Introduction

The Trane Classroom Unit Ventilator

Academic performance of U.S. students depends, in part, on the ability to create a comfortable

learn-friendly surrounding. Being too hot or too cold could hinder a students ability to achieve

academic excellence.

Seasonal changes, mechanical/building disrepair, and even class attendance provide real

challenges to HVAC mechanical systems. The only thing consistent about today’s classroom is its

ability to constantly change. With this in mind, Trane introduces a NEW classroom unit ventilator

design to support today’s changing environment.

Features and Benefits

Fit and Finish

Equipment Size

The vertical unit ventilator delivers from 750 cfm to 1500 cfm. It is physically sized to fit the

replacement or new construction application.

Cabinet Finish

The unit cabinetry is made of a durable industrial grade metal to withstand even the most rigorous

classrooms. A smooth/glossy, appliance grade paint treatment increases the aesthetics of the

equipment while making it durable and easy to maintain.

Access

A three panel front access of the unit ventilator is ergonomically safe for lifting/removal, and allows

speedy set up during field commissioning. This design allows for the end pocket of the unit

ventilator to be open while the fan (airside) section stays closed. The panel design supports a clean

fit and finish while providing effortless access for filter change-out.

Top access to the unit mounted fan speed/sensor option was developed with the teacher or

administrative staff in mind. Access to the sensor may be made through a lock/key, or through an

easy open door.

Install-ability, Service-ability and Maintain-ability

Spacious End Pockets

Easy access to piping and controls is made through the roomy equipment end pocket design. The

coil headers and drain connections are made within the unit chassis, freeing-up valuable space in

the end pockets for piping or field add-ins. This also grants a tighter seal to prevent air leakage.

The roomy end pocket design Figure 4, p. 6 allows for application requirements such as an optional

auxiliary drain pan. The auxiliary pan may be placed under the factory or field piping package.

Features and Benefits

Sliding Fan Deck

Convenient access to the fan motor and fan wheels for maintenance and serviceability is made in

part of the easy-slide design of the unit ventilator fan board, Figure 5. The fan board assembly

offers hassle free access to the contractor or maintenance technician. As an added benefit, Trane’s

unit ventilator includes Electronically Commutated Motors (ECM) as standard.

Energy Efficiency

Trane has a commitment to providing premium quality products that has led to the exclusive use

of Electronically Commutated Motors (ECM) in all unit ventilator models. These brushless DC

motors incorporate the latest technology for optimized energy efficiency, acoustical abatement,

maintenance free and extended motor life. Each motor has a built-in microprocessor that allows

for programmability, soft ramp-up, better airflow control, and serial communication.

• Trane units equipped with ECMs are significantly more efficient than a Permanent Split

Capacitor (PSC) motor.

• Lower operating costs on average of 50 percent (versus a PSC motor).

• The Reduced FLA option allows units to ship with a nameplate FLA rating much lower than a

typical ECM unit.

Filters

Trane unit ventilators utilize an off-the-shelf filter design to reduce or eliminate local stocking of

filters in the school. See “General Data,” p. 25 for standard filter sizes.

Note: High efficiency options, MERV 8 and MERV 13, are available. These filters provide greater

resistance and dust holding capabilities.

Hinged Control Box

The hinged control box design maintains easy access to the electrical for connection while

supporting less potential for damage on the job site from the different construction trades.

Features and Benefits

Piping

Hydronic piping for the unit ventilator may be factory installed or field provided. It fits freely inside

the unit end pockets, supplying quick hook-up during the installing phase. The motorized valves

include a trouble-free, pop-top allowing the maintenance or service technician access to the motor

without removing the valve body from the piping package.

IAQ Features

Indoor air quality (IAQ) has become a top priority in classroom design. Giving students a healthy

place to learn and develop is crucial in every school district. It is also crucial to maintaining the

building’s overall construction and furnishings. Several features of Trane’s unit ventilator attribute

to improved IAQ.

Removable Drain Pan

The unit ventilator drain pan is dual sloped for effective condensate removal. This non-corrosive

pan eliminates the problems associated with leaking or standing water and is removable for

cleaning.

Ease of Maintenance

Internal components such as the fan and coils are accessible for visual inspection and cleaning.

Maintaining a clean system increases the efficiency of the unit and is important to good,

sustainable indoor air quality.

This design also places the coils farther away from the outside air opening, virtually eliminating the

potential for coil freezing and the added hassles of nuisance freeze-trips.

OA/RA Damper Design

The outside/return air damper is a one-piece design which is linkage free resulting in a superior air

seal (see Figure 4, p. 6). This results in lower infiltration of outside air during off cycles thus

lowering the risk of freezing equipment in the winter or the intrusion of humid air into the building

during the summer.

OA/RA Actuator

The OA/RA actuator provides true spring return operation for positive close-off of the OA/RA

damper. The spring return system of the actuator closes the outside damper if power is lost to the

building. When ordered with factory controls, the actuator is a 3-point floating design. A 2 to 10-Vdc

actuator is available when other than Trane controls are specified.

Features and Benefits

Unit Filter

Each classroom unit ventilator comes equipped with a standard-size throwaway filter to support

job site installation and start-up. However, the Trane unit ventilator is designed to accommodate

the use of a MERV 8 or MERV 13 high capacity filter to provide greater filtration of airborne

contaminants.

