UCM Control System
The IntelliPak™self-contained units are controlled by a
microelectronic control system that consists of a network
of modules and are referred to as Unit Control Modules
(UCM).
The unit size, type, heating functions, peripheral devices,
options, exhaust capabilities, etc. determine the number
and type of modules that a particular rooftop unit may
employ.
These modules perform specific unit functions using
proportional/integral control algorithms. They are
mounted in the unit control panel and are factory wired to
their respective internal components.
By processing analog and binary inputs, each module
supplies outputs in the form of modulating voltages (from
PKG-SVP01D-EN 5
General Information
other unit modules, sensors, remote panels, and customer
binary contacts) to perform the applicable request; such as
economizing, mechanical cooling, heating, ventilation.
The UCM provides some equipment protection functions
both directly and indirectly, such as duct pressure limits
and compressor lockouts. Following is a description of
each module’s function within the UCM system.
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.
Rooftop Module Board (RTM)- Standard on all
units
The RTM is the central processor of the system. It
continuously receives information from the other unit
modules, sensors, the remote control panel, and customer
supplied relays. It then interprets this information and
responds to cooling, heating, and ventilation requests by
directing the other modules in the system to energize the
proper unit components. It also directly initiates supply
and exhaust fan operations, and economizer operation.
Compressor Module (SCM/MCM)
The Compressor module, (Single Circuit & Multiple
Circuit), upon receiving a request for mechanical cooling,
energizes the appropriate compressors and condenser
fans. It monitors the compressor operation through
feedback information it receives from various protection
devices.
Heat Module (Standard on all heating units)
The Heat module directs the unit’s heater to stage up and
down to bring the temperature in the controlled space to
within the applicable heating SETPOINT.
Exhaust/Comparative Enthalpy Module
(ECEM)(Option)
The ECEM is on units with the comparative enthalpy
option. It receives data from the return air humidity sensor,
the return air temperature sensor, and the return air space
pressure transducer and controls dampers to maintain
space pressure and humidity levels.
Generic Building Automation System (GBAS)
Module Option
The GBAS module links the RTM with non-Trane building
control systems to enable communication (input/output
interface) between the systems. It can accept external
setpoints for cooling, heating, demand limiting, and S/A
pressure.
Ventilation Override Module (VOM) Option
The VOM can control the unit’s air handling functions to
perform customerspecified functions, such as space
pressurization, exhaust, purge, unit off, etc.
Interprocessor Communications Board (IPCB)
Option
The IPCB is used to expand communication from the unit’s
UCM network to a remote human interface panel. DIP
switch settings on the IPCB module for this application
should be; switches 1 and 2 “off,” switch 3 “on.”
Trane Communications Interface Module (TCI)
Option
The TCI module allows external setpoints for most of the
unit functions to be communicated to the unit’s UCM
network via a Trane ICS™ system. DIP switch settings on
the TCI module for these applications should be; switches
1, 2, and 3 are “off.”
BACnet Communication Interface Module
(BCI) (Optional - used on units with Trane ICS
or 3rd party Building Automation Systems)
The BACnet Communication Interface module expands
communications from the unit UCM network to a Trane
Tracer Summit, or a 3rd party building automation system
that utilizes BACnet, and allows external SETPOINT and
configuration adjustment and monitoring of status and
diagnostics.
Lontalk Communication Interface Module
(LCI) (Optional - used on units with Trane ICS
or 3rd party Building Automation Systems)
The LonTalk Communication Interface module expands
communications from the unit UCM network to a Trane
Tracer Summit, or a 3rd party building automation system
that utilizes LonTalk, and allows external SETPOINT and
configuration adjustment and monitoring of status and
diagnostics.
Human Interface Module
The Human Interface (HI) Module illustrated in Figure 1 is
the device which enables the customer, building owner, or
contractor, to communicate to the Rooftop unit the
necessary parameters for unit operation such as cooling
and heating SETPOINTs, demand limiting, ventilation
override modes, etc.
The HI Module is located in the unit’s main control panel.
A small door located in the unit’s control panel door allows
access to the HI Module’s keypad and display window.
There is a 2 line by 40 character LCD screen which provides
status information for the various unit functions as well as
menus used to set or modify the operating parameters.
There is a 16 key keypad adjacent to the LCD screen, which
allows the operator to scroll through the various menus
and make adjustments to the SETPOINTs, etc.
The information displayed in the LCD window will be toplevel status information unless the operator initiates other
displays.
6 PKG-SVP01D-EN
General Information
At power-up, the Human Interface LCD will display one of
four initial screens illustrated in the “General Status”
section.
1. Unit Status (Unit Off or Stopped) (The unit is
configured and operational, but is not running). This
screen shows state, mode, and function information
when the unit is off or stopped.
