Thank you all for your helpfull replies. Last night, in order to check the wiring safely I turned off the supply to the control box. Having checked the wiring I turned the supply back on. The hot water required heating, and this time the radiators did not get warm. Since I found no problems with...

Thanks for that Maltaron. I'll certainly use that when I check the wiring in the morning. Just for info, what voltage should I expect to read across the white and neutral when the tank thermostat is making contact?

Thank you for your reply. I've had to go out for a while. I'll take a further look when I get back. However, as I mentioned earlier in this thread. No work has been done on the wiring so I am not sure how it could now be wrong.

Hi Jackthom, Thanks again for your reply. I was measuring across white grey. With the system at rest I measure across white and neutral a small leakage of 13.2 mV and across grey and neutral 240V. With the thermostat on the tank activated I measured 240V across white and...

Hi Jackthom, Thanks very much for the reply. With the system at rest I measured 240v across the white and grey wires. When I moved the tank thermostat until it engaged the reading across the white and grey wires dropped to +/- 20v (but was not steady). Then the in-out thing...

Thanks for the very speedy reply. Since this problem has only just reared it's head, and before it manifested no changes had been made to the system, I don't suspect a wiring fault. However, I will go check. Why oh why are these things always so damn inaccessible.

Hi, Having read several of the posts here concerning radiators warming up when the hot water was heated, I concluded that my three port valve needed replacing. I'm reasonably technical and did the job myself, however, it doesn't seem to have solved the problem. My radiators are still...
