apologises mate forgot it was a combi , those wires are just a make and break circuit , on the circuit board theres normally a link when there’s no thermostat fitted , so when one is fitted the link is removed and it’s wire in and wire out, so indeed the 2 x wires is correct , need to make sure what the voltage is, some are 240 or voltage free
plus here’s a Honeywell wiring book

hope that makes sense , this was the one I was thinking about, alas they’ve updated since I was fitting thermostats

or the T4 , can get it wired or wireless
hope that helps
Great minds think alike that is exactly the same stat as i was going to suggest last night but found Honeywell had up dated all there stuff thats why i was suggesting the t4 as being battery powered its just a make or break relay for the two wires.
And whilst doing this i checked my programmable stat and now the times are all to pot i cant change the time it gets to 10am then jumps to 0.00pm looks like i am going to be buying a new one ow but they have changed the design
