5.1 Label the wires:
Zoning requires a lot of wires.
• Wires to the damper motors
• Wires to the zone sensors
• Wires to the communicating system
It is recommended to label each wire after pulling
it to its location.
Crossing wires between components can
add hours of troubleshooting time to the
commissioning process.
Labeling can be done with a wire tag or use a
fine-tip permanent marker and write on the jacket
of the stat wire as shown.
IMPORTANT: Be careful to provide plenty of
room to strip the wire back without removing
the labeling.

5.3 Low Voltage Wire Connectors:
Link mode uses simple connectors for low voltage
connections. These connections are color coded
which makes the installation easier and quicker.
Wire Colors
R Red
DH White
DL Green
B Blue
Do the following to make the connections from
the actual thermostat wire to the connector.
NOTE: These connectors are necessary at the
communicating outdoor unit, communicating
indoor unit, distribution board(s), system
controller and communicating accessories.
1. Strip the Red, White, Green, and Blue
thermostat wires back 1/4”.
2. Insert the wires into the connector in the
correctly colored locations.
3. When you feel it release, allow each wire
to slide in further.
4. Pull back on the wires individually and
slightly and check if the wires are seated
properly. If each wire does not pull out for all
four wires, the connection is complete.
5. Connectors are ONE-TIME-USE ONLY. If the
thermostat wire gets broken off inside of the
connector, the connector must be replaced.
NOTE: DO NOT REUSE THE CONNECTOR
– REPLACE IT INSTEAD.
6. Wire colors are for illustration purposes only.
If using a different color, ensure it lands at
the correct terminal throughout all of the
communicating control wirings.
NOTE: For use with 18 ga. solid core thermostat wire.

5.4 Damper Wire Connectors: 5.5 Duct Dampers:
The damper connectors are push-pin connectors.
Follow the below instructions to ensure proper
attachments/removal of wires:
1. Do not push the release tabs when inserting
the wires.
2. Cut all stat wires to the same length to ensure
all wires are inserted to the same depth within
the connector.
3. Gently pull back on each wire to ensure it is
fully seated.
NOTE: It is the recommended practice to strip
the thermostat cable jacket back several inches
and insert one wire at a time into the connector
until you are sure it is seated.
4. To remove a wire, press on the release tabs
and pull the wire from the connector.
5. Do not connect more than two wires per
terminal. If more dampers are required, wire
them together externally to the zone panel.
• Each Link Zone panel can support up to three
zones.
• Power open / power closed dampers are
required.
• The damper relays can support up to four
dampers per zone.
• Be consistent with the wire coloring throughout
all damper connections.
• Each Trane/American Standard brand damper
is rated at 1.5 VA.
• 60-second travel dampers are required. See
the configuration section for details.

5.6 Wired Zone Sensors: 5.7 Component Wiring:
The right side of the zone panel is for wired
thermistors:
ZZSENSAL0400AA Wired sensors can be
incorporated in several ways:
1. Standalone temperature sensing for a zone.
2. Multiple sensors are wired in a series /
parallel circuit for averaging (see figure
below).
3. In conjunction with other sensors for
temperature averaging; using a wired sensor
alongside a wireless sensor, thermostat
or system controller. Wired temperature
sensors connected to the zone panel are
for temperature sensing only and CANNOT
sense relative humidity.
NOTE: Do not connect more than two wires per
wired temperature sensor terminal.
NOTE: Wired zone sensors can be used for
averaging. Refer to the ZZSENSAL0400A
installation guide for details.
Control wiring is easy for installations and that
only require a single transformer. The indoor
unit transformer will power and control all
components. Most components have multiple
ports to make wiring easy:
• VS Outdoor Unit = 1 connection ports
• TAMX = 2 connection ports
• S8V2-C Furnace = 3 connection ports
• System Controller = 2 ports
• Zone Panel = 2 connection ports
NOTE: The system controller ships with a 4X
distribution board to assist with point-to-point
wiring if needed. With all components being
powered from the same source, use the easiest
connection method for the installation.
NOTE: The second port on the bottom of the hub
can only be used when the hub wiring is OK to
be exposed, e.g., ush mounting of the hub and
wiring on a stud in unconditioned space.
Control wiring is more challenging if a secondary
transformer is needed. The 8X distribution board
will also be required to isolate the transformer
loads.
• The Indoor unit, outdoor unit, and air cleaner
should be powered from the indoor unit
transformer.
Do not run sensor wires
and 24 VAC wires in the
same stat wire bundle.

