The application software operates the rooftop unit to deliver warm supply air when in
heating mode and cold supply air when in cooling mode. The rooftop controller polls
each zone controller for its zone demand information to determine the proper mode
(heating or cooling). The zone controller then modulates the corresponding zone
dampers to provide the proper amount of conditioned air to its zone. The amount of
conditioned air is determined by the zone demand, the minimum ventilation
requirements, and the available supply air temperature. The rooftop controller
modulates a bypass damper to maintain the proper supply of static pressure, which
varies due to the opening and closing of the zone dampers.
The control system shall be available as a complete package with the required input
sensors and devices readily available. The system shall be capable of providing
complete control of HV AC functions; variable air zone control, bypass air control in

VARIABLE-AIR-VOLUME SYSTEMS' ADDITIONAL PROCEDURES
A.
Compensating for Diversity: When the total airflow of all terminal units is more than the fan
design airflow volume, place a selected number of terminal units at a maximum set-point
airflow condition until the total airflow of the terminal units equals the design airflow of the
fan. Select the reduced airflow terminal units so they are distributed evenly among the branch
ducts.

5.
Set outside-air dampers at minimum, and return- and exhaust-air dampers at a position
that simulates full-cooling load.
Select the terminal unit that is most critical to the supply-fan airflow and static pressure.
Measure static pressure. Adjust system static pressure so the entering static pressure for
the critical terminal unit is not less than the sum of the terminal unit manufacturer's
recommended minimum inlet static pressure plus the static pressure needed to
overcome terminal-unit discharge duct losses.
Measure total system airflow. Adjust to design airflow.
Set terminal units at maximum airflow and adjust controller or regulator to deliver the
designed maximum airflow. Use the terminal unit manufacturer's written instructions to
make this adjustment. When total airflow is correct, balance the air outlets downstream
from terminal units as described for constant-volume air systems.
Set terminal units at minimum airflow and adjust controller or regulator to deliver the
designed minimum airflow. Check air outlets for a proportional reduction in airflow as
described for constant-volume air systems.

If air outlets are out of balance at minimum airflow, report the condition but
leave the outlets balanced for maximum airflow.
Remeasure the return airflow to the fan while operating at maximum return airflow and
minimum outside airflow. Adjust the fan and balance the return-air ducts and inlets as
described for constant-volume air systems.
Measure static pressure at the most critical terminal unit and adjust the static-pressure
controller at the main supply-air sensing station to ensure adequate static pressure is
maintained at the most critical unit.
Record the final fan performance data.
