Features and
Benefits
Figure 8. Track er System Architecture
Static Pressure Sensor
The static pressure sensor measures
duct static pressure and positions the
bypass damper(s) to maintain the static
pressure setpoint.

Quick Connect
Minimizes field wiring labor and
assures wiring consistency
Duct Temperature Sensor
The supply air temperature sensor
allows the CCP to control heating and
cooling stages to maintain the supply
air temperature. Supply air
temperature setpoints can be edited
through the operator display or
PC software.
Tracker System Integration
The VariTrac system can be fully
integrated with the new family of
Tracker building controls. A Tracker
building management system can
manage multiple VariTrac systems from
a single control point.
Tracker System Summary
• Controls up to 10 VariTrac systems
from a single Tracker panel for easy
building operation
• LCD touch-screen operator display or
Tracker PC software interface provides
single-point building management by a
local operator
• 365-day scheduling function and the
flexibility of up to 10 schedules
• Assign all systems to a single
schedule, if desired, for simplified
schedule changes
• Exception scheduling feature for easy
management of vacations and holidays
• Automatically adjusts for daylight
savings time and leap year
• Remote communications capability
via modem for system programming
and control

Communicating Bypass
Controller
The communicating bypass controller
is a single control enclosure with the
following integrated devices included:
• integrated UCM board
• static pressure sensor
• discharge air temperature sensor
The communicating bypass controller
directly controls the bypass damper
and communicates duct conditions to
the central control panel via a simple
twisted shielded wire pair.
