It is connected problem that I describe minutes ago in different topic, please read it
and that is way I've 11 thermostat schedular, when I've tried to set one temp on few trv at one time - it doesn't work (as described above) so I've created 11 scheduler with 1 minute delay between and it works. But when I want to use "away" option built-in thermostat scheduler it doesn't work because HE try to change temp to away on every trv at one time and right now it is a problematic and that is why I need to do it trv by trv not at one time.
Hope that now is clear
