Hi,

I've bought new thermostats, but Tado don't provide install instructions to switch from the existing Therma thermostats as they aren't recognised by the online tool. Rather than wait 4-5 days for tado support I thought I would try here first.

Wiring into existing thermostat attached. Not using with H/W

Any ideas?

Thanks 😀

    I have this exact same Therma thermostats - TQX0027 - after following advice from other users in the forum I found I had the following:

    Therma Thermostat - 3 wires connected as follows:

    1 - Live

    2 - Neutral

    5 - Normally Open


    I mapped these on the Tado to:

    Live Wire - Com (Common)

    Neutral Wire - P1 (Parking)

    Normally Open (also known as switched live) - N/O


    Hope this helps.
