New build house 2019.
Heating works fine via the app but hot water can only be controlled via unit next to HW tank manually or set schedule.
I've opened the receiver unit and there is no wiring to the hot water (D&E) however the HW light comes on when the HW is on via the schedule so something is telling the unit the HW is on.
The photo shows a brown loop between L and A.
Any easy solution to get the HW controlled via the app or should I contact a plumber / electrician?
thanks
