when I wire direct into the wiring centre I cut each individual wire, so you will have 5 stubs of wire still connected, and replace one at a time makes it a lot easier and you wont get mixed up what went where

not the CH valve no, more likely a setting somewhere that you have altered when testing

I had the power off when I inspected the valve yesterday and my control unit has battery backup and it kept all the settings when I restored power and I saw the hot water light come on at the programmed times. I advance the hot water this morning, but after an hour there was still no hot water despite the CH on and working.
is the HW zone valve opening ?
Then you will have to get the Multimeter out and see if you have 230v between the brown and blue wires on the valve
