Dual stat and 2 port valve on Y-plan system

[dbm]

I have a new unvented cylinder installed and have just reviewed the work of the installer. It appears that electrics to the 2 port valve driven by the high limit side of the dual cylinder stat has not been connected and hence the 2-port valve will always remain in an open position.

Is my installation dangerous without this addition 2 port valve operational?

The rest of the system works.

Many Thanks for any help!!

If you are sure it is wired like this, then yes, there is a potential danger, as the valve is not going to shut thereby removing the source of heat in the event of a boiler/control malfunction.

This should have been fitted by a G3 qualified installer, to the wiring diagrams supplied in the MI's and notified to building control.

Thanks Gas4 just confirms my suspicions.

Found out now the installer only Corgi qualified and not G3. Is there a register of G3 qualified plumbers anywhere? I'm based in the North West and now need to find someone to correct this.

Anyone know a qualified G3 working the NW ?

Cheers.
