IME if you start doing any 'zoning' with the EvoHome system, driving
temperature differences of say 21C in a room and 17C in the hall next to
it, then this feature will also kill the heat every time you open the door
to that room.

Fine if all the rooms are set to all the same temperature but this rather
defeats the purpose of the exercise!

The self learning features also get as royally confused by door open/door
close, weather comped flow temperatures, and incidental gains as you'd
expect.


I recommend you buy an Evohome system and install it in your house.  You

I'd use the Danfoss LivingEco stuff as 'the benchmark' myself but yes!


Also these where mounted at high level:

(there'll be a set going into my place and getting instrumented in due
course)
