Tado X wiring

Bigbuddie

Hi , I'm replacing my nest heatlink with the Tado X. In the installation guide it shows two wiring options, neither of which match the existing wiring on my nest heatlink. The two wire option shows the wires in OT1 and OT2, my heatlink is wired in OT2 and OT3.

How do I wire the Tado X?

Thanks for any help.

Yours is wired to 1,2,3.

Hi thanks for the reply, as you can see from my picture, there is no connection in No1, that's what's confusing me.

Maybe you should get someone in.
