Replace drayton thermo with wireless

[Rab]

Looking for a bit of advice on changing my old 3 wire drayton dial thermostat to a wireless thermostat that came with the new water tank we had fitted.

Do I just need a permanent live and a switched live for the new setup?

Unfortunately it won't let me put pictures up.

Any help appreciated.

Do yourself a favour and stick with the hard wired stat. Wireless stats appear to be sexy until the batteries run down and you havent got any hot water. Just my opinion

Really? I thought it was just a natural progression type gadget.

The reason I want to change the drayton dial is it doesn't seem to work very well. Doesn't seem accurate.
And I want to move it into the living room as the kitchen never gets up to temp and the boiler ends up short cycling possible due to overheating.

problem with moving a stat is that you would need to replace your trv with a lockshiled valve in the room you desire to move the stat to,

and also if its a small room you would need to keep a few doors open as once that room is upto temp the heating will turn off even if all the other rooms are cold

That's the thing the radiator in the kitchen has a trv and the living room doesn't so that's what makes me think it should have been in the living room to begin with?

The kitchen Is quite drafty due to the cat flap so it never gets up to temp.

could of been unless someone has replaced a lock with a trv

 

[Rab]

Possibly. I think this property's CH was put in as part of a government scheme 12 years ago long before we had it. The plumbing is nothing short of shocking. I'm guessing they were in here for a day then ****ed off.

All the pipes were run down the walls inside electrical conduit ha.

The thermostat was probably put in the easily place they could access

 

[Rab]

Btw the kitchen is the same size as the living room

Sorry for all the photos. Far easier than explaining.

 

[ShaunCorbs]

does it require mains or does it run off battery's ?

what model dryaton is it? (new)

and not a problem

 

[Rab]

The sender will be mains using the old thermostat wiring hopefully the receiver is batteries.

The new one is a celect controller. Never heard of the make before mind.

Any thoughts on wiring up the new one. I was thinking live to L (power) and switch live (yellow) to S1? And just tape up the neutral.

 

[ShaunCorbs]

dont think its going to be better than the one you got but

red to com

yellow to nc normally but depends if open contact when no power

 

[Rab]

It's worth a shot you not think? I did get it for free after all, maybe that's why.

Can you recommend a better thermostat?

 

[ShaunCorbs]

upto you

and i would go with a Honeywell DT90E

 

[Rab]

I'll look into chief. Thanks for your help
