler seems controlled entirely by the tank stat, which leaves the boiler nearly...
