This is just superb - thank you so much! One suggestion to make it even better - how about introducing a dynamic warmup time per zone, like some systems such as Honeywell Evohome do? @tommypearse looks to have done a lot of hard work in that department here: Optimum Start for Heating Systems, or alternatively something that uses statistics from logs of previous heat up times as a guide, maybe even something that’s influenced by the weather too?
