I've just purchased a new house (well 11+ years old).
I appear to have a problem with the h/w stat.
Whenever the H/W timer is in a timed period the boiler is making a noise, even if it's had plenty of time to heat the water.
I have hot water ok.
Surly this is not correct. I assume a problem with the h/w stat ?
Is that the black dial ontop of the cylinder ?
It is just a 3 wire connection Com, No, Nc contacts ? Does anyone know the wire colours ?
Do the dial numbers equate to some temperature, if so, whats a good/normal setting ?
Anyone have any suggestions or common problems with this system.
Thanks very much for your help.
