Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment.

Introduction

Read this manual thoroughly before operating or servicing this unit.

Warnings, Cautions, and Notices

Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.

The three types of advisories are defined as follows:

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 situation that could result in 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 handling of all refrigerants-including industry replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.

Important 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 according to local rules. For the USA, 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.

Unit Information

Single Duct VAV Units

The basic unit consists of a sheet metal casing with an air valve, which is used to modulate the air being delivered into the occupied zone. The unit is designed to modulate either cooling or heating air between 40°F and 140°F (4.44°C and 60°C). Air enters the air valve through the round or rectangular inlet and exits into the sheet metal casing to be distributed to the zone either through integral round outlets in the casing or through rectangular duct attached to the discharge of the unit.

The basic unit can also be ordered with factorymounted electric or hot water heating coils attached to the discharge.

These re-heat units are used primarily to reheat air-tozone temperature when the load in the occupied space is low.

Primary air is modulated through the VariTrane™ air valve by rotating the damper blade. All air valves have a round/rectangular inlet for easy fit-up with incoming duct work.

Typical Single Duct VAV Units

Figure 1. Typical single duct unit; VCCF VCWF, VCEF

VAV-SVX08G-EN


Dual-duct units provide two air valves: one as heating primary air and the other as cooling primary air. Both discharge into the common outlet, which leads to the zone being controlled. See .

Units are provided with a slip and drive rectangular duct connection or can be ordered with integral outlet plenum.

15

Sequencing of hot and cold air valve is dependent on job requirements. One typical control is valves working in conjunction to respond to zone temperature.

When the cooling valve becomes fully closed or reaches a specified minimum, the heating valve will begin to modulate or vice versa. The typical result is that air flowing to the zone varies from maximum down to a minimum and back up to maximum as load varies and controls would cause one air valve to close and the other to open.

Another typical application is when the unit provides a constant volume to the zone. When the zone sensor is tied directly to the heating valve, it will modulate the heating valve according to the zone temperature.

When the heating valve is fully closed or there is a call for cooling in the zone, the cooling valve will be at constant supply. As the space becomes too cool, the heating valve will modulate open, decreasing the cooling valve flow. The typical result is that the air flowing into the zone stays at a constant flow whether the unit is heating or cooling.

Factory-installed Trane unit controls available include;

• UC400 — one required per unit

• VV550 — two required per unit

• UCM — two required per unit

Hot water coils are connected to either the plenum inlet or on the discharge on parallel units, and to the discharge of series units.

Chilled Water Sensible Cooling

Terminal Units

Chilled water sensible cooling terminal units are available with or without re-heat. Refer to the following figures.

Figure 7.

Chilled water sensible cooling unit

The fan on a series unit runs continuously whenever the main air handler unit is in operation. There are three (3) methods to start the fan: 1) remotely, 2) by a duct pressure switch, or 3) by a combination of both.

The particular fan control method may vary from unit to unit, depending upon job needs.

Typically, heater is off while air valve modulates primary air and responds to zone temperature. If zone temperature decreases to the point where a decrease in primary air will not maintain the desired temperature, the re-heat will be activated to increase the temperature of the discharge air.

On a parallel unit, the VariTrane™ air valve delivers primary cooling air to the unit outlet. When the space temperature decreases beyond air valve control, the fan is turned on as the first stage of heat. The fan delivers plenum air from above the occupied space to the unit outlet, which is mixed with primary air and delivered to the occupied space.

airflow into the occupied space. In order to prevent primary airflow from exiting through the fan when the fan is not running on a parallel unit, a back draft damper is provided. When the fan is not running, the efficiency of this system is the same as a standard single-duct VAV unit.

Typically, the control systems applied to parallel units cause the air valve to close to zero or a minimum flow before the fan is activated. After the fan is activated, the optional heat will be activated upon further reduction in zone temperature. Therefore, minimal primary air is mixed with the heated air.

VariTrane™ fan-powered unit fan sizes 02SQ–05SQ and 08SQ–10SQ were performance tested at .12 in. w.

g. and sizes 06SQ and 07SQ were tested at .15 in. w.g.

Units are not designed to operate without ducts and below these tested static pressures.

Figure 8.

Chilled water sensible cooling unit with hot water coil

Figure 9.

