As a member of the TAC MicroNet 2000™ family of Direct Digital Controls for Variable
Air Volume (VAV) terminal boxes, the TAC MicroNet VAV Controllers offer an integral
actuator (with manual override) and an integral patented pressure transducer. There
are two models available, one with digital outputs and one without. Both models
provide programmability to accommodate a wide range of applications. Interfacing and
programming of the TAC MicroNet VAV Controller are accomplished through the TAC
MicroNet line of digital wall sensors, or the TAC MicroNet Controller Interface software.
APPLICATIONS
Designed to meet the tough control strategies of today’s VAV systems, the TAC MicroNet
VAV Controller may be applied to new or existing pressure independent terminal boxes
with or without reheat capabilities.
SYSTEMS CONNECTIVITY
Communications is optimized throughout the system to provide immediate feedback for
the facility operator. The TAC MicroNet 2000 offers the advantages of stand-alone and
networked control. The economic packaging and simple wiring allow existing pneumatic
VAV systems to be fully retrofitted with a TAC MicroNet VAV control system. The builtin actuator allows quick and effective mounting directly over the damper shaft of the
terminal box.
The digital wall sensor is durable and offers easy monitoring, including a wide variety of
interface capabilities for the user. Using the digital wall sensor, the operator can monitor
the performance of the product, edit operational values, and even reprogram the
controller, if provided the proper password level. Through the wall sensor access jack, the
TAC MicroNet Controller Interface software may be utilized to automate the balancing of
the VAV terminal box.

1000 ft (305 m) between TAC MicroNet
Integrator and most distant TAC
MicroNet Controller. 3000 ft
(914 m) total distance, including all wire
segments. Multiple U-Bus cable end
of lines are allowable and termination
resistors are not required.

TAC MicroNet Controller Interface
The TAC MicroNet Controller Interface
software is installed on a DOS-based
personal computer (PC) which allows
communication with all MN-FLOs and
MN-FLO3Ts and the TAC MicroNet
Integrator on a common U-Bus.
Permits reconfiguration, monitoring,
air balance, and editing of all TAC
MicroNet Controller configuration
data via the TAC MicroNet Controller
Interface Module (MN-CIM) which
interfaces between the RS-232 port of
a PC and the TAC MicroNet Sensor’s
communication interface jack.
TAC MicroNet VAV Air
Balance Software
The TAC MicroNet Air Balance software,
MNA-FLO-2, is installed on a DOS-based
PC and communicates to a TAC MicroNet
VAV Controller being air balanced. This
automated program steps through the
required process of air balancing. It
requests user input at the appropriate
stages, performs all calculations in the
background, and drastically iproves the
efficiency of balancing VAV terminal
boxes. The TAC MicroNet VAV Air Balance
software features:
• User friendly displays and menus.
• Operation in English and metric units
• Ability to check actuator rotation and
linkage and to automatically adjust
rotation as needed.
• Ability to adjust the flow calibration
constants, fan speed, reheat min flow,
and parallel fan setpoint.
• Detailed on-line help for using various
commands and suggesting possible fixes
for error conditions.
• Automatic logging of important balance
values such as min, max, and reheat
min flow, calibration values, parallel
fan SP, actuator rotation direction, box
number, and time/date.
• Automatically totals flow from multiple
discharges.
