Classification: CPC F  G | IPC F

Claim 0:
1. A heating, ventilation, and air conditioning (HVAC) system comprising:
HVAC equipment configured to provide conditioned air to a conditioned space that is divided into zones; and
control circuitry operably coupled to the HVAC equipment and configured to at least:
receive zone priority levels and zone temperature setpoints, at least one of the zones having a higher priority level than others of the zones;
receive an indication of zone ambient temperature values;
determine requested zone capacity values to maintain the zone ambient temperature values within a threshold deviation of respective ones of the zone temperature setpoints;
determine target zone capacity values from the requested zone capacity values and zone size values, and from the zone priority levels responsive to a total of the requested zone capacity values that is less than a minimum capacity of the HVAC system or greater than a maximum capacity of the HVAC system, wherein
the control circuitry determines the target zone capacity values corresponding to the requested zone capacity values scaled by respective ones of the zone size values, responsive to the total of the requested zone capacity values between the minimum capacity and the maximum capacity;

cause the HVAC system to provide the conditioned air to the zones according to respective ones of the target zone capacity values, wherein
the HVAC equipment is set up in an installation with zone dampers controllable to regulate airflow of the conditioned air to respective ones of the zones;

convert the target zone capacity values to target zone airflow values for the zones of the conditioned space;
determine a damper position set from the target zone airflow values; and
actuate the zone dampers to respective damper positions of the damper position set.