Chilled water sensible cooling unit with electric heat

The function of the Trane chilled water sensible cooling terminal units is a little different than traditional VAV

Terminal Units. These terminal units are part of a distribute outdoor air to an air valve on each terminal unit to meet the ventilation requirements of the zone.

Each terminal unit is also equipped with a cooling coil mounted on the plenum inlet. Recirculated air from the

17

plenum (or directly from the occupied space) is drawn in through this cooling coil by the local fan. This cooled air is then mixed with the conditioned (cooled, dehumidified, heated, or humidified) outdoor air from the dedicated OA unit, and distributed through the downstream ductwork to the zone.

In most applications, the water supplied to this local cooling coil is controlled to a temperature above the dew point in the zone. This avoids moisture in the air from condensing on the coil, so it operates dry and provides only sensible cooling. All the dehumidification must then be provided by the dedicated outdoor-air unit. Trane chilled water sensible cooling terminal units are built with a drip pan located beneath the cooling coil, with a moisture sensor installed in it, to detect and prevent any moisture from getting on the ceiling beneath the units or into the occupied space below. These terminal units can be configured with either a hot water coil or electric heater mounted at the unit discharge.

Due to their weight, the VAV terminal units should be suspended from the uppermost ceiling, independent of the false ceiling grid. See

“Weights,” p. 27

for unit weights. Suspension devices are to be supplied by the installer. Units must be installed level and upright.

Failure to level the unit properly may prevent proper operation of the controls and/or terminal unit. Units are not designed to be installed vertically. Consequently, this will also void the U.L. ratings and any warranty on the unit.

Depending upon the size and weight of the single-duct unit, it may be capable of being supported by the ductwork that is connected to it. No hanger brackets are provided on these units since the unit should be supported by means of a hanger strap. The hanger strap should be secured directly to the unit casing as shown above.

• For cooling only single-duct units or single-duct units with hot water coil, the unit may be rotated

180° for opposite side connections.

• For units with electric heat, the unit can be flipped to either RH or LH connection orientation if model number digit 22 Electrical Connections = F.


Dual-duct units should be supported by either hanger straps or by using a threaded rod in conjunction with the hanger brackets that are provided on the unit.

• Single Duct 1-row coils (inlet sizes 05, 05, 06,

08 or 10 only)

• Low Height Parallel Inlet 1-row

• Low Height Parallel Discharge 1-row

All others require a 0.875” OD water coil piping connections.

single row coils. For multi-row coils, always plumb in counter flow orientation.

• Water inlet is always on the airflow downstream side of the hot water coil.

• Water outlet is always on the upstream side of the hot water coil.

3. Care should be taken to properly support the water coil piping connections while connecting the adjoining pipe.

4. It is recommended that piping to the water coil should be done after field-mounted controls, external insulation, and ductwork connections have been completed.

extensions to the water coil connections unless supported.

Unit Accessibility

• Single-duct and dual-duct units provided with hot water reheat have an access panel located on the side of the water coil. All other single-duct and dualduct units are provided without access, as all functioning components are external to the unit.

• Fan-powered terminals are provided with a sliding side access.

• Low-height terminal units have a removable bottom panel.

Clearances

For proper service, it is recommended that at least 36” of side clearance be provided to service and access single-duct and dual-duct terminals units.

• Fan-powered VAV units have a plenum inlet that must be clear of obstructions. Allow at least 36” of clearance in front of the side access and plenum opening.

• Low-height fan-powered terminals require the same plenum clearance requirement that applies to the standard fan-powered units. However the access to the internal components is located on the bottom of the unit.

It is also recommended that 6” of clearance be provided to the top and bottom of all the units.

controls should be 36” for all models except units with 575-volt electric heaters, which require

48” of clearance. NEC ™ and/or local codes override all clearance requirements.

Mounting Actuator

tighten the actuator set screw per the manufacturer’s instructions. Failure to follow the manufacturer’s specifications may result in unit malfunction.

Trane offers a factory-mounted actuator with a 90second drive time. The actuator drives 1°F per second.

A field-installed actuator may be used if desired. The actuator shaft has a 0.5 inch diameter and is designed to travel clockwise to close the damper and counterclockwise to open the damper. There is an indicator on the end of the actuator shaft that can be used to determine the position of the damper.

