Thermostat overriding the programmer?

[matt1e]

Looks a bit of a mess but looks as though it should work the way it is, are you saying that with the room stat up and ch off at the programmer
the central heating is still running?
if so undo the top terminal of 9 and pull out the red link, if the central heating is now off then you need a new programmer as its relay is stuck closed

Excellent sounds like that's the solution. Any recommendations as to where to get it from?

Shop around but Plumbnation are usually good for price.

Your pic fill 2 x 23" screens

Thanks - well I wanted it to feel like you are there (with a magnifying glass)

Yup that's exactly what I'm saying. CH programmer says "OFF" and it still runs if the thermostat calls for it.

I'll try taking out the red link of number 9 later and see how that works. So if that's it and I get a new programmer does that mean I don't have to run downstairs every morning freezing my *** off?

Matt1e - I have taken out the red link at the top of 9 (thermostat does not show power) and turned the programmer to turn central heating to "ON" - and nothing is happening.

So is that as you guessed?

Yes, you need a new programmer

Okay thanks. If I get the same model (just for easiness) is it an easy enough task to just take off the duff one and wire the new one up as per the images on the previous page?

 

[matt1e]

You wont have to wire it as it will fit straight into the existing back plate if you find that easier (I personally would fit the new back plate though).

Just a thought though, the heating wasn't still working with the programmer off the backplate as per the photo was it?

Matt

 

[skeggz]

Yeah in that photo the heating was still working even when switched to "OFF" (as long as the thermostat was asking for it)

I'm talking about this photo?

 

[skeggz]

Yeah that's right. That's how it is now and central heating comes on even when programmer says 'OFF' and thermostat is turned up.

 

[matt1e]

but the programmer isn't attached/connected to anything so what difference does switching it off make?

 

[skeggz]

I didn't know the central heating programmer wasn't attached to anything

So can it be wired to get it how I want it?

 

[matt1e]

we will start again from here mate and then I will read the thread again
First question, what is this a picture of?

 

[skeggz]

The wires after taking the face off the programmer.

Right, now with the face of the programmer taken off as per the photo (this is what I meant by the programmer not being attached/connected btw)

did the heating come on when the room stat was turned up?

the answer should be no,
