Thanks for the prompt really, already been a million times more helpful than Honeywell support!
But a bit confused as I thought it would have been the other way around, as in swapping out the existing programmer and decommissions the Drayton as doesn’t look like that controls the hot water?
Hi,
I was given a Honeywell Lyric T6R-HW Thermostat and wanted to install at my parents as I already have a hive system. Haven't done a self install before, looking for some advice - attached are some pictures of the set up. Firstly, would the T6R-HW be compatible? Secondly, if it is am I right...