5.8 8X Distribution Board:
The bottom left header must be connected to
the communication circuit from the indoor unit
transformer whenever the calculated load requires
the installation of a second transformer.
This connection provides Link communication
to the distribution board and extends this
communication to all devices connected to the 8X
distribution board.
NOTE:
• The 24V Ris not connected to port 8. This
break in Reliminates the need for
transformer phasing.
• Since the two 24VAC transformers are
isolated, phasing is not a concern.
• Do not ground the secondary side of the
second transformer.
• Leave this secondary voltage oating.
The 8X distribution board provides eight
connection points for Link communication and the
24-volt power source.
The bottom of the distribution board has two
dedicated headers for the secondary transformer
and connection to the indoor unit.
Ports one through seven are to control devices
from the second transformer load.
• Furnaces will require the installation of the
50VA transformer when incorporating an
electronic air cleaner.
The Link control components (system controller,
thermostat, and zone panels) will be controlled
through the secondary transformer. The
transformer that powers the zone panels will also
power the dampers.
• This wiring technique separates the system
loads from the zoning loads; allowing
each transformer to control the dedicated
components.

5.9 Transformer Sizing: 5.10 Air Handler Transformer Sizing:
Most smaller zone systems will not require a
secondary transformer.
This table shows the transformer loads in a Link
communicating system; showing furnace and air
handler loads within one table.
Use the following tables specific to the indoor unit
type being installed components to determine if
a secondary transformer is required to power the
zoning components that will be connected to the
8X distribution board.
• Enter the quantity of each device
• Multiply the quantity as per the VA for each
device
• Add up the Total VA per operating conditions
This chart is based on worst-case conditions
• Each load is full load condition (FLA)
• All loads will never be energized at the same time

The Enable Zoning toggle is auto-enabled when Link
detects a zone panel on the communicating bus.
This toggle can be turned off if needed; such as a
new construction house where the zone sensors are
not installed yet. If the toggle is turned off without
zone sensors configured, the Link system will
control system operation as a standard non-zone
system and control system capacity from the UX360
thermostat. If this toggle is turned off before zoning
is configured and sensors are assigned; then Link
will open all dampers and control system capacity
from the smart thermostat. If this toggle is turned
off after zoning has been configured, then Link will
run the system in single-zone mode (see the zone

8.3 Renumber Zone Panels:
Renumbering zone panels is necessary when
there are two zone panels within the system.
If the zone numbers are not correctly auto-
assigned to two zone panels, initiate the
renumbering of the zone panels BEFORE
beginning zoning configuration.
The zone panel number LEDs on the two zone
panels will be swapped as a result.
Renumber Zone Panels:
Link will auto-detect the zone panels that are
wired into the communicating bus and auto-
discover zone panel numbers.
Link will auto-discover based on a first come / first
serve basis. The first zone panel that responds to
a Link communication message is Zone Panel 1.
The other zone panel will be Zone Panel 2. If
there is only one zone panel in a system, it will be
detected as Zone Panel 1.
• Zone Panel 1 controls zones 1 through 3
• Zone Panel 2 controls zones 4 through 6
Each zone panel will have a series of LEDs for
communication and zone panel numbering.
• The COMM LED will flash the number of
devices on the communication bus
• The Zone Panel 1 LED is a white LED
(bottom left image)
• The Zone Panel 2 LED is a blue LED (bottom
right image)
Zone panel 1
Zone panel 2
These LEDs are bright and can be seen at a
distance for easy viewing.
Zone renumbering has no impact on system
operation or zone names. It only swaps the zone
numbering from one panel to another.

Installation Guide
20 18-HD99D1-1A-EN
• If the arbitration of the zone panels are
reversed from the desired numbering, then
press the “Renumber Zone Panels” button
before proceeding with zoning configuration.
• Link will ask if you wish to renumber zone
panels. Confirm by pressing the blue button to
“Switch Zone Panels” or select the option for
“No Change”.
• If proceeding to switch, Link will take a few
seconds to renumber the zone panels and you
will see the LED indicators move positions as
shown below.
