Hi there,
Firstly, I am not a plumber, but took the plunge and I have managed to successfully install a dual channel hive heating system to control the downstairs heating and the hot water, but have come unstuck when trying to wire in a second single channel controller for the upstairs heating.
My problem is that the previous thermostat/controller only used 2 wires and there are 2 other wires poked back into the wall because they weren't required, but I can't figure out which to wire where on the hive back plate. I have a brown wire, a grey wire with a brown sleeve, a black wire with blue sleeve and a yellow and green wire. (Photo uploaded)
Any help would be really appreciated!
