The TruVu™ Advanced Application Controller (part no. TV-VAVB3-E2):
•Runs 2 control programs
○a VAV Product Integrated Control (PIC) program
○an optional programmable Zone Controller II program
•Supports BACnet/IP communications on the 10/100 Ethernet port as a single node in a daisy-chain
configuration or as part of a network using a ring topology
•Supports DHCP IP addressing
•Has built-in network diagnostic capture functionality for troubleshooting
•Has network statistics that can be viewed numerically or as trend graphs
•Has built-in airflow sensors
•Supports Rnet devices
•Supports Act Net devices
•Works with the i-Vu® v7.0 or later system with the latest cumulative patch
•Provides 4 universal inputs, 3 binary outputs, and 2 analog outputs
The TV-VAVB3-E2 controls zone temperature using single duct or fan-powered terminals in a Variable Air Volume
application. The controller regulates the flow of conditioned air into the space. Buildings with diverse loading
conditions can be supported by controlling the local terminal's supplemental heat. The TV-VAVB3-E2 provides
dedicated control functions for single duct and fan-powered terminals with modulating heat, staged ducted heat
(up to 3 stages of ducted heat for single duct or up to 2 stages of ducted heat for fan-powered terminals), or
combination baseboard and ducted heat.
Although a TV-VAVB3-E2 can be included in a VVT system, this documentation focuses mainly on using it in VAV
applications.
NOTE This document gives instructions for field-installation of a TV-VAVB3-E2 in an i-Vu® system. However, TV-
VAVB3-E2s are available factory-mounted to Carrier’s 35 single duct and 45 parallel and series fan terminals. All
terminals require an integrated duct temperature sensor.

Linkage
The i-Vu® Control System uses linkage to exchange data between the zone terminals and their air source to form
a coordinated HVAC system. The system's air source controller and zone controllers are linked so that their data
exchange can be managed by one zone controller configured as the VAV Master.
A VAV Master can have a maximum of 63 slave zone controllers reporting to it. A typical VAV Master has slave
controllers that are sequentially addressed beneath its own address on the same network. A VAV Master may also
have zones reporting to it that are not sequentially addressed, including those on other networks. These are
commonly referred to as Rogue zones.
A linked VAV system can be as simple as a single network with a VAV Master and slaves, or it can be as complex
as multiple networks with VAV sub-masters and slaves on other networks. See the following examples.
EXAMPLE #1:A simple network. The VAV Master exchanges data between the slave controllers and the AHU
controller. The linked controllers on the network must be sequentially addressed, and the VAV Master must have
the highest address.
EXAMPLE #2: The above network plus one slave controller (11) not sequentially addressed and one slave
controller on a different network.

EXAMPLE #3: The above network plus sub-masters and their slaves. (For VAV systems only. VVT systems do not
support sub-masters.) The sub-masters exchange data between their slaves and the VAV Master, and the VAV
Master handles data exchange for the whole system including the Air Source.
You set up linkage for the system by defining the Linkage properties for each controller.
Safety Considerations
CAUTION
Air conditioning equipment will provide safe and reliable service when operated within design specifications. The
equipment should be operated and serviced only by authorized personnel who have a thorough knowledge of
system operation, safety devices, and emergency procedures.
Good judgment should be used in applying any manufacturer's instructions to avoid injury to personnel or damage
to equipment and property.
WARNING Electrical Shock Hazard
Failure to follow this warning could cause personal injury, death, and/or equipment damage.
Disconnect all power to the unit before performing maintenance or service. Unit may automatically start if power is
not disconnected.
WARNING Follow all local, state, and federal laws regarding disposal of equipment containing hazardous
materials such as mercury contactors.

Zone sensors
You can wire ZS sensors and/or a Wireless Adapter that communicates with wireless sensors to the TV-VAVB3-
E2's Rnet port. You can have up to 10 ZS and/or wireless sensors.
NOTES
•A control program can use no more than 5 ZS sensors, so you must use multiple control programs if your
Rnet network has more than 5 sensors.
•ZS and wireless sensors can share the Rnet with an Equipment Touch or TruVu™ ET Display.
CAUTION Rnet power
The Rnet port provides 12 Vdc at up to 260 mA. When determining which devices to put on the Rnet, verify that
the total current draw of the sensors does not exceed the controller's Rnet power. See the sensor's Installation
and Start-up Guide to determine the power required.
Touchscreen devices
You can connect the TV-VAVB3-E2 to the touchscreen devices using the Rnet port or one of the Comm/Service
ports.
Rnet port
You can wire an Equipment Touch or TruVu™ ET Display to the TV-VAVB3-E2's Rnet port to view or change the
controller's property values, schedule equipment, view trends and alarms, and more, without having to access the
system's server. The Rnet port can have one Equipment Touch or TruVu™ ET Display, plus ZS sensors and/or a
Wireless Adapter that communicates with wireless sensors.
NOTE These touchscreen devices are not powered by the Rnet port.
•The TruVu™ ET Display requires a 24 Vdc external power source.
•The Equipment Touch requires a 24 Vac external power source.
USB ports
You can connect the TruVu™ ET Display to either of the TV-VAVB3-E2's Comm/Service ports to view or change the
controller's property values, schedule equipment, view trends and alarms, and more, without having to access the
system's server.
NOTES
•These touchscreen devices are not powered by the USB port.
•The TruVu™ ET Display requires a 24 Vdc external power source.
CAUTION A touchscreen device can share a power supply with the Carrier controller if:
•The power source shared by the controller and Equipment Touch is AC power.
•The power source shared by the controller and TruVu™ ET Display is DC power.
•You maintain the same polarity.
•You use the power source only for Carrier controllers.

To mount the TV-VAVB3-E2
1 Turn the damper shaft to fully close the damper position. Ensure the damper is closed.
2 Mount the controller to the VAV terminal by sliding the clamp assembly onto the damper shaft.
3 Mount and secure an enclosure to cover the TV-VAVB3-E2.
NOTE For service access, we recommend that you allow at least 1 foot (.3 m) of clearance between the front
of the enclosure and adjacent surfaces.

4 Secure the controller and the actuator by screwing the rear mounting tab into the VAV box, using the screw
that is supplied with the TV-VAVB3-E2.
NOTE We recommend that you use the M5 - .75 in. (19 mm), self-tapping screw that is shipped with the TV-
VAVB3-E2.
CAUTION Center the washer in the mounting screw slot. Secure the TV-VAVB3-E2 to allow lateral
movement of the damper shaft.
5 Hold down the TV-VAVB3-E2’s actuator release button and rotate the actuator clamp in the same direction
that closed the damper. Rotate the clamp until it stops, then rotate it back one notch.
6 Release the button.
7 Tighten the actuator clamp to the damper shaft by tightening the two M5 nuts.
8 Hold down the actuator release button and rotate the damper from fully closed to fully open. If the damper
traveled less than 90 degrees, do the following to prevent the damper traveling past fully open:
a) Loosen the appropriate stop clamp screw.
b) Move the stop clamp until it contacts the
edge of the actuator cam.
c) Tighten the screw.
9 Hold down the actuator release button, rotate the damper to verify that it opens and closes, then release the
button.

CAUTIONS
•The TV-VAVB3-E2 is powered by a Class 2 power source. Take appropriate isolation measures when mounting
it in a control panel where non-Class 2 circuits are present.
•Carrier controllers can share a power supply as long as you:
•Maintain the same polarity.
•Use the power supply only for Carrier controllers.
To remove the TV-VAVB3-E2's cover
