Could the "internal wiring" within the Programmer body itself rather than the "external" connections which hook it up to the other components on the system be causing the issue - and once again, if so HOW?

Hello again DH. Sorry for the delay in replying but I thought I would wait until the engineer had been to do his stuff and see if this problem would now be sorted. I wanted to keep a close eye on the behaviour of my system over a period of time to make sure all was right (sad I know)...

I've got this same engineer calling back again on Thursday morning to this time carry out a full wiring and component check to see if the problem can be traced to its source, and I can have my central heating system back again in proper working order. Would I be right in saying that the...

And this new Cylinder Stat was installed simply by removing the wires connected to the old one and connecting them to the new one - no access was gained into the wiring centre to make sure that the "other end" of the cable was in proper order.

I think there are 3 active wires to the cylinder stat.

Thank you both, gentlemen. The 3-port and cylinder stat were both replaced as stated by a supervising heating engineer from the firm with whom I have a Central Heating insurance cover policy. I have a feeling that it was simply easier for him to replace these components rather than carry out...

Could it be the Programmer? And if so, in what way? I ask this because , as stated above, the 3-port and the cylinder stat are both brand new and have been recently positively tested.

Anyone out there who is good with wiring faults on a central heating system? Can you make an educated guess on this please? Is it possible that my Drayton Lifestyle Programmer could be possibly "interfering" with the proper and effective working of my cylinder stat if the wiring is...

Well - blow me down! The problem has made a come-back, after exactly 2 weeks. Exactly the same issues as before. The only question that begs an answer ( given that it simply HAS TO BE a wiring glitch) is why the hell the engineer who called did everything he could to avoid having to look at...

Hello Matt. Engineer replaced the Cylinder stat. He said that he had dealt with the exact same problem last week and had done the same - and has heard nothing untoward about it since. He said that a thorough examination of the system's wiring would be quite a lengthy procedure - and said...

Appreciate the input, sir. Would you therefore be broadly in agreement with Matt1e that the most certain way to get to the bottom of this is a thorough testing of all circuits and components with a multi-meter and that this will most likely reveal the source of the problem? John.

Yes - that's correct. But the valve which is currently in place was fitted only 7-8 weeks ago. Surely it has to be more robust than that - otherwise there would be an epidemic of these valves going faulty in that way. Most people have their 3-port valves working in exactly this sort of...

One last question - Can you explain why this is an intermittent fault rather than a constant one? I can't quite get my head round why it happens on only an occasional basis. What exactly causes this sort of fault to make its presence felt only now and again? Is it possible to explain in layman's...

Methinks you're right - I have to get set for work right now. I will let you know how it is resolved after the professional has been to look at it. This whole thing might be of help to someone else in the future if they get a similar problem. In the meantime - Thank you so much for your...

Matt. I did try turning HW on and CH on and turning both stats up - the valve went (as it should do) to mid-position. Boiler fires up to heat both "channels" (as it should do). I will try and get my daughter to help me upload a pic of the wiring in the terminal centre as you've requested...
