Wiring issue

Hi, I'm replacing an hold Honeywell thermostat T6360. The instructions are great but the only problem is that on the wiring position 2 I've got 2 blue wires and not just one. They have enough space to fit in the old thermostat but no space in the new Tado, what shall I do?


  • If you really can't make it fit, you could join them together in the backbox before the Tado connection so only a single wire goes to the Tado but I would recommend finding out where the other wire goes to as it may be redundant
