Hi, I would like to install the Tado wired thermostat but I’m struggling a little, can any help with the grey and black wires? I know the brown (live) goes to COM on Tado but in my current set up the grey wire is in COM and the black is in ON. I’ve tried brown in COM and black in ON but this doesn’t switch on the heating, in fact it doesn’t do anything! Any help would be very much appreciated

Answers

  • Suggest you contact Tado for personalised install instructions. They will provide details based on your current model of thermostat

    However, if it is just a two wire unit that you're replacing, I would expect live (grey?) to go to COM and black to go to NO.

    If you're unsure, it may also be worth getting a sparky to do the install
