Thanks for the reply. Yes I am wondering now if that is the issue - it seems the most likely. All six wires come out of a small hole in the corner of the switch recess and it's virtually impossible to tell which go with which. I thought I had got it right but the evidence suggests otherwise...

Hi, A couple of days ago I bought a new two gang light switch as a replacement for a slightly tatty hall switch. The old item was wired L1 (brown), L2 (grey), L3 (black) for both switches, as you would expect. The new switch is of the L1, L2, COM type. So I wired L1 live into COM, L2 into L1...

Thanks Meldrewsmate, I appreciate the response and that is very helpful. I didn't realize that I actually have two zone valves in my CH topology, and I wonder now whether it is the second (made by Danfoss) which is the problem. The Honeywell zone valve located above the pipework and it seems to...

Hi there, Just a brief update. I've been monitoring my boiler/CH system over the last few days, and in particular listening to the zone valve. The system started working perfectly again about 3 days ago, with the boiler returning to '0' shortly after the programmer finishes its cycle. And...

Thanks. I'm going to give the area a general clean as it is full of dust. I've noticed that there is a lever on the back of the valve housing - I presume that this isn't a manual override but something else? And I should leave it be?

Thanks Ian - presumably there is no way to fix it through maintenance ... it's just a simple case of replacing it?

Hi, Thanks for the reply snb. The central heating thermostat is made by Danfoss. I couldn't see any red light. From a quick Google image search, the part appears to be as follows: RET230P It is located in our hall, which is just outside of the kitchen where the programmer and boiler live. I...

Hi there, many thanks for the response - appreciate it. I was able to identify a Honeywell Stop Valve, part number 272848. There was also a part made by a company called Danfoss, but I couldn't find a part number on that.

Hi, I have an Ideal ICOS HE15 boiler which has been regularly serviced and worked fine for around 7 years. It still works fine its function as a water heater, however the central heating system as a whole has recently developed an odd quirk, namely that the boiler still continues to burn gas...