Stand-alone Units

Stand-alone UCM 4.2

When there is no communication to the UCM control and the unit is in the stand-alone mode the control action is determined by the auxiliary temperature sensor located on TB3-5 and TB3-6 terminals on the

UCM board. In order for the auxiliary sensor to determine the control action (heat, cool) it must be located in the supply duct, upstream of the VAV unit.

The auxiliary temperature is then compared to the zone temperature. If the supply air temperature is 10 degrees above the zone temperature, then the control action will be heat. If the supply air temperature is less than or equal to the zone temperature, then the control action will be cool. If the supply air temperature is between the zone temperature and the zone temperature + 10ºF (5.5°C) [zone temperature < supply air temperature < zone temperature + 10ºF] (5.5°C), the control action remains the same and the UCM controls to the minimum flow set point. If an auxiliary sensor is not installed the UCM will retain the last control action in effect.

Stand-alone VV550 LonTalk Control

When there is no communication to the VV550 control and the unit is in the stand-alone mode the control action is determined by the auxiliary temperature sensor located on TB3-5 and TB3-6 terminals on the

VV550 board. The control must also be configured through the Inputs Tab of Analog Input 4 as Primary

Supply Air Sensor. In order for the auxiliary sensor to determine the control action (heat, cool) it must be located in the supply duct, upstream of the VAV unit.

The auxiliary temperature is then compared to the zone temperature. If the supply air temperature is 10 degrees above the zone temperature, then the control action will be heat. If the supply air temperature is less than or equal to the zone temperature, then the control action will be cool. If the supply air temperature is between the zone temperature and the zone temperature + 10ºF (5.5°C) [zone temperature < supply air temperature < zone temperature + 10ºF] (5.5°C), the

Stand-alone UC400

When there is no communication to the UC400 control and the unit is in the stand-alone mode the control action is determined by the auxiliary temperature sensor located on AI5 terminals on the UC400 control.

This input may have to be changed from AI4 (Discharge

Air Input) as wired from the factory. In order for the auxiliary temperature sensor to determine the control action (heat, cool) it must be located in the supply duct, upstream of the VAV unit. The auxiliary temperature is then compared to the zone temperature. If the supply air temperature is 10°F above the zone temperature, then the control action will be heat. If the supply air temperature is less than or equal to the zone temperature, then the control action will be cool. If the supply air temperature is between the zone temperature and the zone temperature +10°F (5.5°C)

[zone temperature < supply air temperature < zone temperature +10°F] (5.5°C), the control action remains the same and the UC400 controls to the minimum flow set point. If an auxiliary sensor is not installed the

UC400 will retain the last control action in effect.

Stand-alone UC210

When there is no communication to the UC210 control and the unit is in the stand-alone mode the control action is determined by the auxiliary temperature sensor located on AI3 terminals on the UC210 control.

From the factory, this input is configured for discharge air temperature and needs to be field reconfigured as supply air temperature using Tracer® TU. In order for the auxiliary temperature sensor that is configured for supply air temperature to determine the control action

(heat, cool) it must be located in the supply duct, upstream of the VAV unit. The supply air temperature

Bottom Access

An optional bottom access can be provided in the casing of fan powered series or parallel terminal unit.

The 22-gauge door is lined with 1”, 26-gauge, dual wall insulation and thermal lined with 1” – 1 lb. density fiberglass insulation with a 3.85 R-value.

Each door includes 4 to 6 cam locks that are used to secure the door to the casing.

The cam lock engages a metal encapsulated frame on the unit that encloses the unit insulation to prevent air erosion.

The cam lock engagements are interlocked using a flat head screwdriver. Once unlocked, the entire door assembly can be removed for access.

Adjusting the SCR Motor Speed

Control

In order to make units more convenient and efficient to balance, an SCR (silicone control rectifier) is provided as standard on all fan-powered units.

The SCR is located on the side of the fan control box.

To adjust the speed of the motor, the external knob must be rotated either clockwise or counterclockwise depending on the desired speed adjustment.

There is an internal potentiometer setting on the SCR controller that can be accessed by removing the control box cover. This internal potentiometer is set at the factory to the specific motor voltage.

It may be necessary to adjust this in the field depending on the building power factor.

Figure 26.

Electrically Commutated Motor

(ECM)

Figure 27. ECM control board of the fan motor.

