Honeywell thermostat to digital change

[Gavinc2020]

Hi

I have an old Honeywell thermostat to change to a digital type made by danfoss. Can someone give me some advice on the wiring. I’m usually good at wiring but wiring diagrams are not my thing at all.

So it currently looks like:

red wire : position 1
Yellow wire : position 3
Blue wire: position 2
Earth wire to back box.

Where would these wires be sent to in the danfoss unit shown in the wiring diagram on the paper booklet for the RET2000ms

all help is greatly appreciated.
Thanks

Blue to N
Yellow to 2

Thank you. I was confusing myself with the number of terminals on the danfoss unit.
