Vaillant combi store cylinder stat problem

[davesparks]

I've never worked on one of these before but that looks like a reset button in the middle of the big shiny nut!

Are you sure you are experienced enough to be able to work on these? unvented cylinders can be pretty dangerous things if you were to do something silly like bypass a safety stat and let them get too hot! And of course they do have their own rules and regulations surrounding them.

1. Yeah I was wondering if that was a re-set when I relooked at pic
2. If it is I find it strange if it needs re-setting when it is a brand new part
3. Don't worry I won't be bypassing the stat, I just did it to check I wasn't going (totally) mad and see the system would run
4. Yes reasonable amount of experience cheers but not afraid to look silly if I'm wrong, hence the post on here, by no means a heating system specialist though
5. If that is a re-set button and I've been on the phone to vaillant technical and they haven't mentioned to try it...oh never mind

I don't touch heating, pipes, stats, trvs, anything that involves plumbing or central heating, ts a plumbers job, not mine, I don't have a clew what I'm doing. I'll be open and honest, I have no experience of heating controls.

So you are posting here just to boost your post count then?

If you are an electrician then wiring heating systems is part of your job.
Unfortunately there are far too many people working in the domestic sector and calling themselves electricians that just can't wire boilers, it's ridiculous.
And then there's the ones who think they can but get it completely wrong when faced with 2 heating zones!

It's not the plumbers job to wire and connect the controls, it is yours. What would you do on a new house that you were wiring if plumber said Im installing upstairs and downstairs heating zones and an unvented cylinder (S Plan +), would you sub it out?

Then you would be of no use to me on site...... so when it was time to connect up the finals you would just leave the heating and hot water for somebody else to connect up ???

There's nothing re-settable that I can see no

Little red button in middle of red O. Has nut around that