Trane offers an energy efficient ECM motor as a motor option. Balancing of an ECM motor is accomplished through electronic control adjustments on the ECM control board. The following tables provide potentiometer settings. Other potentiometer settings can be determined either by interpolating from these tables or by using the following equation:

• CFMsetting = CFMmin + {(Potentiometer Setting) x

[(CFMmax - CFMmin)/100]}

There is an LED on the ECM control board, which will blink one time for every 100 CFM of motor setting. For example, the LED on a unit set for 790 CFM will blink seven (7) times. The LED on a unit set for 800 CFM will blink 8 times.

properly. This feature does not indicate at what speed the motor is actually running.

The ECM must be load tested. In other words, the fan must be connected to properly test the ECM.

Maintenance

Periodic maintenance of the VariTrane™ product is minimal, but necessary for efficient operation. Routine maintenance consists of inspecting/replacing the air filters of the fan-powered terminals.

Motors

Both the Permanent Split Capacitor( PSC) and the

Electrically Commutated Motor (ECM) require no lubrication during its normal life of operation.

Fan Wheel

Routinely inspect the fan wheel for dirt or debris and cleaned as necessary.

Filter

Routinely inspect and/or replace the filter on fanpowered terminals depending on the environmental conditions of the plenum.

Filter Change Out

• To remove the filter, turn each of the filter retaining clips 90° (CW or CCW)

• Remove the filter and replace with new filter of the same frame size.

• Return the filter clips to their retaining position by turning them 90° (CW or CCW) back to their original position.

Water Coil

• Periodically inspect water coils and clean fins.

• Water coils are provided with an access panel as standard to assist with inspection and cleaning.

Fan Motor Replacement

Diisscco nn arrtt//rru n ne nttss p de d b ad diittiio ap orrss,, sse ap prro otth errss,, rre

Figure 47.

Standard motor removal

Standard height fan-powered series and parallel fan motors are replaceable through the filter opening and the standard sliding side access panel. To access the fan motor, the fan housing must be detached by removing the mounting bolts that hold the housing to the fan board. Removing the entire housing allows the fan motor, fan housing, and fan wheel to be re-aligned on a workbench or floor and prevent any possible fan wheel rubbing that may occur. Removing the housing will provide access to the motor shaft set screw that holds the fan wheel to the motor shaft.

The low-height fan assembly was designed with an inlet ring that assists with removal of the fan motor. To

67 VAV-SVX08G-EN

access the fan motor assembly, the bottom panel must be removed. The inlet ring is held in place by six (6) bolts and three motor mount bolts. Remove these bolts to release the motor and fan wheel from the fan housing.

Figure 48.

Low-height motor removal

SCR Assembly

SCR solid state relays are used to switch a single heater stage on and off. An intelligent (Master) relay is used for all single phase applications. For three phase applications, a Master-Slave configuration is used to switch two legs of three phase power to the heater stage. The Master Relay controls one leg independently, and provides a control signal to the

Slave Relay, which controls the second leg.

Figure 49.

Typical heat sink fin orientation

Every Master or Master/Slave relay combination is mounted on a heat sink to prevent the relays from overheating during normal operation. The SCR assembly must always be mounted with the heat sink fins oriented vertically (see above) with a minimum clearance of 0.5" on all sides of the heat sink for cooling. Where additional cooling slots are provided in the heater, the VAV unit must be mounted with a minimum of 1" clearance in front of the slots.

When the 0-10 VDC control voltage is present at the

Master relay in both single and three phase applications, an ON indicating LED light on the Master relay will blink continually (approximately 0.5 seconds on, 1.0 seconds off). If the load side voltage is also present at the relay(s), the Master relay LED and the

Slave relay LED blink rate will increase as the control signal increases. When the control signal reaches a maximum of 10VDC, all LEDs will be lit continuously, indicating that the relays are full-open and continuously conducting. If the control signal is present in three phase applications while the load side voltage is not, only the Master relay LED will light and the blink rate will be constant.

If the SCR assembly does not appear to be functioning properly, verify that all required voltages are present and all that all wiring is properly connected. If all these conditions are verified, and the SCR LED does not light and/or the SCR relay does not conduct, the entire SCR heat sink assembly should be changed out. Individual

Master or Slave relays should not be replaced.
