We have a fairly large open-plan section of the house (6 radiators - 4 HR91, 2 HR92), and have also effectively run out of zones.
Consequently, this section is configured as a single zone. It's been configured as a multi-room zone, to give the radiators a measure of autonomy, and also allows the radiators controlled by the HR92 to be locally tweaked.
By & large this seems to work fine.
However the demand sent to the BDR91 seems 'flawed'.
If the zone, overall, is up to temperature, the valves are shut, and there's no demand to the BDR. Fine.
However, if one HR92 is then tweaked up, that valve opens (you can hear it); but no demand is sent to the BDR. So that radiator doesn't get the hot water it requires. [Unless some other zone has set a demand.]
This isn't what I'd expect, and seems like incorrect behaviour.
I would have expected that any radiator valve can set the demand (or at least influence it).
It would appear that only the representative sensor for the zone can set the demand. [?] If so, this doesn't work well for a multi-room zone.
Or I'm missing something...
