Hi Everyone,
Was looking for some advice on the below. Boiler is working and controlling the heating however the hot water diverter valve is not talking to the nest and has been put onto manual override which is causing the hot water to be permanently on and extremely hot. All new parts as new install.
Components of the install are:
Problems:
Existing Wiring:
Boiler Wiring picture attached
Looking at the design wiring plan, I think that the boiler should be the lead power and that there should be a Live return to the boiler to control the switches however this doesn't appear to be the case on the actual wiring.
Also I think that there should be some control of the cylinder temperature in the boiler but again there doesn't appear to be any cables connecting the cylinder temp sensor to the boiler.
Appreciate this is like an exam question, however Im trying to resolve but need some advice.
Thanks in advance
Pete
