You dont get it, only pluming alterations can do this electricerty wont make any difference whatsoever
If this is the case, you will be able to control the water independently from the heating.
once the cylinder thermostat is satisfied the boiler will shut down but the pump will keep running, you cant re-invent the wheel just do it properlyShould the cylinder thermostat dictate the maximum temperate of just the hot water or both the hot water and heating?
Can you answer the question, please, before start getting ahead of ourselves.
OP is that motorised valve on the pipe going to / coming from the cylinder?
Is it a 28mm pipe?

I can feel a deal coming on here...if you can post pics of all the wiring for your system (cylinder stat, motorised valve on dhw primary, wiring centre if any and of course your programmer backplate) I'll knock up a couple of relay cards in return for you hacking the scripts to find out how I can use a Wiser radiator stat to control a Wiser DHW channel
I'm more than happy to see what is possible with your Wiser setup!
