Softus/Mike.
I have managed to sort this problem finally - it turns out that it WAS the programmer which was causing the problem (a DRAYTON LP112).
A pal of mine who is an electrician called today and changed this component and the fault seems to have disappeared.
Obviously something had...
Mick.
You're a gent.
It very much does appear, then, that the programmer is the culprit here.
Perhaps one of the "dry" joints on its circuit board has come astray and that's what is causing this prob.
Do you have experience of that sort of thing happening?
I have a pal who is going to...
Mick and Softus.
Many many thanks, guys. Appreciate it.
Just one question which is bothering me.
Is it possible that the Drayton LP112 programmer (if it is faulty) can interfere with the temperature of the HW?
As I say above, the cylinder stat is set at 60 degrees but the HW is heating...
Softus.
Hello. Thanks for your input.
I did explain the problem which had arisen (as detailed initially above) when the engineer initially called. The engineer immediately thought that the Diverter Valve was the "source" of the problem, rather than (as has turned out to be the case) an...
Thanks again, Mick.
Does it sound to you as if it's an electrical problem which can be fixed easily and quickly by a qualified heating engineer (given that it is a problem which has only presented itself very recently?).
And, as I asked previously, is the fault likely to be obvious within the...
Thanks, Guys.
The annoying thing about this is that I have just recieved a bill for £340 for the work done to replace the Diverter Valve and the Cylinder Stat, and the problem is still there.
Should the engineer have tested for an "electrical fault" BEFORE getting stuck into the changing of...
Thanks, Mick.
If it is a wiring fault will the fault be traceable/fixable within the junction box that brings the stat, programmer and valve wirings together?
Can anyone help?
I recently had a new 3-port Diverter Valve AND a new Cylinder Stat fitted to my central heating system because a problem had arisen whereby my CH was coming on okay when timed to do so but my HW was not.
Both are programmed to come on at 6am (I have a Drayton LP112...
