Wiring from a Sunvic TLM2253

I'm replacing a SUNVIC TLM2253 - but I can't work out what wire goes where on my Tado thermostat.

I have two wires going into the Sunvic, plus an earth lead to the casing of the Sunvic.

The help on the Tado app, suggests I need 3 and I don't have them in the positions they think I should.

Attached is a photo - but the grey wire does have some brown sleeving on the back view.


Its a three story house with 3 zones - I successfully installed Tado on the other two floors earlier in the year.

Any thoughts would be appreciated.
