Hi, after some help wiring up the Tado Extension unit to my boiler. I have attached some photos of the existing wiring, the wire supplied form Tado and instructions from Tado and those on my boiler. I'm assuming from this I need to remove the existing bridge from terminal 1 and 2 and attach the grey switch wire to Terminal 1 and the live brown wire to Terminal 2? Then what about the blue Neutral?

Any help appreciated.

Ive not got the Extension kit, but do have the Bridge & two stats.

Not sure if you are trying to wire it up before setting it up with Tado, but from memory when you go to add the device to your account online it asks you what boiler you have and provides a full guide on how to connect it with pictures.

If you haven't already looked at this, hope this helps.
 
Yeah, it replaced an existing wireless receiver originally and I used the instructions to follow. I've recently had the boiler moved as part of renovation work and need to install the receiver like new but the instructions they have sent are basically just like the picture attached

I'm familiar with many domestic extractor fans which are primarily class 2 (double insulated) and consequently are not required to be earthed...

3 core wouldn't, but 3 core and earth should I think. The live from the UH4 could feed both the brown and grey of the valve.
