Satchwell LT25 to Flomasta2923G

[Panelman]

Hi, can anyone please help?
My old Satchwell LT25 room thermostat has 6 terminals 1-5 plus an Earth, but only has 3 wires,
Brown to 3
Blue to 1
Yellow to Earth..
The Flomasta 2923G wired digital non programmable thermostat has:
NO - Call.
NC - Satisfied.
COM /LIVE.

What goes where please? Freezing. Brrrrr.

Good evening panelman,

Do you know on the satchwell which is the switched? I’m guessing 3.

So 1 from Satchwell (if live) to Common live
3 from satchwell to N/o
Earth to earth
N/C should be switched inside the Flomasta

Thanks for that I'll check tonight.
