Removing Old Room Thermostat

[llwynygan]

I am going to replace my existing heating system controls with a wireless smart heating system (probably Drayton Wiser). In doing so I want to remove the two existing room thermostats I have (I have two zones for my central heating). They both have three wires (as well as the earth)

1. black (sheathed in blue) - I believe this neutral
2. brown
3. grey

I believe 2 and 3 are the live and the switched live.

What do I need to do to remove this room thermostat?

To remove it altogether you need to remove the wires at the other end, if you just want to make it work, then connect live and switched together in a terminal block.

You need to find these wires in your wiring centres and then bell them out to confirm

One end / core will be in where your 2 port valve brown wire is
