Zoning controls presumed this was a zoned system as you had implied. If
this is in fact seven independent systems, it is not a zoned system
(singular). Zoning controls would be such things as motorized dampers or
valves that control zones fed be a common source furnace, boiler, etc.
At any rate, motion detecting secured thermostats and a checkup of each
system to ensure it is operating properly will go a long way towards
resolving the problem. Most times these issues are entirely operator
error where users with no knowledge of thermostats mess with them and
expect to feel instant changes in temperature, blissfully ignorant of
thermal mass, lag times, btu/hr capacity, etc. Keep those fingers off
the controls and suddenly thing start to work a lot better.

implied.
CY: I could easily have used the wrong term.
this is in fact seven independent systems, it is not a zoned
system
(singular). Zoning controls would be such things as
motorized dampers or
valves that control zones fed be a common source furnace,
boiler, etc.
CY: The building has seven separate furnaces, with seven
blowers, thermostats, etc. There are three minisplit AC in
three offices. I have not been able to find any dampers.
At any rate, motion detecting secured thermostats and a
checkup of each
system to ensure it is operating properly will go a long way
towards
resolving the problem. Most times these issues are entirely

CY: I'm not sure the church would go for motion detecting
thermostats. But, it's a good idea. Presently, only one
thermostat appears to be able to set for seven days of the
week. That's the one in the chapel. I've got that set to
come on early, and switch off, late. Wish I could set the
other six furnaces to come on early in the day and have the
building comfortable before people arrive. Sigh.

OK for gas heat, but forced hot air or hot water radiators and
convection heating or what?

Fan forced hot air. Heat registers in the ceiling. Some
return vent grilles in the floors.
