Hi there.. I've managed to get back to the house briefly and have spent longer belling out the wires. I was wrong about the above Brown wire in the thermostat. It's actually linked to the call for heat (CH On) in the timer switch.
The other 2 descriptions still stand.
Thanks
Thanks for your support. I'm struggling for time to get to the property at the moment but will hopefully investigate further in the next couple of days.
Hello RG... I'm just back at the house. The thermostat on the wall certainly controls the boiler for the CH at the moment and the wall timer works too.
There is another wireless Centre timer controller that I put batteries in and it now controls the floor heating. At least when I wind up...
Thanks for the suggestions. I'll probably go down the 'extra spacer' route for now.. The Hive arrives tomorrow, by which time I'll hopefully have checked that the 'wiring out the thermostat' has had no detrimental affect on the boiler running just with the old timer. I'll keep you posted in a...
How would I go about incorporating a wiring centre box along with the FCU since the cables have all been cut just to fit into the FCU? Can you point me in the right direction regarding what to buy? Thanks
Ohhh.. one further thing perhaps.... Is there any way I can get some bigger box/FCU such that I might be able to get all the cables back in a little easier?
So…I’ve just been back to the house and the cable from the thermostat to the FCU is wired thus:
Black wire (sheathed blue) at Neutral in the Thermostat goes to Black (sheathed blue) into the FCU load.
Brown wire at Live in the Thermostat goes to Brown FCU load.
The Grey wire (sheathed...
I've just been to the house for further investigations. Anyway, with some long cables and an old fluke I managed to check for continuity between the thermostat wires and the wires in the FCU. Bingo - The grey (sheathed brown) switch wire at the thermostat is definitely the grey wire in the...
I've never seen so many wires packed into a fused spur. The faceplate burst off when I undid the screws! Might the thermostat wire be one of the incoming from the above trunking?
