Replacing Room Thermostat - 3 wires?

[jchasty]

Hi All

I'd like to replace my Danfoss RMT230 mechanical room thrmostat with an electronic programmable one.

I have settled on the Honeywell CM907 (not yet purchased), but would like to know where my wires go!

Currently, I have wires on my existing thermostat on terminals 1, 2 & 4, as below (terminals not in numerical order):

The wiring diagrams for the CM907 are below - which one do I follow?

WoW! Thank you very much for your quick reply!

I found a CM907 locally and it is now installed in less than 15 minutes!

Thanks again.
