The three types of advisories are defined as follows:

WARNING

Proper FieldWiring 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

CAUTIONs

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 situationthat could resultin equipment or property-damage only accidents.

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 handlingof all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Important Responsible Refrig er ant 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!

Installing/servicing this unit could result in exposure to electrical, mechanical and chemical hazards.

• Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE and arc flash clothing).

ALWAYS refer to appropriate Material Safety Data

Sheets (MSDS)/Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.

• When working with or around hazardous chemicals,

ALWAYS refer to the appropriate MSDS/SDS and

OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.

• If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE

TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL

METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.

General Information

Overview of Manual

Note: One copy of the document is shipped with VAV

units that have UCM 4.2 DDC controllers and is customer property. It must be retained by the unit's maintenance personnel.

This booklet describes proper installation, operation, and

maintenance procedures for delivered air systems. By carefully reviewing the information within this manual and following the instructions, the risk of improper operation and/or component damage will be minimized. Should equipment failure occur, contact a qualified service organization with qualified, experienced HVAC technicians to properly diagnose and repair this equipment.

Chapter Overview

This chapter contains information about the following:

• Unit Control Module 4.2 (UCM 4.2)

• Specifications

• UCM 4.2 Enhancements

• UCM 4.2 Features

• Shipping

• Storage

Unit Control Module 4.2 (UCM

4.2)

The UCM 4.2 is a microprocessor-based, Direct Digital

Controller (DDC) for the (Variable Air Volume) VAV terminal unit. It contains the control logic to modulate the flow of supply air through theVAV terminal in response to the load requirements within the VAV zone.

The function of theUCM is tocontrol theVAV terminal unit

to vary the volumetric airflow rate to the zone. Units have been made with either pneumatic, analog electronic, or microprocessor controls (DDC VAV).This manual discusses only terminal units with Comm4 DDC/VAV controls. Factory installed DDC/VAV controls are available with all single duct terminal units, dual duct units, as well as parallel fan-powered and series fan-powered units.Two UCMs are required for dual duct units (one for the heating duct and one for the cooling duct).

The UCM modulates a VAV's damper blade based on a

zone temperature, measured airflow, and airflow set points to continuously control conditioned air delivery to the space.The volume of incoming air is monitored and the damper adjusts to provide accurate control independent of the duct pressure.The damper modulates between operator airflow set points depending on space conditions. Additionally, fan and heat outputs may be energized depending on the application. Available inputs

include a twisted/shielded communication link, zone sensor, auxiliary temperature sensor (optional), CO Sensor (optional), and Occupy/Unoccupy Sensor (optional), and 24 VAC power.

Specifications

Power Requirements

The UCM 4.2 requires 24VAC,50/60 Hz NEC Class2 power. The UCM itself consumes 8 VA. Our factory installed

devices draw from 3 to 12 VA.Typical values are 4 VA for a damper actuator, 10 to 12 VA for an electric heat contractor, and 6 VA for a fan relay.The NEC Class 2 transformer should be sized to handle the total VA of all devices.The binary outputs are rated at steady-state 12VA max.

Operating Environments - UCM 4.2

32° to 140°F (0° to 60°C), 10% to 90% relative humidity, noncondensing

Storage Environments - UCM 4.2

-40° to 150°F (-40° to 65.6°C), 10% to 90%relative humidity, non-condensing

Mounting

Typically, the UCM 4.2 is factory installed. However, UCM

4.2 is available with retrofit kits, in which case it must be field installed.

Tracer Summit and UCM 4.2 Communications

Link Wiring

Communications Link wiring must be 18 AWG twisted shielded pair wire. Each conductor must be stranded tinned copper.The maximum totalwire length is 5,000 feet (1,524 m). See “UCM 4.2 Installation andWiring,” p. 11 for further information about wire selection.

UCM 4.2 Enhancements

• The enhanced VAV UCM is backward compatible with VariTrane® DVAV boxes (VXXD and VXXE) VariTrac®

dampers, and VariTrac II dampers.

• UCM 4.2 adds support for operation with VariTrane

Series F valves (¼-turn blade dampers) via 90-second drive time.

• UCM 4.2 adds a second, C02interfacing, mode of

operation to the auxiliary analog input (TB3-5).This is a 1 to 10 volt DC input with a mapping of input voltage to C0

output data value of 200 parts per million (PPM)

of C0

per volt.The use of this new auxiliary analog

input as an interface to a C0 exclusive with the use of the input as auxiliary temperature input.Therefore, the use of the C0 interfacing mode of operation is not recommended for stand-alone applications requiring auto-changeover.

detector is mutually

6 VAV-SVX01D-EN

General Information

• UCM 4.2 adds a binary 24 VAC, dry contact input. It can be configured either as a generic input or as an occupancy detector input.

