Good afternoon all, just a quicky.
Ona Y plan system can anybody tell me why there is a switched live from the cylinder stat back to the programmer (Also connected to the grey on the MV)?
Why does the programmer need to know that the cylinder has hit the required temperature?
FYI I installed a new nest smart stat and have never actually thought about why the programmer needs such thing.
All the best, Michael
