Replacing thermostat help

Myser

To check the connections, first switch off the supply to your heating controls.

Loosen the screw at the top. If there is just one cable i.e. with a brown, blue and possibly yellow/green earth cores with the earth unconnected or terminated into a blank terminal, you have a two wire thermostat.

Perhaps take a picture with the cover removed and post it on here.

This link may explain what an anticipator is better than I can:

I haven't got a clue! It was here when we moved in.

Looks cheaper and older, no fancy switch on the side like the one in the link, just the temperature dial with Wickes on it!
How do I know if it's three of two wires?

Just take the outer off and have look how many wires are coming in. I assumed (rashly it seems) that you may already have done so in order to be able to say that it is like the Wickes one. Exactky how it works internally isn't irrelevant and a distraction - a thermostat is only a switch at the end of the day. Just do a like for like replacement electrically and it should be fine.

Another option you may want to consider is a digital thermostat. They are little more expensive but you can also see the current temperature.

It has two wires that are hidden and one additional one that looks like an earth as it's further away. Is that two or three wires thing that I need to get? Won't be going to Wickes, OH off to Homebase as we need some building stuff and they do 20% off.

As far as I know the thermostat is disconnected from boiler by my gas guy (moved the boiler recently) - how do I reconnect it when I get a replacement?
Maybe I should email him... Happy Christmas and all that... so how do I get the thermostat back on lol

Seems like you have a standard two-wire thermostat.

If the thermostat wires have been disconnected and bypassed at the boiler, it will be a bit more trickier.

If you aren't familiar with boiler wiring, it's probably easier to call in someone to do it for you.

Nope, have no idea with boiler wiring at all. Anything to do with it is beyond me, the damn thing scares me tbh.
Turned the water off the other day and after the boiler wouldn't work. Somewhere far deep in my brain I remembered the gas guy telling me to turn some valves... so pulled that off, not really sure how.... Might have to send that email after all. He seems to think I know stuff :rotfl:

I assumed when you said disconnected from the boiler, you meant at the boiler.

If the connections have only been bypassed at the thermostat, that is easy to remedy.

Have the two (brown and blue) wires been joined together at the thermostat?

The thermostat looks connected (no loose wires), so I think it is disconnected at the boiler. Guess that's more difficult to fix...

Time we turned this thread off then. No-one on here can see it physically and so any step by step advice may be confusing and worrying to you. You should get someone in to it. I think you'll be more comfortable that way.

Thanks for your help Keystone, yes I will email the gas guy. Guess that's the best.