• UCM 4.2 adds a VariTrac Bypass Damper mode of operation. In this mode, supply air temperature and supply air pressure is made available on the Comm4 link.The damper position is a Comm4-control parameter. A Comm4 configurable failsafe position was added.The supply air temperature uses a new "S" input (TB3-7).The use of this new input is mutually exclusive with the zone temp input (TB3-1).

• UCM 4.2 now assumes the hot water valve is closed after reset.This prevents a reset during hot water override from causing the valve to stop moving.This also changes the behavior after reset, when there is a reheat demand, the hot water valve now opens (from assumed closed position) to the desired reheat position.

• In a wireless system, the hard-wiredsensor can now be configured as not present.The hard-wired sensor failures will not be reported as long as at least one wireless zone sensor is reporting valid temperature values.

Note: This is an older wireless system that has been

obsoleted and not the onediscussed in the wireless zone sensor section.

• For standalone units, series or parallel fan operation will use the unoccupied fan control when the local unoccupied request (** function) is received. In UCM

3.3 and prior, the fan would operate as if occupied during local unoccupied request.

• UCM 4.2 adds a local minimum heating flow set point.

The use of and value of this set point is configurable.

UCM 4.2 Backward Compatibility

UCM 4.2 can be used to replace UCM I, UCM II, and UCM III with no compatibility issues. However, if the communicating device (i.e. Command Unit I or Comfort Manager™ I) is a COM 3 device (1992 or earlier), then you will need an upgrade chip.The Comfort Manager chip upgrade is Kit 1511 and the Command Unit chip upgrade is Kit 1512.

UCM 4.2 Features

UCM Outputs

UCMTriac outputs for controlling a fan or reheat are rated at 12 VA each.

Wiring Diagram

Figure 3, p. 14 shows a typical wiring diagram for the

redesigned UCM hardware.The new service part number is BRD04939.

Thumbwheel Set Point Calibration

If there is adiscrepancy between a measured temperature and what theUCM reports, a calibrationoffsetvalue can be edited in the UCM setup screen to correct the displayed value.

Flow Sensor Calibration

If there is a discrepancy between a measured flow and what the UCMreports,the measured valuecan be entered, which automatically calculates a calibration multiplier to correct the displayed value.

Water Valve Override

Each UCM that has proportional or staged hot water heat outputs can be edited to override the water valve to its maximum position.

Ventilation Set Points and Ratio Calculation

Set point values needed for a space to satisfy indoor air quality requirements are provided. A resultant ventilation ratio can be used to calculate an air handler's outside air damper minimum position or other control strategies.

VAV-SVX01D-EN 7

General Information

Water Heat Output Configuration

UCMs that have hot water heat outputs can be configured for normally open or normally closed.

Zone Sensor Functions

Zone sensor functions now include: air valve drive to maximum, use unoccupied set points, timed override, and cancel timed override.

Slaving of Zone Sensors

Up to three(3) UCM 4.2 may be connected to a single zone sensor.

Generic UCM Capability

UCM 4.2 can be configured to control non-Trane VAV boxes.

Shipping

EachVAV product and its service literature are shipped in the same package. When unpacking, make sure that the literature is notlost or discardedwith the packing material.

Visually inspect the individual components for obvious

defects or damage. All components are thoroughly inspected before leaving the factory. Any claims for damage incurred during shipment must be filed with the carrier.

Storage

When any component of the VAV system and/or field

installed accessories must be stored for a period of time prior to being installed, they must be protected from the elements.The storage location temperature should be between -40° to 150°F (-40° to 65.6°C) and the relative humidity should be 10% to 90%, non-condensing.

The warranty will not cover damage to theVAV system or

controls due to negligence during storage. A controlled indoor environment must be used for storage.

VAV Start Up/Check Out Procedure

Chapter Overview

This chapter contains information about the following:

• Unit 4.2 Pre-Power Check-Out

• Light Emitting Diode (LED) Operations

• Zone Sensor Check-Out

UCM 4.2 Pre-Power Check-Out

WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.

• Check the supply voltage atTB1. Proper polarity must be maintained.TB1-1 is the hot side (+) andTB1-2 is the ground side (-) of the 24 VAC input.The UCM cannot be powered from a common 24 VAC transformer that is supplying power to a device containing a full-wave rectifier bridge in its power supply.The acceptable voltage is 20 to 28 VAC (24 VAC cataloged). However, voltages at either extreme may result in increased system instability.

• Verify that communications wiring has properly been terminated atTB2-1 (+) andTB2-2 (-). Polarity is very important on the communications link.

• Verify that the zone sensor connections are correct as detailed in the UCM wiring chapter.

• Verify that the proper unit DIP switch settings have been set on each UCM.

• Verify that the tubing is properly connected to the transducer.

Power Requirements

NOTICE:

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of conductors. Failure to use copper conductors could result in equipment damage.

