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.
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.
ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout this
literature. Read these carefully:
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTIONs
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.
NOTICE:
Indicates a situation that could result in equipment or property-damage only
accidents
WARNING
Proper Field Wiring and Grounding Required!
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.

VVZT (SZVAV), heating functions, peripheral devices, options, exhaust capabilities, etc. determine the number and type
of modules that a particular rooftop unit may employ.
The UCM receives analog or binary inputs, then processes this information and supplies outputs in the form of
modulating voltages, contact closures, etc. to control damper actuators, fan motors, compressors, valves, electric heating
coils and other electrical devices in the unit to maintain set comfort levels.
The UCM provides some equipment protection functions both directly and indirectly, such as duct pressure limits and
compressor lockouts.
Listed below are the various modules that may be employed in a UCM control system.

the return air temperature sensor, and the return air space pressure transducer to control the economizer, exhaust fan and
the exhaust dampers to maintain set space pressure.
Ventilation Control Module (7U14 IntelliPak II / 3U218 IntelliPak I)
(TRAQ dampers, DCV, outdoor air preheat) The VCM receives data from two velocity pressure sensors associated with
front and back TRAQ assemblies to measure fresh air flow entering the unit. These measurements are converted to CFM
and added to give total fresh air flow. This value can be used for monitoring purposes, to maintain flow to a minimum
fresh air flow Setpoint, or to maintain appropriate CO2 levels in the controlled space using its space CO2 sensor input and
the DCV feature. Without TRAQ assemblies installed the VCM can use DCV and the CO2 sensor input to control OA Damper
minimum position to maintain CO2 levels in the space. A preheat control relay output is also provided on this module to
maintain tempered outdoor air during ventilation using the VCM Auxiliary Temperature input. The preheat unit is usersupplied.
Multi Purpose Module (1U9 IntelliPak II / 1U105 IntelliPak I)
(return fan, energy recovery wheel, evaporative condensing) The MPM supports the function of return plenum pressure

Navigating the Human Interface Screens
In the following sections the user will be presented with a number of screens and submenus that follow the selection of
a main menu key entry (Status, Setpoints, Diagnostics, Setup, Configuration, Service Mode and Custom). When
a submenu is presented, it may be accessed by pressing the Enter key or, skipped entirely by pressing the Next key. Upon
entering a menu, or submenu, the user will navigate through the desired selections by pressing the Next and Previous
keys. The most probable keystroke would be to press Next to cycle forward through the screens as shown in these
sections, but pressing the Previous key may be desirable to review previous screens or to quickly navigate to the end
of a menu.
Once the user has navigated to a desired selection, the + (Plus) and - (Minus) keys will be pressed to cycle through the
selection range of the menu item. The range of each item selected is dependent upon the item and is listed for each screen
in the following sections. For instance, if the user has selected a Configuration item typical choices displayed with each
+ (Plus)or- (Minus) keystroke may be Installed or Not Installed.IfaSetup menu were accessed a choice may be Enabled
or Disabled. Temperature Setpoints will typically cycle through their range one degree at a time, and so on. Similar to
pressing the Previous key above, pressing the - (Minus) key to decrement through the range may provide quick access
to the desired value.
Once a change has been made to the desired menu item the user will press the Enter key to accept the change, or press
the Cancel key to ignore the modification and return the displayed item to its original value.

STATUS Menu
The status menu is used to view various operating conditions such as temperatures, pressures and humidity levels. It is
also used to view unit component status such as fan, compressor, heater, and economizer operation, as well as setpoint
status.
The screens shown in this section are for example only. Pressing the + (Plus) key while viewing any of the status display
screens will add that screen to the Custom menu. While viewing the Custom menu, a screen can be removed by pressing
the – (Minus) key.
When a status screen is displayed for 30 minutes without a key being pressed, the LCD screen will revert to the general
operating status display. If this happens, press the Status key again to return to the status menu. The following are
examples of status screens that may be viewed by pressing the Status key.
Note:
1. Many of the screens displayed in this section are applicable only for the options that are installed in the unit
and may not be visible on your unit.
2. The range for some selections depend upon a sensor connected to a control module. Normal ranges
expected will be listed for each screen shown. If the sensor is operating outside its normal limits, or has
failed, “+ERR” will appear if out of range high, and “-ERR” if it is out of range low.
