WARNING
When you handle the Carrier® ChillerVu™:
•Do not contaminate the printed circuit board with fingerprints, moisture, or any foreign material.
•Do not touch components or leads.
•Handle the board by its edges.
•Isolate from high voltage or electrostatic discharge.
•Ensure that you are properly grounded.
Screw the Carrier® ChillerVu™ into an enclosed panel using the mounting slots on the cover plate. Leave about 2
in. (5 cm) on each side of the controller for wiring. See mounting dimensions in Specifications.
If using expanders, see Installing an expander (page 12) before mounting the controller.

WARNING
Do not apply line voltage (mains voltage) to the controller's ports and terminals.
CAUTIONS
•The Carrier® ChillerVu™ 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 wire for power
1 Turn off the Carrier® ChillerVu™'s power switch to prevent it from powering up before you can verify the
correct voltage.
2 Remove primary power from the 24 Vac transformer.
3 Pull the screw terminal connector from the controller's power terminals labeled
Return
and
24 Vac/26 Vdc
.
4 Connect the transformer wires to the screw terminal connector.
5 Apply primary power to the transformer.
6 Measure the voltage at the controller's power screw terminal connector to verify that the voltage is within the
operating range of 21.6 - 26.4 Vac.
7 Insert the screw terminal connector into the controller's power terminals.
8 Turn on the Carrier® ChillerVu™'s power switch.
9 Verify that the Power LED is on and the Run LED is blinking.

NOTE
The Carrier® ChillerVu™ address is also
used to autogenerate the BACnet Device
Instance/Name for the router and the MS/TP
network number for the Open network.
See Configuring BACnet device instance and

An IP address IP network You can use one of the following:
•The
default
IP address that your system
creates:
○IP address = 192.168.168.
x
where
x
is the controller network MAC address.
○Subnet mask = 255.255.255.0

NOTES
•Carefully plan your addressing scheme to avoid duplicating addresses. If third-party devices are integrated
into the system, make sure your addresses do not conflict with their addresses.
•The controller's BACnet network and IP address can be configured using the Local Access port. See To
communicate through the Local Access port with a USB Link (page 52).
To choose an IP addressing scheme
Carefully plan your addressing scheme to avoid duplicating addresses.
By default, the Carrier® ChillerVu™ is set up for assigned IP addressing. The default IP address settings are as
follows:
•IP address = 192.168.168.x, where x = Carrier® ChillerVu™ address (rotary switch settings)
•Subnet Mask = 255.255.255.0
•Default Gateway = 192.168.168.254

•
DHCP
— If there is a DHCP server on the network, and if you have a single Carrier® ChillerVu™ or multiple
Carrier® ChillerVu™s that exist on the SAME subnet, use DHCP addressing. Skip to the section To obtain an
IP address using DHCP (page 11).
•
Custom IP addressing
— If you have multiple Carrier® ChillerVu™s that reside on different subnets, you
cannot use DHCP addressing. Instead, give each Carrier® ChillerVu™ an assigned IP address. Skip to the
section To assign a custom IP address (page 11).
NOTE
This network configuration also requires that you configure IP Broadcast Management Devices
(BBMDs). See To set up BACnet Broadcast Management Devices. (page 41)
To use a default IP address
CAUTION
The IP address must be unique on the Ethernet.
1 If wired for power, turn off the controller's power.
2 The controller only reads the rotary switch positions during power up or upon reset.
3 Set the

To wire the expander for power
CAUTIONS
•The expanders are 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.
•For the Carrier® ChillerVu™ to recognize an attached expander, you must turn on the expander before you
turn on the controller.
1 Verify that the expander's power switch is in the
Off
position.
2 Connect the 24 Vac power source to the
24 Vac/26 Vdc
and
Return
terminals, being sure to maintain proper
polarity if power is being shared.
3 Turn on the expander's power switch.
4 Verify that the expander's
Power
LED is on and the
Run
LED is blinking.
To attach expanders
Do not exceed 100 feet total wire length.
1 Wire the controller's
Xnet Remote Expansion
port to the same port on the expander.
Connect:
○Gnd to Gnd
○Xnet- to Xnet-
○Xnet+ to Xnet+
NOTE
To use more than one expander, wire their
Xnet Remote Expansion
ports together in a daisy-chain
configuration. The Carrier® ChillerVu™ must be the first device on the expander network.
2 You must set the Xnet baud rate to 500 kbps in the i-Vu® interface on the driver's
Xnet
page. See To set up
the driver.
3 If the expander network has more than one expander, place the

To set the expander's address
You must give the expanders an address that is unique on the expander network.
1 If wired for power, turn off the expander's power and the attached controller's power.
2 Set the expander's address on the rotary switch.
EXAMPLE
If the controller’s address is 2, point the arrow on the switch to 2.
NOTE
The Carrier® ChillerVu™ can have a maximum of 6 expanders. You MUST address the expanders as 1
through 6. Higher addresses will not work.
3 Turn on the expander's power and then turn on the attached controller's power. The controller reads the
powered expander's address each time you turn on the controller.
CAUTION
The first time the controller communicates with an expander, it triggers a software download. This
may occur if the expander(s) are blank (not a normal condition) and in cases where the controller’s driver has
been updated. During that time, the red
Error
LED and the green
Run
LED on the expander(s) flash in sequence.
This process may take several minutes to complete. Do not disconnect power or communications wiring during
this download.
