Hive Wiring - S Plan Problems

[RusDIY]

Hello, would be glad of some (simple, I think) help.

I believe we have an S Plan system with 2 valves - one HW and one CH. Currently the thermostat is separate with a 3 core plus earth wire and the Lifesytle timer backplate looks like the attached picture - i.e. only the HW and CH 'on' wires present.
How do I connect the thermostat wiring to this backplate to make the hive work correctly please?

Very much appreciate any help.
Thanks.

I've now realised the problem.... I hadn't closed the circuit and joined the thermostat loop. Sorry, so obvious. Still, may help someone else.

Just remove the thermostat and close the connections so that it is permanantly on. Hive does the rest.

Not only is the CPC (earth wire) being used as a live conductor but it even has a green and yellow sleeve on it - against the regulations and very poor practice.

If you have a wiring centre somewhere - near the boiler? - then the Hive should be fitted there, the wiring done properly and the thermostat cable disconnected.
