Claim 35:
36. The non-transitory computer-readable storage medium of claim 33, wherein the HVAC system has a system operating mode and zone operating modes each of which is selectable between modes including a heating mode and a cooling mode, and the method further comprises:
determining a weighted average heating mode error value and a weighted average cooling mode error value for those of the zones in respectively the heating mode and the cooling mode, based on the zone ambient temperature values and the zone temperature setpoints;
determining a switch mode error value from the weighted average heating mode error value and the weighted average cooling mode error value; and
switching or maintaining the system operating mode based on the switch mode error value and a switchover error limit.