2. Unit Status (Unit On) (The unit is configured and
operational, and is running). This screen shows state,
mode, and function information when the unit is on.
3. VOM Active (a ventilation override command was
received) This screen shows that the unit is in a
Ventilation Override Mode.
4. No Configuration (the unit needs to be configured).
This screen shows that required configuration data is
missing.
The LCD screen has a backlight that makes the information
easier to read. The light will go out if no keys are pressed
for 30 minutes. If it goes out, simply press the STATUS key.
Ventilation Override Module (VOM) Definitions
The ventilation override module can be field-configured
with up to five different override sequences for ventilation
override control purpose. When any one of the module’s
five binary inputs are activated, it will initiate specified
functions such as; space pressurization, exhaust, purge,
purge with duct pressure control, and unit off.
Once the ventilation sequences are configured, they can
be changed unless they are locked using the HI. Once
locked, the ventilation sequences cannot be unlocked.
The compressors and condenser fans disable during the
ventilation operation. If more than one ventilation
sequence activates, the one with the highest priority (VOM
“A”) begins first, with VOM “E” having lowest priority and
beginning last.
A description of the VOM binary inputs follows below.
UNIT OFF sequence “A”
When complete system shut down is required, the
following sequence can be used.
• Supply fan – Off
• Supply fan VFD – Off (0 Hz) (if equipped)
• Inlet guide vanes – closed (if equipped)
• Outside air dampers – Closed
• Heat – all stages – Off, Modulating heat output at 0 vdc
• Occupied/Unoccupied output – Deenergized
• VO relay – Energized
• Exhaust fan (field-installed) - Off
• Exhaust damper (field-installed) - Closed
PRESSURIZE sequence “B”
This override sequence can be used if a positively
pressured space is desired instead of a negatively

• Occupied/ unoccupied output - energized
• VO relay - energized
• Exhaust fan (field-installed) - off
• Exhaust damper (field-installed) - closed
EXHAUST sequence “C”
With the building’s exhaust fans running and the unit’s
supply fan off, the conditioned space becomes negatively
pressurized. This is desirable for clearing the area of
smoke when necessary; i.e. from an extinguished fire, to
keep smoke out of areas that were not damaged.
• Supply fan – off
• Supply fan VFD – off (0 Hz) (if equipped)
• Inlet guide vanes – closed (if equipped)
• Outside air dampers – closed
• Heat – all stages – Off, hydronic heat output at 0 vdc
• Occupied/Unoccupied output – deenergized
• VO relay – energized
• Exhaust fan (field-installed) - on
• Exhaust damper (field-installed) - open
PURGE sequence “D”
This sequence could be used for purging the air out of a
building before coming out of unoccupied mode of
operation on VAV units. Also, it can be used to purge
smoke or stale air.
• Supply fan – on
• Supply fan VFD – on (60 Hz) (if equipped)
• Inlet guide vanes/VAV boxes – Open (if equipped)
• Outside air damper – Open
• Heat – all stages – Off, Modulating heat output at 0 vdc
• Occupied/Unoccupied output – Energized
• VO relay – Energized
• Exhaust fan (field-installed) - On
• Exhaust damper (field-installed) - Open
PKG-SVP01D-EN 7

This sequence can be used when supply air control is
required for smoke control.
• Supply fan – on
• Supply fan VFD – on (if equipped)
• Inlet guide vanes – controlled by supply air pressure
control function with supply air pressure high limit
disabled
• Outside air dampers – open
• Heat – all stages – off, hydronic heat output at 0 vdc
• Occupied/unoccupied output – energized
• VO relay – energized
• Exhaust fan (field-installed) - on
• Exhaust damper (field-installed) - open
Note: Each system (cooling, exhaust, supply air, etc.)
within the unit can be redefined in the field for each
of the five sequences, if required. Also the
definitions of any or all of the five sequences may
be locked into the software by using the human
interface panel keypad. Once locked into the
software, the sequences cannot be changed.
Programming the Unit
The UCM must be programmed with “job-specific”setup
information for the unit to operate and function properly.
The data necessary for unit operation will vary depending
on factors such as unit size, type, and options.
This manual provides step by step instructions for
programming setup information using the HI or RHI. It also
includes instructions for checking unit operating status,
accessing and clearing diagnostics, and performing
service tests. Some of the displays in this manual may not
appear on the HI or RHI screen during programming. Only
applicable screens for specific unit options and operating
parameters will display.
Any steps that do not apply to all unit types are marked
accordingly. Ignore any steps that do not apply to your unit
and/or application. Continue this process until all
applicable screens are programmed with the required
information.
