Hi mate, sorry for the late reply, I have been away over the bank holiday weekend :oops: I have just tried your test now, and even with the 907 set to 5 degrees and the TRV on full, the minute you push the heating on constant on the old honeywell timer it comes on :x Turning the temp...

I have the hot water come on every morning and every night and I can assure you the radiators do not come on whatsoever. So I suppose that is one good thing then? :)

Why would the rads heat up with just the hot water on? I'll try this tonight and let you know. Thanks for this mate, you are being a massive help :D

This is exactly what I have done, but it still fails to switch the boiler when the target temperature is achieved? Does it matter that I have the TRV's set differently?

Sorry to be a pain with this, if you look at this thread - http://www.avforums.com/forums/showthread.php?t=702458&highlight=thermostat&page=2 it gives you the info I was given to wire the thing. Probably wrong? Cheers

I haven't, I use the Honeywell in the dining room for timers, and the C902 in the hall purely for a digital thermostat that looks good :D My plan was to use it as it was intended come winter and just leave the heating on constant in the dining room, when I get this damn to work!

No mate, I have replaced the thermostat, I have a timer in the dining room. It has directly replaced an old dial thermostat on the wall in the hall :D

I have a very old oil boiler, but it was serviced in Feb this year and the guy said it was running well at 82% effeciency :) The hot water was not on @ the time?

It is wired exactly as the instructions state?

We had our hall decorated in April and I replaced our old thermostat with a Honeywell CM907, mainly because it looks good :D What with all this rain and it being 9 degrees here tonight I thought I would be the heating on for an hour seems as though it hasn't been on for over 4 months. I...

Cheers for the reply Steve, much appreciated. In response to your questions - The switch in the utility is just a plain old double wall light switch, one operating the outside lights, the other does the kitchen light. The way it worked before all this hassle was - If you approached the...

Yes, when they were first wired up and they were on constantly they were double checked and had to be re wired to the switchable, but still no change? It is very annoying as you can imagine :evil:

There is no other switch that I can find in the house, and believe me I have looked everywhere! All I have done is replace the PIR's, where the old one's worked perfectly up until a couple of months ago? I have tried turning the main power off and then just leaving them but it still stays the...

Anyone?

This is exactly my problem (I think)! I spent ages flicking the switch though and its still the same, on all the flippin' time!

I'll just add that the system has been in place for an AGE, hence me replacing the PIR's, now I cannot get them to go off, and yes all PIR's are set to the minimum time :lol:

interesting......

Can someone please help me with this, I am having a nightmare trying to suss what is going on with these :evil: I have got 3 lights around my house, each with a sensor on. I have had trouble with them so yesterday ALL the sensors were replaced with new one's. There is a switch in my...

Thanks for the reply breezer :D It is a fairly large lounge and to be totally honest, the room still isn't that bright with the 10 fitted :roll: The 2 in the fitted units will only be 20w IIRC, I doubt Neville Johnson will use 50w in an oak unit? I may go for 1x 1000w dimmer then...

I am in the middle of totally revamping my lounge. I have put the plasma on the wall etc and I'm having fitted cupboards in the alcove's either side of the chimney breast which the plasma hangs on. I have had 10 small 50w downlights fitted in the ceiling. My problem is this, I have one switch...
