ALL phases of this installation must comply with NATIONAL, STATE AND LOCAL CODES.
IMPORTANT - Proper application is critical when installing zoning systems. Not done correctly,
the HVAC and zoning system will not provide the expected comfort. Reference application
bulletins CNT-APG003-EN/Trane and CNT-APG004-EN/AS for detailed information on Zoning
Application.
IMPORTANT - This Document is customer property and is to remain with this unit. Please return to
service information pack upon completion of work.
These instructions do not cover all variations in systems or provide for every possible contingency to
be met in connection with the installation. Should further information be desired or should particular
problems arise which are not covered sufficiently for the purchaser’s purposes, the matter should be
referred to your installing dealer or local distributor.

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

NOTE: Fan power & bypass humidiers
require a separate transformer dedicated to the
humidier being installed.
NOTE: The only transformer load for the VS
outdoor unit is the SmartCharge™ solenoid. This
solenoid is only energized in the SmartCharge™
test mode. The TAMX indoor heat relays and
furnace gas valve will be disabled during the
SmartCharge™ test mode.
Evaluate the Quantity and Total VA for each
possible components in the system.
The Total System VA is based on worst-case
conditions.
The air handler ships with a 75VA transformer.
This transformer can support Total System VA
loads up to 80 VA without requiring a secondary
transformer.
