Moving a thromostat

[OlafIrolp]

Hi guys... i am moving a thermostat which is placed near a front door. It has two wires Brown to "L" and Blue to "3". It is a drayton combi-stat to a biasi combi bolier.

First of all is the wired correctly?

Second i have some new cable about 1.5 i think with Black, Gray and Brown + earth in? Which ones to blue and brown so not to be confused if any one ever wants to replace it. I need to extend the exsisting cable. I hope all makes sence.

Thank you for any advice.

Yes it makes sense, get an electrician in to do it so you know it is safe.

if its that easy why cant he do it??

 

[trev]

A sparky will know what to do mate just like my learned friend Cagedanimal2010 suggested

 

[OlafIrolp]

because its got to be chased into wall... also there are only two connections to make

please im asking for advice here on cable type? i have 3core notmal housing circuit types..

 

[telectrix]

the 3 core cable yo have will do the job. but from reasding posts, you need to get a qualified sparks in to fit.

 

[OlafIrolp]

but how come? diconnect move th thermostat and reconect... your just extending the cable... which goes through the loft... i will get someone if i feel is right but i kinda agreed with the heating guy. the walls in my flat are v solid not soft.... he said "do you want to chase that?" i agree for the sake of moving a stat is abit of mess/pain why not just live with it next to the enterence.

 

[trev]

A thermostat usually has a permanent live, a switched live, a neutral and a CPC, maybe that's why you need a qualified electrician mate. It does not matter whether it's chased in or not.

 

[OlafIrolp]

yes ... ok ill chaase out the wall tomorrow and call some one... i noticed it was reading about 2 degree below actural room temp... but only had two wires inside... sorry id like it chased... it started to niggle me.

 

[trev]

Why are you moving the stat? It's supposed to be in the coldest area of the house isn't it

 

[OlafIrolp]

im conviced its not working properly.... plua juat seems to be in silly area people coming in and out draft

 

[OlafIrolp]

ok i have chased out put cable and truncking in and re-filled...

What do want a medal? Sounds like a never ending story

What makes you think it isn't working properly? And, when you consider it was most likely installed by an electrician working on instructions from a heating engineer why do you think it should be in any other position than the one it is in now?

 

[OlafIrolp]

just seems to read to low... for example of you keep it on 20.... it will never turn off

Could it be that you've now got it in a position where your heating is struggling to raise the temperature enough to turn the heating off??

 

[OlafIrolp]

thats what the heating engineer said... it near the front door... which is acturally seems to far away from the main area of the hall... got to remember the hall only as a smaller single rad also.... from what i guess as long as its not near a radiator or door you can have it anywhere... he was suprised as it next to front door and not really in the main area.... i dont think it works... like i said if reading low it will never turn off?

to add to that i came in the flat a few times and central heating was runner... mesuring 0... at the time it was v cold bet not freezing inside? it might be just me bieng a worrier... but never seemed right from day one.

heating guys says jusr live with it its and on/off switch...

Hi the stat is sort of wired wrong!!! Most modern stats need a neutral to work accuratly all you have is 2 wires so basicaly you are just switching a timed live! Aaron

Not always on this one mate the drayton stats can work on 2 wire and do not need a neutral probable cause of it not switching off is the area is cold so the way to check it is to turn the stat down and see if it goes off

I hope there isn't a thermostatic rad valve on the hall radiator? If there is, make sure its turned up to max or remove the head.
Very basic I know but I've seen it happen!

If it is turned up to max then the room would be hot and the thermostat would not operate the boiler/pump as it is telling it the room is at the correct temp.

Could also be an airlock in the pipework thus hot water not gettig around system

Dare I say time to call in a heating engineer/plumber!!

lol

 

[JohnBoyZ]

Just to clarify, I meant turn the rad valve up to max (not the room stat) the room stat has control of the hall temperature.

I thought he already had and it was him that said move the room stat.:svengo:

 

[OlafIrolp]

He did but I got it done.

Why couldn't you just turn the roomstat down a couple of degrees and monitored temps, so that if you want say 20 degrees In living room you could turn the stat down to 18 degrees and check temps in living room. Then adjust accordingly.

I hope this makes sense.

I wouldn't have put the roomstat beside the front door in the first place.
