Controller connections, changing from Danfoss to Honeywell

Its ok, the Honeywell can cope with anything from 24v to 240v, besides the unit is battery powered all you are providing is the switch from the boiler output (Ls) to the boiler return (Lr). It doesn't use the boiler output to power and run the clock and all its functions, this is done by the batteries.

Just connect Ls to A and Lr to B

Hope this helps

Hang on there a minute nothing I have said is incorrect:
Its ok D_Hailsham i'm not expecting any flowers or anything.
I was not querying anything you said. The OP seemed to be getting confused, particularly over neutrals and common, e.g:
sludd said:
BGEngineer suggests that the Honeywell terminal A is COM (neutral I assume) while D_Hailsham suggests this same terminal is Ls (which I assume to be constant live, looking at the boiler manual)
So I thought he needed it explained in more detail. ;)
 
Thanks guys

all hunky dory with new controller - both your help has been invaluable
