I have twice spotted today that, having selected the Heating Quick Action - Off Mode, when the Hot Water timer triggers the DHW relay on, the CH relay also turned on.
This suggests to me that the controller software is not functioning correctly. If CH heating is in Off Mode, surely any command from the controller to DHW relay should only trigger the DHW relay.
This setting on the controller is not a normal setting I use - hence having just noticed this anomaly.
Has anyone else seen this situation? If not, I am wondering if there is a wiring issue. Both BDR91s are wired into the Honeywell Wiring Centre so maybe a live is feeding back from the DHW BDR91 to the CH BDR91. This I will check but if others have observed the same issue, the software needs a fix.
