1 2FIntroduction
The Variable Air Volume (VAV) Controller is an electronic device for
digital control of single duct, dual duct, fan powered, and supply/exhaust
VAV box configurations. See 50HFigure 1. You may use the VAV as a
standalone controller or connected to the Metasysnetwork through a
Network Control Module (NCM) or Companionsystem.
When connected to the Metasys Network, the VAV provides all point and
control information to the rest of the network. The devices communicate
through an N2 Bus.
Each VAV Controller application uses a different sequence of operation,
all of which are covered in the HVAC PRO for Windows User’s Manual
(FAN 637.5).

8 VAV Controller—Variable Air Volume (VAV) Controller
When providing VAVs for projects which use Traneor TITUS
terminal boxes, consider using the AS-VAVDPTx-1 product (refer to
Building VAVDPT Applications Application Note (LIT-6363042) in the
Application Specific Controllers Technical Manual (FAN 636.3). Trane
and TITUS are both Original Equipment Manufacturers (OEMs) who
provide VAV terminal boxes for projects. Trane typically provides the
damper actuator with their terminal box, and TITUS provides the damper
actuator with their QFPC Series Fan Powered Box. The VAVDPT comes
in two models, which include a VAV Controller and a DPT-2015 Velocity
Pressure Transducer. The DPT is mounted and prewired to the cover of
the VAV. Refer to the OEM Reference Manual (FAN 638).
The VAV Controller complies with the following standards:
zFCC Part 15, Subpart J, Class A
zIEEE 472, IEEE 518
zIEEE 587 Category A
zUL 916 Listed
zVDE 0871 Class B
A factory mounted VAV box control system requires close coordination
between a variety of different disciplines. Refer to the OEM Reference
Manual (FAN 638) for factory manufacturer’s details. Although the
responsibilities may differ per city or region, the following parties are
usually involved on the job:
zcontrols contractor
zmechanical contractor
zlocal VAV box manufacturer’s representative
zbalancing contractor
zelectrical contractor
Typically, the mechanical contractor is the focal point for coordinating the
entire process. The basic responsibilities under the domain of the
mechanical contractor are:
1. Purchasing the VAV box system. Most specifications include the
OEM mounting fees and enclosures for the control system in the
mechanical contractor’s price. Mounting fees vary per box
manufacturer but ranges can be found in the OEM Reference Manual
(FAN 638).
2. Providing the release schedule for the VAV boxes to the job.
3. Contracting, or working closely with, the balancing contractor to
ensure the system is set up per the mechanical prints.
Note: The owner often directly hires the balancing contractor. This
ensures neutrality in dealing with other contractors involved in the
project.

In conjunction with the mechanical contractor, the controls contractor’s
responsibilities include:
1. Coordination of the control system release schedule to the box
manufacturer to ensure the mechanical system delivery schedule can
be met. Coordination with the local box manufacturer representative is
normally required.
2. Coordination with the electrical contractor to ensure the following
steps are covered.
z24 VAC power is provided at each VAV Controller.
zN2 Bus wiring is pulled and terminated.
zValve actuator wiring is pulled and terminated.
zZone sensor cables are pulled. The use of phone cable for
terminating zone sensor wiring allows basically anyone to
terminate zone sensors in certain locales.
zIf desired, the N2 address switches can be set by the electrical
contractor.
3. Initial loading of the HVAC PRO for Windowsconfiguration files is
done once the electrical contractor’s functions are completed in
preparation for the final system balancing.
4. Training of the balancing contractor to ensure the balancing contractor
knows how to use the Zone Terminal (ZT) or HVAC PRO for
Windows Commissioning mode so they can perform the final system
balancing.
5. Mounting and terminating the cable connections for the zone
temperature sensor. Set the N2 address switch if the electrical
contractor was not contracted to perform this function.
6. Configuring, downloading, and commissioning the controller.
