Hello,
Apologies if this is a very simple fix and I haven't yet found the solution.
I have a Y-Plan, open vented system with a Worcester Greenstar Ri
generally everything functions as expected except for one particular situation and that is:
If the hot water is on and I switch the heating on (manual override at timer controls), everything works as normal, but if I then attempt to switch the heating off it continues to heat the house and will not stop unless I also turn off/cycle the hot water (set to manual 'on' 24/7). I can then switch the hot water back on and it not affect the heating at all.
Its as if the hot water being on, blocks the heating from turning off.
Any thoughts and pointer would be appreciated.
FYI. I am happy to look at wiring at the consumer parts (thermostat, remote controls, etc..) but will not be going anywhere near the boiler apart from the two consumer available/allowed dials on the front of the unit.
