The TruVu™ Advanced Application Controller (part no. TV-VVTZC-E2):
•Runs 2 control programs
○a VVT zone Product Integrated Control (PIC)
○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
•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-VVTZC-E2 controls zone temperature in single duct, fan powered, Variable Volume and Temperature (VVT®)
applications. It has a built-in actuator, uses a patented flow control algorithm, and mounts directly on the VVT
terminal damper shaft.
The TV-VVTZC-E2 with actuator maintains zone temperature by operating the terminal fan and regulating the flow
of conditioned air into the space. Buildings with diverse loading conditions can be supported by controlling the air
source heating and cooling sources or supplemental heat. The TV-VVTZC-E2 provides dedicated control functions
for single duct and fan-powered terminals with modulating heat, staged duct 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.
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, zone controllers, and bypass controller are linked so
that their data exchange can be managed by one zone controller configured as the VVT Master.
You can disconnect the actuator from the controller and mount them separately, connecting them with just the
actuator cable or using an additional extension cable, up to a maximum distance of 300 feet.

Zone sensors
You can wire ZS sensors and/or a Wireless Adapter that communicates with wireless sensors to the TV-VVTZC-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-VVTZC-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-VVTZC-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-VVTZC-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-VVTZC-E2
1 Turn the damper shaft to fully close the damper position. Ensure the damper is closed.
2 Mount the controller to the VVT terminal by sliding the clamp assembly onto the damper shaft.
3 Mount and secure an enclosure to cover the TV-VVTZC-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 VVT terminal, using the
screw that is supplied with the TV-VVTZC-E2.
NOTE We recommend that you use the M5 - .75 in. (19 mm), self-tapping screw that is shipped with the TV-
VVTZC-E2.
CAUTION Center the washer in the mounting screw slot. Secure the TV-VVTZC-E2 to allow lateral
movement of the damper shaft.
5 Hold down the TV-VVTZC-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.

WARNING Do not apply line voltage (mains voltage) to the controller's ports and terminals.
CAUTIONS
•The TV-VVTZC-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-VVTZC-E2's cover
TIP To attach the cover to the base, secure a cable tie through the two cable tie brackets as shown below.

To wire for power
1 Remove power from the power supply.
2 Remove the TV-VVTZC-E2's cover.
3 Pull the red screw terminal connector from the controller's power terminals labeled 24V.
4 Connect the power supply's wires to the red screw terminal connector.
5 Connect an 18 AWG or larger wire from the power supply's negative (-) terminal to earth ground. This wire
must not exceed 12 in. (30.5 cm).
6 Apply power to the power supply.
7 Measure the voltage at the red screw terminal connector to verify that the voltage is within the operating
range of 20.4 to 28.8 Vac or 21.6 to 28.8 Vdc.
8 To verify the polarity of the wiring, measure the voltage from the negative terminal of the red screw terminal
connector to a nearby ground. The reading should be 0V.
9 Insert the red screw terminal connector into the controller's power terminals.
10 Verify that the LED on top of the controller is on.