Use at least 16 AWG for power wiring and connect to terminalTB1-1 (+) andTB1-2 (-). 24 VAC is required to power the UCM control and has an acceptable voltage tolerance of 20 to 28 VAC. Replace the UCM control box cover after field wiring to prevent any electromagnetic interference.

Note: A dedicated 24 VAC, 50VA NEC class 2 transformer

is recommended to power the UCM. When powering multiple UCM’s from one transformer, polarity must be maintained.TerminalTB1-1 is designated positive (+) and terminalTB1-2 is negative (-) to the unit casing ground.

The power consumption for cooling only Series F Models

(VariTrac andVariTrane) is 12 VA (4 VA for the air valve/ actuator and 8 VA for the board).To determine the total

VAV-SVX01D-EN 11

stage to the circuit board power requirement. For example, a Series F unit containing magnetic contactors with three stages of reheat would consume 42 VA.

p. 13 through Figure 5, p. 16 for wiring of output devices.

Zone Sensor Wiring

Location and Mounting

A zone sensorin each control zone should belocated in the most critical area of the zone. Sensors should not be mounted in direct sunlight or in the area’s supply air stream. Subdivision of the zone may be necessary for adequate control and comfort.

Avoid mounting zone sensors in areas subject to the following:

• Drafts or “dead spots” behind doors or corners

• Hot or cold air ducts

• Radiant heat from the sun or appliances

• Concealed pipes or chimneys

• Unheated or uncooled surfaces behindthe sensor such as outside walls

• Air flows from adjacent zones or other units

Wiring

Each unit must be controlled by a zone sensor that is designated specifically for use with the UCM control.Field wiring for the zone sensors must meet the following requirements:

• Must be 14 to 18 AWG

• Refer to the sensor instructions for terminal connections.

• If local codes require enclosed conductors, the zone sensor wires should be installed in conduit. Do not

UCM 4.2 Installation andWiring

route zone sensorwires in conduitwith 24VAC or other high power conducting wires.

Multiple UCM’s Per Zone Sensor

Up to three (3) UCM’s may be connected to a single zone sensor and thumbwheel set point.

• Connect terminal connectionsTB3-1,TB3-2, andTB33 in parallel (i.e. daisy chain) from the master UCM to the slaved UCM(s).

Note: Proper polarity must be maintained.

• Cut jumper wires W1 and W2 on the slaved UCM’s (never cut jumper wires W1 and W2 on master UCM).

Multiple UCM’s per Auxiliary Duct

Communication Wiring

Communication Link Wiring

The “Communication Link” is the communication wiring

betweenTracer Summit® and all VAV box Unit Control Modules (UCM).Tracer Summit can be connected to the UCM communication link in a“daisy chain” configuration.

Note: It is not necessary for each UCM to beconnected to

the line in sequential order by address. Also, multiple communication links may be run and terminated atTracer Summit. However, a consistent, documented wiring path will help troubleshoot communication problems after installation.

Field wiring for the communication link must meet the following requirements:

1. Communication link wiring must be at least 18 AWG twisted shielded pair wire. Shields must be grounded atTracer Summit or Central Control Panel (CCP) only. More than one ground reference will cause communications failures. Shields must be daisy chained.Tape the shield at the lastVAV UCM to prevent any connection between the shield and ground. Wire specifications are as follows:

Plenum Cable

Stranded, tinned copper insulated with extruded FEP. Conductors cabled and shielded with overall aluminum/Mylar tape and stranded, tinned copper drawn wire. Extruded jacket, 300 volt, 150°C NEC 7252 (b) class 2, type CL2P, 25 pF/ft.

4. A maximum of 63 UCMs can be connected to each COM Link. Daisy chaining is a typical configuration. “STAR” chaining is also acceptable.

Note: Polarity is extremely important and must be

observed on communication link connections.

5. At the VAV box, communication link wires must be connected toTB2-1, 3 (+) andTB2-2, 4 (-) terminals on the UCM.

6. Verify that the UCM address is properly set (DIP switch SW1). See

Table 6, p. 13 for proper DIP switch settings.

DIP Switch Settings

DIP Switch SW1 contains six switches for addressing the UCM.These switches allow a user to set a unique communication address for each UCM. Each UCM on a given communication link must have a unique address in order forTracer Summit or the CCP to communicate to it. Refer to Table 6, p. 13 for UCM 4.2 DIP switch settings.

Note: When using Rover™ service tool to communicate

to the UCM, you must add 64 to the DIP switch address. For example, a UCM with the DIP switch address set to 1 would be UCM Number 65 in Rover.

Wireless Zone Sensor

Overview

TheTraneWireless Zone Sensor set includes a sensor and

a receiver that work together to provide the same functions as the equivalentTrane wired sensor (#4190-

1090), such as the standard 10 k temperature input (with the exception of the communication jack). No further software or hardware is necessary for site evaluation, installation, or maintenance.

