Discuss hot water won't turn off in the Central Heating Forum area at PlumbersForums.net
I disconnected the orange wire and turned the power on. The MV still moved around and engaged the switch but the boiler didn’t fire up (I guess that’s what the orange wire does )Disconnect the orange wire and see what happens or what shouldn't happen.
When I swap the heads over and the wiring then the same thing happens. But before I changed the wires over I tried just swapping the heads. So basically to get the Hot Water is now controlled by the Heating side of the programmer - Doing this solves the issue - it works as it should - to get the MV to operate I had to turn on the HG60 and the programmer on and then the MV kicked in as normal to turn the hot water on. Brilliant! But then the other valve opens the heating valve and turns the Heating on without being asked! So must be a wiring issue? Even though I haven’t moved any wires around before the issue started? I posted a pic of the wires in the post earlierDon't know if fitting a new complete motorized head instead of just the synchron motor would make any difference or not. In the meantime suggest fitting (again) the motorized head from the CH to the HW and wire it up by removing/using the wires from the "old" HW head, let the wires disconnected from the other actuator and see what happens.
