Having some problems with hot water control now.
I'm aware of the change to hot water priority and earlier in the day I tested a couple of hot water reheat cycles and they worked as expected - with hot water priority.
However now my hot water won't reheat at all. I turned the bathroom radiator up to 23 (current temperature about 20C) and started running a bath. Within a few minutes the temperature dropped low enough to trigger a reheat and the icon on the home screen indicated that it was reheating the water but it is not.
This picture was taken about 10 minutes in and it can be seen that the hot water temperature has dropped to 16C, the icon is showing it should be reheating, however the system summary page is not showing 100% boiler demand despite hot water showing 100% demand:
Furthermore, my boiler relay is only cycling on intermittently, (as the low boiler demand indicates) the heating relay is still on and the hot water relay is OFF.
Another 10 minutes later the hot water relay still has not come on so the hot water is sitting at 16C and no attempts are being made to reheat it.![]()
