Tado Wiring

[neilrussell]

hi there, first time poster - be gentle

Just trying to figure out the Tado smart thermostat wiring from our current system, which I *think* should be simple, but wanted to be sure as the Tado setup site didn't detect my setup.

We have a ferroli Modena 27c HE and a Honeywell t6620b thermostat.

It's wired thus :

live to A and neutral to B.

I'm not sure how this translates to the Tado NO / NC / COM

Can anyone help?

thousand of thanks in advance...!

Brown to COM, blue to NO.

Rsgaz is correct; but you are not correct in calling the blue wire the "neutral". It is the switched live and should really have some brown or red sleeving round it at both ends. So far as heating is concerned, you should never assume that wire colours mean what they normally mean.
