make the required adjustments to pulley sizes, motor sizes and electrical connections to
accommodate fan speed changes. If any adjustment have been made, repeat step 2.
• If after adjusting the fan to its maximum capacity there is still a shortage of airflow, shut off part
of the system to provide enough airflow to balance the other part of the system. This can be
done using Rover or the "Override to Unoccupied" command ("**") at the zone sensor.
3. After determining that there is enough CFM for all zones, drive all the VAV boxes to MIN.
Note: If the VAV boxes have already been assigned to groups and these groups are separate
thermal zones, then the balancing can be done on a group basis.
VAV Single Duct Unit Air Balancing
Select a group to balance and give the VAV units a recalibrate command and then the group a flow
override Drive MAX command.
Note: If the VAV boxes have not been placed in a group, each individual VAV VV550 Controller can
be overridden to Drive MAX in the Override menu in Rover. However, this will be more time
consuming.
Rover Air and Water Balancing Tool
The Rover Air and Water Balancing tool assists with air and water balancing by automating
overrides, calculations, and calibration. The Air and Water Balancing tool supports VAV VV550
Controllers and other controllers that use the LonMark Space Comfort Controller (SCC) profile.
Note: For step-by-step instructions for using this tool, refer to the Air and Water Balancing Tool
Operations guide.
You must connect your computer to a Comm5 link to communicate with the equipment on the link.
You can, however, view job information and reports offline. Refer to the Rover installation sheet for
instructions on connecting to a Comm5 link.
Important: The Air and Water Balancing tool works only with controllers that support the SCC
profile. In addition, the controllers must support the network variables for airflow.
If the Start Air Balancing button is not available on the Equipment tab, the controller
is not compatible with this tool.
