A neighbour asked me to connect up a Hive wireless controller.
Seemed easy enough, it uses the same standard back plate and connections. Straight swap there… and disconnected the wires going to the room stat, and linked through in the wiring centre.
That was before I went on holiday, and now she says the heating only works when water is on.
I’m going back to have a look, and I really should have taken photographs. The outgoing lines from the controller (x2) are as they were.
Plumbing side, it’s a system boiler, hot water tank and a mid port valve. I’m guessing the valve is stopping mid point when it should be fully over to heating only.
The outgoing lines on the controller plate are N, L, 1, 2, 3, 4….
What should they be connected to?
I’ll check when I go back
It might be as simple as being the wrong outputs needing swapped, (heating and hot water) but if so…. The old controller must never have worked properly either…. I didn’t actually disconnect anything from the plate.
