If you need more space, this
panel can be removed.
• Make all electrical connections in accordance with electrical codes and
ordinances.
• If you install the wired remote control with thermostat wire, remove 12
in. (30 cm) of the cable sheath and install only two of the conductors.
The recommended wire size is AWG 18.
• Use either the provided U-terminals or U-terminals that match the
specifications of those provided.
• Use an appropriate screwdriver for tightening the terminal screws. A
screwdriver with a small head will strip the head and make proper
tightening impossible.
• Over-tightening the terminal screws may break them.
• Tightening torque for M4 screws: 0.86–1.06 lbf·ft (12.0–14.7 kgf·cm).
Disconnect all electric power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power before servicing could result
in death or serious injury.

All field wiring MUST be performed by qualified personnel. Improperly installed
and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid
these hazards, you MUST follow requirements for field wiring installation and
grounding as described in NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.
Proper Field Wiring and Grounding Required!
WARNING
Installing/servicing this unit could result in exposure to electrical, mechanical and
chemical hazards. Before installing/servicing this unit, technicians MUST put on all
Personal Protective Equipment (PPE) recommended for the work being
undertaken. ALWAYS refer to appropriate MSDS sheets and OSHA guidelines for
proper PPE. When working with or around hazardous chemicals, ALWAYS refer to
the appropriate MSDS sheets and OSHA guidelines for information on allowable
personal exposure levels, proper respiratory protection and handling
recommendations. If there is a risk of arc or flash, technicians MUST put on all
necessary Personal Protective Equipment (PPE) in accordance with NFPA70E for
arc/flash protection PRIOR to servicing the unit. Failure to follow
recommendations could result in death or serious injury.

Important: Environmental Concerns! Scientific research has shown
that certain man-made chemicals can affect the earth's naturally occurring
stratospheric ozone layer when released to the atmosphere. In particular,
several of the identified chemicals that may affect the ozone layer are
refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those
containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all
refrigerants containing these compounds have the same potential impact
to the environment. Trane advocates the responsible handling of all
refrigerants-including industry replacements for CFCs such as HCFCs and
HFCs.
Important: Responsible Refrigerant Practices! Trane believes that
responsible refrigerant practices are important to the environment, our
customers, and the air conditioning industry. All technicians who handle
refrigerants must be certified. The Federal Clean Air Act (Section 608) sets
forth the requirements for handling, reclaiming, recovering and recycling of
certain refrigerants and the equipment that is used in these service
procedures. In addition, some states or municipalities may have additional
requirements that must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.

To configure or verify option settings on a wired remote control, use the
following procedure. Refer to Table 2 for option descriptions and
corresponding menu codes.
• If the unit does not support the function, “NONE” will be displayed.
• In configuration mode, temperature value appear in Celsius.
Configuration
Total number of units discovered
Figure 7.
Note: If a system has master and slave wired remote controls, only the
master displays the total quantity of discovered units.
• When power is applied to a newly installed wired remote control, the
device automatically begins tracking.
• To repeat tracking at any time, press the Esc and Delete buttons
simultaneously for at least 5 seconds.
• If the number of connected indoor units is increased or decreased after
installation, repeat the tracking process.
The VRF system uses the term “tracking” for the process of indoor unit
discovery and addressing. During tracking, the wired remote control
display flashes to indicate that tracking is in progress. As units are
discovered, the display shows the quantity on the left side (see Figure 7).
