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 systems will not provide the expected comfort. Reference application bulletins CNT-APG003EN/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.

The unit’s rugged design allows installation in closet, attic or other non-condensing locations free from
obstructions or other hazards.
Remove cover by grasping at edges and gently
pulling the cover straight towards you. It should
release without much effort.

Mounting to studs: Drill 1/8” pilot holes in the four
locations marked above.
Mark four holes on the wall using the base as a
template. A level may be used to ensure accuracy.
Mounting to drywall:
If mounting to drywall with no studs behind it,
enlarge pilot holes to 3/16” for anchors (included
with the control).
Gently tap anchors into the holes.

LIVE ELECTRICAL COMPONENTS!
During installation, testing, servicing, and troubleshooting of this product, it may be necessary to work with live
electrical components. Failure to follow all electrical safety
precautions when exposed to live electrical components
could result in death or serious injury.
Wires may
enter at
any of 8
locations
Zone Panel
Wires may enter the Zone Panel through openings
on each corner and at the center of each side.
Necessary wire lengths should be considered when
determining entry points.
CAUTION: EQUIPMENT DAMAGE HAZARD - Improper
wiring can lead to equipment damage. Follow the Terminal
Connection information carefully to ensure the control is
wired properly. After wires are secure, bare wires
MUST NOT touch each other. See the Field Wiring Diagrams for specific system applications.
Route wires into “Raceways”
Run wires within the recessed wire “raceway”. Be
sure there is ample length to reach the connectors.
7
Using 1/8” blade screwdriver, attach all wires
securely to the proper terminals on the Zone
Panel. (See the Field Wiring Diagrams in the
following section.)
NOTE: The wire terminal blocks may be removed
for convenience in wiring. Ensure the terminal
block properly aligns with the pins when resetting.
Secure all wires with the supplied wire ties.

REQUIRED: A Discharge
Temperature Sensor is required.
The Discharge Temperature
Sensor (DTS) must be mounted
a minimum of 8” above the edge
of the supply duct (additional
distance is preferred when
possible). In addition, the
DTS must be 2” above the
Static Pressure Probe if used.
Locate the DTS in an area of
the discharge air duct where
less air turbulence is expected.
Avoid dead air areas where
representative discharge air
temperatures may not exist.
OPTIONAL: A return air sensor
(SEN 00462) may be installed to
monitor the return air temperature
at the indoor unit. The mixed
air sensor (SEN 00462) is used
to monitor mix air when using
bypass (future use).
Determine the proper positioning of the DTS as
follows:
• If a radiant heat source such as an electric
Drill a hole for mounting the DTS. A minimum hole
size of 7/8” will be required.
The mounting plate can be used as a template to

position the sensor so that the black thermistor
faces away from the radiant heat source. (This
will prevent a false reading due to the radiant
effect on the thermistor.)
