Handheld VAV Balancing Tool Installation Instructions 1
Applications
The Variable Air Volume (VAV) Balancing Tool allows
you to easily adjust and set the required parameters for
VAV applications that reside on the Metasys® system
VAV Modular Assembly (VMA) 1600 Series or Field
Equipment Controller (FEC) Series controllers.
The VAV balancing parameters display on the tool’s
Liquid Crystal Display (LCD). You use the dial and two
buttons on the tool to navigate through simple, intuitive
menus to balance the VAV box. The menus you see
are customized to the type of application residing in the
controller. The balancing operation also features an
adjustable time-out parameter that returns the tool and
controller to normal operation if you leave the controller
in balancing mode.
The handheld VAV Balancing Tool is lightweight and
portable. It can plug into any model of network sensor
to access the VAV controller.
The VAV Balancing Tool is compatible with the
following Metasys system BACnet® protocol devices:
• FEC loaded with a VAV application
• VMA1600 loaded with a VAV application
• Network Sensors connected to an FEC or
VMA1600 loaded with a VAV application

Wiring
Wiring Consideration and Guidelines
Observe the following guidelines when wiring the
VAV Balancing Tool:
• Do not allow the VAV Balancing Tool to hang from
the cable connection.
• Provide some slack in the cable between the VAV
Balancing Tool and the controller or network
sensor.
Power Supply, Network, and Communication
Connections
SA Bus Port
The Sensor-Actuator Bus (SA Bus) port on the
VAV Balancing Tool is a 6-pin, RS-485 port designed to
connect the VAV Balancing Tool to an accessible SA
Bus port on a Master-Slave/Token-Passing (MS/TP)
device. The MS/TP device is typically the network
sensor on the VAV controller SA Bus, using the cable
assembly provided. The SA Bus port is a straight
through, one-to-one connection (not a crossover). The
maximum allowable cable length is 100 ft.
Do not plug the SA port cable into a standard phone
jack.
Note: Connect through the MS-ZFRCBL-0 when
connecting to a wireless-enabled VMA1600.
Connecting the VAV Balancing Tool
Observe the following guidelines and procedures when
connecting the VAV Balancing Tool to your system.
1. Connect one male end of the supplied cable to the
VAV Balancing Tool.
2. Connect the other end of the cable to the controller
or network sensor.
Setup and Adjustments
The VAV Balancing Tool device itself requires no
commissioning.
Operation
Using the VAV Balancing Tool
Once the VAV Balancing Tool is physically connected
to the SA bus of the VMA or FEC controller, you can
use the tool to balance the VAV box. Refer to the VAV
Balancing Tool Technical Bulletin (LIT-12011087).
Repair Information
Do not open the VAV Balancing Tool housing. The VAV
Balancing Tool has no user-serviceable parts inside.
The VAV Balancing Tool requires no periodic field
maintenance.
