Balancing Tool Dialog Boxes
Use the dialog boxes described in this section to perform the main balancing tasks on individual
VAV boxes, blower coils, fan coils, unit ventilators, and water source heat pumps. To perform
balancing tasks on multiple devices, see “Facility View,” p. 16.

TU Balancing Tool Help, which is integrated in and accessible within the software
application.
