And thanks to Dilalio too..... sorry

Thank you Echo the Husky and Gas2Air for your time, expertise and for the effort with dealing with a non-plumber/heating engineer. And thank you for saving me a bundle of cash because if I'd followed the advice from what has been posted on other sites I would have unnecessarily replaced the...

Right then. Joined Terms 1 & 3 together. It all just kicks into life. Rads are starting to warm up. From this I take it that it was my stat that was knackered and that I'll have to control it manually or by timer until I can get a new one. Are they repairable or will it need replacing?

Right off to test this out. Will be a little while.

Just getting my head around what you said. I understand. Pretty certain there's a label inside the SCR showing which wire is which

Put it on the actual pump casing itself. I can test again putting probe on valve neutral/blue wire. Cylinder/Hot Water is hot Green light is on SCR - when I reduce temp on stat it flashes red then goes off when increase temp flashes red and then goes green as it should Pressing Override button...

Right, heating has gone again. I've done some tests. It doesn't look like a loose connection. Multimeter says: Grey = 240+V Orange = 0 White = 0 These tests were done with the water off at the programmer - but get same results with it on. One of the probes was connected to the relevant...

Keeping this post bookmarked - it has some useful info on it.

I'm going to check all the wiring and make sure all the connections are tight but at the moment it's working and I don't want to risk losing heat again. When I do it I will attach it to the wall as well. Thank you for all your advice.

I never even got to open the connection box as when I moved it from under the floorboards in the airing cupboard the heating burst in to life. I'm guessing (hoping) that there is a loose connection in there somewhere but I'm not going to touch it just yet as the house is warming up and we're...

I will, but will have to do it tomorrow too much wine to mess with electrics right now = can barely type (took about 6 attempts to write this) Yesterday I couldn't spell plummer, now I are nearly are one.

Right, I'll get a meter on them as soon as I can. These measurement do I take them from the valve head or from the connection box, or does it not matter. If it's from the valve it's gonna be a pig. Still Learning Yesterday I couldn't spell plummer, now are one.

I don't know if this makes any difference to what I have said about the valves workings 3 Position Diverter Valve Replacement head part is 4000 3916 003 If it is kaput, I've been looking at replacements. Is this a mid-position valve? Do I go for the whole valve or just replacement head or...