The sensor transmits the zone temperature, all zone

temperature setpoint functions, timed override Occupied

Figure 6. Outside dimensions for sensor

2.90 in (7.35 cm)

(On) and timed override Unoccupied (Cancel) information to the receiver.The receiver electrically reproduces the zone temperature resistance, all zone temperature setpoint function resistances, and timed override On and timed override Cancel information as sent by the sensor.

Dimensional Diagrams

See Figure 6,p. 17 and Figure 7, p. 18 fordimensions of the

Wireless Zone Sensor set.The dimensions are the same

for both the sensor and the receiver.

1.08 in (2.75 cm)

4.78 in (12.14 cm)

2.62 in (6.65 cm)

Note: The dimensions are the

same for both the sensor and the receiver.

Setting the Address, Mounting,

Wiring, and Associating the

Receiver and Sensor

The following procedure list shows the recommended

order for installation:

• Choosing a location for mounting the sensor

• Settingthe rotary address switches on the receiver and on the sensor

• Replacing and securing the receiver cover

• Powering the sensor and associating the sensor to the receiver

• Applying power to the receiver

• Testing signal and battery strength

• Disassociation

Note: The dimensions are the

same for both the sensor and the receiver.

Choosing a Location for Mounting the Sensor

Placement of the receiver and the sensor set is critical to proper operation. In most installations, distance is not the limiting factor for proper radio signal quality. It is more greatly affected by walls, barriers, and general clutter. For best radio transmission range and reliability, wherever possible, mount the receiver andsensor in line of sight.Try to minimize the number of barriers between the pair of devices. In general, sheetrock walls and ceiling tiles offer little restriction to the propagation of the radio signal throughout the building; concrete or metal barriers offer the most restriction.Thetransmission range for the sensor is as follows:

• Open range: 2,500 ft (762 m) (packet error rate = 2%)

• Usable range: 200 ft (61 m)

• Typical range: 75 ft (23 m)

Ambient considerations

Avoidlocations that are outside theoperating temperature

and humidity range (see Table 14, p. 48).

Location Considerations for the Sensor

When selecting a location for the sensor, consider both

thermal and radio transmission characteristics of the location.

Thermal considerations

• Avoid areas of direct sunlight

• Avoid areas in the direct air stream of air diffusers

• Avoid exterior walls and other walls that have a temperature differential between their two sides

• Avoid areas close to sources of heat such as sunlight, appliances, or other equipment

• Avoid drafty areas

• Avoid dead spots behind doors, projection screens, or corners

Radio transmission considerations

• Avoid placing the sensor inside metal enclosures

• Avoid radio transmissions through thick, solid concrete walls

Setting the Rotary Address Switches on the Receiver and the Sensor

Note: To expedite the installation and association

process, set the addresses before applying power to the receiver.

The process of establishing communication between the

receiver and sensor is referred to as association.The receiver and the sensormust have their rotary switches set to the same address in order to enable communication between the two devices (see Figure 8, p. 19). Important limitations are as follows:

• Only one associated receiver/sensor set can communicate within the reception range of the wireless system.

• It is not possible to associate more than one sensor to a receiver, nor is it possibleto associate morethan one receiver to a sensor.

• Avoid metal barriers between the sensor and receiver, such as plastered walls with metal lathe as they will decrease radio signal quality.

Setting the Receiver Address

1. Using a small screwdriver, set the three rotaryaddress switches (locations S1, S2, S3) on the receiver (Figure 8, p. 19) to an address between 001 and 999.

Note: Do not use 000 as an address for installation. If

you set the receiver address to 000, it will:

– Return the receiver outputs to their factory

defaults indefinitely (zone temperature and setpoint outputs: 72.5°F [22.5°C])

Setting the Sensor Address

1. Using a small screwdriver, set the three rotaryaddress switches (locations S1, S2, S3) on thesensor (Figure 8,

p. 19) to the same address used for the receiver it is to

be associated with.

2. Make a notation of the address and locationwhere this sensor is to be mounted.

Note: Do not use 000 as an address for installation. If

you set the address to 000, it will:

– Remove all association knowledge

– Revert to a low-power hibernation mode.

– Send a disassociation request to the receiver. If

the sensor and receiver are associated and communicating at the time the sensor is set to 000 and theTest button is pressed, the receiver will also become unassociated and will be available for re-association.

• Read the switches from left to right in the order in

which they are numbered (S1, S2, S3).

• Zero is at the 9 o'clock position.

3. Make a notation of the address and location of the sensor.

Factory Wiring of the Receiver to the VAV UCM

The required power for the receiver is 24 VAC or 24 Vdc

and is less than 1 VA.The receiver is designed to be powered by the VAV UCM controller.

Note: A dedicated transformer is not necessary or

advised.
