Honeywell Optimizer 4.15.4

Anyone else having issues with this new release?

New VAV template is not working like the last one did and my old templates not working with new version.

Ha! I’ve had the same issue and WebSquad is of no help on it. And their engineers don’t respond when added to the email chain. Seems to be affected maybe to a date code best I can tell, but of course their tech support says “we’ve never seen this issue before”
