    I have tado AND came from Honeywell, albeit a different stat to you. Did you go through the tado guides; for me I put in the model of the boiler, the stat and the wireless receiver and it walked me through step by step, with pictures.

    If your only struggle is working out what wires go in to what terminals on the tado, their guides will definitely help you with that.

    Thank you very much. I used the tado instructions and it worked like a charm. Was panicking as i had never installed anything like this and had no prior electrical experience :)
