Hi all,
Upgrading my central heating controls from a Honeywell st669b to a hive system and getting a little confused about where a particular wire goes. Know what is needed in the wiring centre to remove old dial thermostat but there’s a wire labelled common in current programmer that I’m not sure where to put. As it’s bridged over to permanent live do I put it in there with the current live?
