UCM Control System
The IntelliPak® self-contained unit is controlled by a microelectronic control system that consists of a network of modules. These modules are referred to as unit control modules (UCM). In this manual, the acronym UCM refers to the entire control system network.
The unit size, type, heating functions, peripheral devices, options, exhaust capabilities, etc. determine the number and type of modules that a particular unit may have.
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 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.
RTM Module Board - 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 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 fan operations, and economizer operation.
Compressor Modules (SCM and MCM )
The compressor modules (single circuit and multiple circuit) energize the appro­priate compressors and condenser fans upon receiving a request for mechanical cooling. The modules monitor the compressor operation through feedback 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 zone temperature 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 settings on the TCI module for these applications should be; switches 1, 2, and 3 are “off.”
Human Interface Module (HI)
The HI module illustrated in Figure P-GI-1, on page 9, enables the user to communi­cate unit operating parameters; such as cooling and heating setpoints, demand limiting, ventilation override modes, etc.
TM
system. DIP switch
The HI module is in the unit’s main control panel. A small door located in the unit’s control panel door allows access to the HI module keypad and display window.
The HI has a 2 line by 40 character LCD screen to provide status information for various unit functions and menus to set or modify operating parameters. There is a 16-key keypad adjacent to the LCD screen to allow the user to scroll through the various menus and make adjust­ments to setpoints, etc.
The information displayed in the LCD window is top-level status information unless the operator initiates other displays.
At power-up, the human interface LCD displays one of four initial screens as illustrated in the General Status Displaysection on page 11 and de­scribed below:
1. Unit Off (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 On (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 display will go out if no keys are pressed for 30 minutes. If it goes out, simply press the STATUS key.
PKG-SVP01B-EN 7
General InformationProgramming
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)

Exhaust damper (field-installed) - closed
EXHAUST sequence “C
With the building’s exhaust fans running and the unit’s supply fan off, the condi- tioned 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

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
PURGE with duct pressure control “E
This sequence can be used when supply air control is required for smoke control.
