Did you try increasing the heating capacity of the central heating
coil or is is self-sizing. Are there under heated hours in the zones?
You note the warning is that the "system" may have insufficient
heating capacity. That doesn't sound like a zone problem so reheat
delta-t and zone entering max supply T likely are not the
problem. Hot Deck Max Leaving Temp. only applies to dual duct or
multi-zone systems (systems with 2 "decks"), not to single duct
systems like VAVS.
