How to connect?

DennusB

Hi,

Currently i have a Nest V3 connected and want to replace it with a Tado. See attached info for how the Nest is connected.

If i connect the T1/T2 red/blue wire to Tado on COM/NC it should work right?

Regards,

Dennis

Simply turning up the temperature on the smart thermostat should bring a slightly belated noise as the 'switch' operates (need to be close to the stat to hear it) followed by the firing of the boiler.

Need to add that the boiler should be set to heating on permanently. No sure whether you are combi boiler or not if not then hot water through the extension kit.

@DennusB I had the Nest bridge in my set up so was slightly different but finished up with t1/t2 wired to NO/COM not NC/com. Have you not received full wiring instructions from support?

@samd Thanks. I haven't received any full wiring instructions from support actually. I was trying to fix it myself haha.

@DennusB No probs - good luck, ask away if any help needed - there are some experts on here!

@samd thanks! Just checked and it’s now connected to COM and NO as said by you. Is there an easy way to check if this works?

Hi
I am looking at exactly same swap?
Did you connect wire from 2 and 3 to COM and NO?
That's it? What about the cable positive and Negative in the nest. Shall I not connect these in TADO?
