Thermostat / Breezer

[Johnnee]

Breezer, you probably remember me and my thermostat from a couple of weeks back.
Fitted new thermostat, though now nothing seems to work, no hot water etc..
The clock timer that switches heating on and off etc is also not working. Have checked fuse and this is OK. Is everything connected/worked through the thermostat ?? and am I likely to have wired it wrong ??
or could it be something else such as diverter valve, as even the manual override on that doesn't work.

Thanks

it sounds like you have wired the stat wrong, even with a eletric valve stats only use two wires (not counting earth) live and switched live, you may have connected them across the wrong terminals.

There were 3 wires from old one, not including earth.
2 from 1 cable, Red and Black with earth in as well, and a single red one on its own.
Are Live and switched live the 2 red ones ??

 

[breezer]

it is debatable, but probably, since it depends on who wired it as to what they used

Thanks Breezer. When I said there were 3 from old one. What I meant is that from the wall their is a 2 core cable with red and black plus the earth, and their is also a 1 core cable that is red. I have assumed that the 2 reds are live and switched live. Does this sound about right ??
Thanks anyway, will be tomorrow before i try switching them now.

 

[breezer]

yes, sounds ok, some stats have a neutral, which is why i should assume the single red is there

 

[Johnnee]

It does say on Thermostat I bought " Gas Filled bellows means no neutral connection "
From your last message, do you mean the single core red is likely to be the neutral ??

 

[breezer]

no, the black

 

[Johnnee]

ok, thanks
