No need to be puzzled, I know the basics, but just want to be sure that I get it the right way round, as rather not knock out the central heating for a day or so while I try to fix a false assumption. Not that warm here at the moment and wife would not be impressed!
Thanks for the input, that...
I am trying to install a new Drayton HeatHub (1zone), just trying to work out wiring as I am replacing Honeywell T40 thermostat. Images attached of exisiting wiring and new HeatHub wiring diagram.
Cheers
Jon
