Thermostat

[martint235]

I'm fairly sure my thermostat isn't reporting the correct temperature so it thinks the room is warmer than it is. So

• How do I fix it?
• Is the backplate specific or will it fit other thermostats?

I've changed the batteries and checked for excessive dust in the vents

TIA

Why not set it so that the room is at a temperature you want, irrespective of the number shown?

If it's just misreporting i.e. It shows 21 when it's actually 17 and 22 when it's 18 etc that would be fine. My worry is that it doesn't know how "big" a degree is anymore and could end up costing me, or more accurately the missus, more in fuel bills if that makes sense

Is it inaccurate or merely reporting the temperature at that particular location? The thermostat here is located in a place that is warmer than the man living space.

Trying to get to grips with the one in the house we've just moved to. There's a wireless room thermostat and thermostatic valves on the radiators so I don't think that's ever going to wrik properly. I think you're meant to just set the water temp (and timer) and let the thermo valve sort the rooms out. The room stat is also the timer - which I do need so can't just ditch it.

It "hunts" as well which is annoying

It is in a warmer place but this morning it was reporting 20c , there was nowhere in the house close to that.

That's the thinking behind the second question. If it's interchangeable I can do it without messing with mains electric.

I may just pluck the courage up to play anyway

Why not just get hold of a cheap thermometer and leave it on or by the thermostat? I bought a couple for about a fiver in the high street and worked out the difference between degrees Celsius and degrees Deptford.

Now that's an idea

I don't need you to leave any of your bikes to me in your will.

I doubt they would fit you anyway.

I replaced the thermostat in the hall with a new one that I got from Screwfix for not very much. It was pretty straightforward, and I speak as one who's not very good at that sort of thing.

How do you know its the room thermostat thats wrong and not the thermometer (presumably) you're comparing it to?
Unless you're comparing it with 2 thermometers and going with the majority of course.

Actually, I reckon you'd need several, say a dozen, or more,to make sure you've got a really accurate result.

You'll need to get the results of your investigations peer-reviewed as well.

How about dumping the current thermostat and splurging £11.64 on one of these?

You won't be able to see what it's doing on your Garmin or phone or whatever. If you want your place to get warmer, you turn the dial clockwise. Cooler, turn anti-clockwise. Retro-chic or what!

A basic mains-powered room thermostat is effectively just a switch; in theory it's very easy to replace.

Off you go to screwfix with your catalogue, and return with a nice new stat. You congratulate yourself on the excellent price, knowing that you're saving a fortune in plumber/electrician fees by fitting it yourself.

Then the problems start .

1) you're not quite sure how to isolate the power so you switch off the entire fuseboard. The kids clatter down the stairs complaining "the internet isn't working". SWMBO tuts and says "I was going to watch The West Wing" (or whatever box set it is currently). Tick tock, get on with it!

2) The old baseplate has to be discarded but sticks to the wallpaper causinga big unsightly rip. SWMBO rolls her eyes and mutters something about redecorating.

3) the wires won't reach the terminals in the new baseplate, so you have to strip the wiring back (making more mess) and fit the new baseplate higher on the wall, leaving a distinctive 3x3inch square of unfaded wallpaper just below.

4) the cordless drill that was rubbish even when brand new, is now completely useless having spent spent the last 17 years gathering dust in the loft. Back to Screwfix to buy a replacement. That Ryobi model looks nice, well worth the cost considering all this DIY I'm doing, you say to yourself. Suddenly you've blown the budget; it would have been cheaper to get that plumber in.

5) You accidentally drill into the wires whilst fixing the new baseplate to the wall, and end up having to replace the wire all the way back to boilder. You wish you'd bought the wireless thermostat now.

6) The screws won't do up tightly, so you try drilling another hole only for the plaster to crumble away. Off to B&Q for some "deep gap filler".

7) Done! (just the redecorating next).

Nah you missed the bit where I end up having to call the electrician out anyway
