SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment.

Introduction
Read this manual thoroughly before operating or servicing this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.
The three types of advisories are defined as follows:
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code 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.
WARNING
CAUTION
s
NOTICE
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.
Indicates a situation that could result in equipment or property-damage only.
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 refrigerantsincluding 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.
WARNING
Personal Protective Equipment (PPE)
Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:
• Before installing/servicing this unit, technicians
MUST put on all 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 PPE in accordance with NFPA 70E or other country-specific requirements for arc flash protection, PRIOR to servicing the unit.

Tracking (device discovery)
After the touchscreen is installed on the system, tracking must be executed to verify that all devices are communicating properly with the touchscreen.
To execute tracking (device discovery):
1.
Select the System Settings button on the Setting screen (
). The Installation
Settings screen appears with four buttons on it, as shown in
2. On the Installation Settings screen, select the Network & Tracking button.
3. On the Network & Tracking screen, select the Tracking button. A confirmation screen will appears. Select OK.
Note: Refer to
to see examples of the progression of screens that appear as tracking is executed from this point to completion.
4. A password request will appear: a. Touch inside the field to bring up the keypad. b. Enter the password. (The default password is 0000.)
The system will proceed to track (discover) all devices installed on the system. This process may take up to 10 minutes.
5. When you are notified that tracking is completed, select OK.
6. To save the tracking result, select Yes. Tracking results appear in a table (see the last screen in
Notes:
• If multiple touchscreen units are connected on a VRF system, you can check the box in the show/hide (S/H) column to show only the devices used by the current touchscreen, if desired.
• When executing tracking for the first time, all devices are included in one zone. To create additional zones and to manage them, see
“Setting & Editing Zones,“ p. 17

Touchscreen Guidelines
The touchscreen registers the downward pressure of a touch. Light, quick, yet deliberate presses are most effective. Touching with more pressure has no effect.
If you apply and hold pressure at more than one point, the touchscreen registers only the first touch.
For example, if you press a finger on an area of the screen that is not touch sensitive, pressing a sensitive area with another finger will not register.
Holding on to the screen with your hand can cause unintended navigation, such as from thumb or palm pressure.

• If the DI-1 ON signal is input, emergency stop status will occur: All indoor units are stopped, remote control and local user control is disabled.
• If the DI-1 OFF signal is input, the control command works normally
• DI-2 is not used.
Pattern 3: Operation/Stop, Remote control enable/disable
• If the DI-1 ON signal is input, all indoor units are stopped.
• If the DI-1 OFF signal is input, all indoor units are operating.
• If the DI-2 ON signal is input, remote control status of all indoor units is enabled.
• If the DI-2 OFF signal is input, remote control status of all indoor units is disabled.
Pattern 4: Operation/Stop
• Will operate if pulse signal is input to DI-1/2 as contact input.
– If pulse contact signal is input to DI-1, ON command will be sent to all indoor units.
– If pulse contact signal is input to DI-2, OFF command will be sent to all indoor units.
