Is there any advice on using Honeywell Evohome with 2 zone heating. Honeywell support are pretty useless and give conflicting advice. They suggested I ask my installer (but my installer suggested I ask Honeywell). I found a support article on the Honeywell Resideo website by Googling "How-to-control-more-than-one-heating-zone-valve-with-evohom". This seems to suggest binding the two port valves (which is not what I want to do).
Ideally I would have HR91 Radiator Controllers on some but not all rads. This doesn't seem like it is supported. I'm not even clear if I can have HR91 Radiator Controllers on all rads in one zone but not the other.
If Honeywell Evohome does not support dual heating zone systems well then does any other system?
It seems worrying that Honeywell don't seem to have a clue how to support this given the fact that Building Regulations Part L 2010 mandate two zones. Even if Evohome makes two zones redundant, it does not seem sensible to tell people just to bind the zones.
