Boiler Wiring Problem?

[Gazza855]

1 week ago had new baxi solo 24 condensing boiler fitted. Kept existing control panel on wall (british gas model UP1) and thermostat/roomstat in hallway. Heating enginner initially wired up the control panel just to get the system working but it needed wiring properly - so he sent an electrician out a few days later. Had problems the very next day!

Problem we are still having:

1 We leave the system is on timed (for 24 hrs a day) and control house temp by thermostat. Thermostat was put at 10 degrees (below the ambient room 'click' on the thermostat - which is about 16-18 degrees), but the heating STILL comes on.

2 When the control panel is cycled through timed/once/on and finally left on off, the heating system STILL comes.

3 The hot water timings appear to be working with no problems.

At other times, the heating function/thermostat seems to work fine, but then for no reason, goes 'wibble' and heats the house when either off or below the thermostat click. The enginner is going to speak to Baxi and his electrician and someone will come back at the end of this week. I think that 'they' think we don't know how to use our controls - but have been using them with no problems for last 3 years.

Really appreciate your thoughts.

probably crossed wires

or sounds more like a sticking motorised valve.

Its funny that you mention a sticking zone valve . i have just got back from one of those this morning.

Has the heating motorised valve been left with the lever in the Manual position??

probably crossed wires

it seems to me that the electrical wiring is incorrect to select its funtions for the clock programmer and the person who wired it up has no knowledge of wiring y plans / s plans or any heating devices what we need to first is astablish what type of heating .or hot water system we have and what type of valve has been installed also has a ten way box with a fused spur been in stalled to the bs 7671 regulations this job is a dodle should have any problems selecting funtions of a programmer if its wired correctly .
