FEATURES
Designed for new or existing systems, the VAV series
controller may be applied to pressure independent
terminal boxes with, or without, reheat capabilities.
The VAV controller offers the following types of Box
Configuration and Reheat control strategies:
• Cooling.
• Series Fan.
• Parallel Fan.
• Induction.
• Staged Electric Reheat.
• Floating/Proportional Hydronic Reheat.
• Time Proportioned.
• Capability to function in standalone mode or
as part of a LonWorks TP/FT-10 Free Topology
communications network.
• Proportional (P), Proportional Plus Integral (PI),
and Proportional Plus Integral and Derivative (PID)
control for cooling and heating.
• Patented pressure transducer for years of reliable,
accurate air flow readings.
• Air balancing using the TAC I/A Series
MicroNet VAV Flow Balance software.
• Directly compatible with terminal boxes which
contain a synchronous-motor-driven damper
actuator.
• Conforms to the LonMark VAV controller profile.
• Plenum-rated enclosure allows direct mounting in
plenum.
TAC I/A Series VAV FLow Balance Software
Provides flow balancing for networked and
standalone VAV series controllers. Features include:
• Local network control.
• Damper and fan adjustment.
• Setpoint monitoring and adjustment.
• Flow validation and calibration.
• Sequence, calibration, and control setpoint logs.
COMMUNICATIONS
Lon Works Networks
L
onWorks communications network uses an
FTT-10 Free Topology configuration. Controllers on
a L
onWorks network can communicate with each
other in a peer-to-peer fashion. A L
has a communications speed of 78k baud, using
unshielded, twisted-pair cabling, with connections
that are not polarity sensitive.
S-Link
The Sensor Link (S-Link) communications wiring
provides power and a communication interface for an
MN-Sx TAC I/A Series MicroNet sensor. The various
MN-Sx sensors can provide room temperature,
room humidity, setpoint adjustment, and occupancy
override. This connection uses two-wire, unshielded
cable and is not polarity sensitive. Maximum wire
length allowed between a controller and a TAC I/A
Series MicroNet Sensor is 200 ft (61 m).
onWorks network
Software Capabilities
• Conforms to the LonMark guidelines.
• WorkPlace Tech Tool is capable of reconfiguring
and editing application configuration data to
fit a wide range of variable air volume control
requirements.
• HVAC interoperability achieved through use of
LonMark HVAC profiles.
• Air balancing provided by the I/A Series MicroNet
VAV Flow Balance software.
