Better Boost Options
I was pleased to see the boast function for the system but very disappointed that you can't select the temp (25 is way to high for my house), or select to just boost one room/trv. I find that I often want to boost a room for just 10mins, and only being able to boost for 30mins at 25 is wasteful and unnecessary. I see that others say you have to boost all and then turn off individual rooms, very clunky.
Each TRV should have boost setting where you can chose your own default time and temp, plus a master one for the whole system. Rooms heat at different speeds and there shouldn't be a 'one fits all' approach to this.
