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.

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)

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.
