room stats

[mutley racers]

Hi chaps, I got a danfoss standaRd room stat. Am not getting any audibel click when turning it up or down, when heating is on, am getting 230v at terminal 4 and . Even when I turn it up and down. Is this correct? As it is not calling for heat at wiring centre. So not getting any heating. Wires are a pickle as well.

But apparently it was working ok. And then the heating would stay on with hot water but couldn't put heating on on its own. So I put new 3 port valve in and now I can get hot water on its own but not heating at all

It wasn't a spark it was I! Screwfix had red insulation tape on offer. I would defo strip it all back and re do all connections and clip it all back a little neater.

If its just heating u prob made minor error. Is stat a 3 wire or just live in s/l out?

So when hearing is on does vale engage / but no ignition on boiler? If so no juice getting through micro switch when 3 port swings to hearing only.

Also what boiler is it?

Has this boiler got an Earth connection ? Looks like just pump earth wire ?

And it looks like its not heat resistant flex. Time to rewire IMO

Well if u want to check bump that black jumper onto other rouge !

 

[dancinplumba]

Was it hot then ?

 

[dancinplumba]

Is the red live when calling for heat ? Is the black live too ? What have you checked ?

 

[mutley racers]

Yep, am getting 240volts on on both sets of wires. But if I turn stat up or down nothing changes.

Also heating on on programmer is live. But not getting any audible click from stat
