Hi Rob,
My response may not have been very clear.
I found a Honeywell frost stat which is installed above the boiler (just above the roof line) of the garage.
However, there is no pipe stat installed on the return pipe.
Therefore, I believe that my issue is that the garage is getting...
Hi,
Just managed to find a Honeywell FrostStat installed in the garage - never spotted it.
Is it possible that the frost stat kicks in at around 10 degrees and there is no pipe stat so it stays on for a long time?
Where would the pipe stat normally be installed if I have one and should...
Thanks
I might just change the Y valve electronics as I can get hold of the honeywell replacements quite cheap.
Can you let me know if its possible that this is the problem if its sticking or will this only be an issue if the heating had to stay on, after it was turned off?
Do you have...
Thanks - is that the wiring for the programmer (in the centre)
Im a little confused with some of those steps - not sure what it refers to with TB6 TB Orange Wire, TB7 MPV, etc.
The other ones are obvious (Rstat, Cyl Stat, etc)
Thanks
In that case definitely nothing there unless its somewhere between floorboards inside the house (which I expect its not otherwise it would defeat its point?)
Is there any way I can test the Y valve as I understand this could be causing the problem? Or is this not the case if it randomly...
The boiler itself doesn't have frost protection as far as I understand but it could very well have a frost pipe thermostat as the boiler is installed in the garage.
Any chance you could tell me where I would expect to find this and what it looks like?
I haven't been in the garage for a while...
Hi,
I'm not too sure I'm afraid as we haven't moved in yet but I will certainly keep an eye on it!
I will try the thermostat if it kicks in again to see if this stops it.
Its a Y plan system - is it possible that the problem is with the Valve (a Honeywell sundial Y plan valve?)
If it...
Hi,
I have recently purchased a house and I have sometimes noticed that despite the programmer having both the HW and CH turned COMPLETLY off, the heating randomly fires up sometimes and heats up the radiators for 30 mins-1hr. The circulation pump also comes on and stays on for the overrun...