Dehumidification

Trane unit ventilators provide a broad range of dehumidification solutions. Active humidity control

involves monitoring and managing both the dry bulb temperature and the humidity in the

classroom. With this strategy, a reheat coil is placed downstream of the cooling coil to temper

(reheat) the cold, dehumidified air leaving the cooling coil to avoid over-cooling the space. Reheat

configurations are available in a variety of coil combinations.

Alternately, the Tracer™ UC400 or Tracer ZN520 controller can be configured to automatically

reduce the fan speed at part-load conditions. This helps improve the coincidental dehumidification

performance of the unit at part-load, and also lowers sound levels. To help ensure proper

ventilation in the classroom at lower fan speeds, the controller adjusts the outside air being

supplied to the classroom.

Economizer

One big advantage of a Unit Ventilator system is the ability to provide energy savings through an

economizer cycle. During mild seasons outside air is used to provide “free” cooling, thereby,

minimize or eliminate the need to run mechanical cooling equipment. To truly have an effective

economizer a Unit Ventilator must be able to bring in up to 100 percent of the design airflow

through the outside air damper opening. Trane Unit Ventilators are tested and certified to exceed

the industry standard, as defined by AHRI 840, for economizer effectiveness. This ensures the

school will realize the energy savings available through the economizer strategy.

Face and Bypass Actuator

The face and bypass damper actuator incorporates a direct couple design. It provides electronic

protection against overload. A limit switch is not included, nor required as part of the design. When

reaching the damper end position, the actuator automatically stops. The gears can be manually

disengaged with a button on the housing.

Acoustics

Quiet systems are extremely important in today’s classrooms. Trane offers many different system

solutions to balance the requirements of sound, cost, IAQ and efficiency. The Trane vertical unit

ventilator takes a comprehensive approach to delivering one of the quietest units available.

Fan and Blower Motor Assembly

Several innovative ideas have gone into the quiet design of the Trane vertical unit ventilator. The

fans diameters have been maximized to reduce the motor rpm and thus lower the noise, while still

maintaining the cfm requirements to support ventilation and capacity requirements. The unique

direct-drive fan and blower design diminishes vibration from occurring further ensuring quiet

operation.

Fan Speed Control

Trane provides the capability to vary airflow for suitable applications either with three speeds or

with a 0–10 Vdc input. This lowers the sound in the space and improves the dehumidification in the

cooling season at part-load. With field installed controls, this is accomplished with a unit-mounted

manual fan speed switch (allowing either 2- or 3-speed control) or variable speed control with a

0–10 Vdc input. ECM controls provide a soft ramp between speed changes—a significant

contributor to overall quiet operation.

UV-PRC003-EN 9

Features and Benefits

With the inclusion of the Tracer UC400 unit controller, the speed of the fan is infinitely varied

automatically in response to the load condition in the space. The controller also will adjust the

outside air being provided to properly ventilate the classroom at the lower airflow conditions.

Quiet Blow-Through Design

The Trane blow-through unit design enables additional sound attenuation by eliminating the fan

noise from entering the space directly. The position of the internal components is optimized to

enhance The performance and casing construction of Trane vertical unit ventilators further adds

to this acoustically superior design.

Certification/Standards

Comfort, energy and IAQ are all major issues that need to be woven into today’s school designs.

Therefore, it is important that designers of these systems have accurate information to make

system decisions. That is why the industry has developed performance standards and certification

programs which ensure that the equipment information provided to the design community is

correct and comparable across different manufacturers. The following list of certifications

identifies the commitment by Trane to providing the highest quality equipment and information to

our customers:

• AHRI-840

• ETL

• Tested in accordance to AHRI 350 (acoustics)

Application Considerations

A Choice in System Design

The beauty of the classroom unit ventilator goes beyond its ability to heat and cool. The unit

ventilator design provides an opportunity to create a comfortable atmosphere for living, learning

and playing, while supporting energy efficiency savings. Some of the featured benefits of a unit

ventilator are:

• Individual room control.

• Fresh air ventilation and filtration.

• Individual dehumidification sequences per zone.

• Energy savings solutions through economizing functions and Electronically Commutated

Motors.

• A choice in heating/cooling applied systems.

• And, because the equipment is mounted directly in the living space, expense associated to

installed mechanical ductwork may be avoided.

Wide Variety of Heating/Cooling Coils

Trane’s unit ventilator offers a wide variety of coil configurations to be used in many design

considerations.

In environments where cooling needs are of main interest, a two-pipe coil coupled with a chiller,

or a direct expansion coil joined with a condensing unit may be used.

For heat specific applications, Trane offers a two-pipe hot water only unit to be combined with a

boiler. Electric heat and steam options are also available for heating selections.

When there is seasonal heating and cooling, a two-pipe chilled water/hot water changeover system

may be applicable to the mechanical design. This system requires a chiller and a boiler to support

the changeover necessity. However, where space constraints may present a concern, the Trane unit

ventilator may be equipped with a direct expansion coil for cooling, with an auxiliary electric heat

coil, hot water coil, or steam coil for heating.

Four-pipe chilled water/hot water systems are also available. This system is typically applied when

both heating and cooling may be simultaneously called for in the school.

Building Automation

As part of the building automation system, the mechanical HVAC system equipment may be

optimized to lower energy consumption. By running only the mechanical devices that are required

to support the building load at a given time of day or night, true energy consumption savings may

be achieved.

Maintenance and service information through the unit sensing devices are easily defined and

cured with an automated system.

With factory shipped direct digital controls, installation and start-up of the system are more simple.

Condensate

Proper condensate trapping is required for the classroom unit ventilator’s with hydronic and direct

expansion coils (steam coils do not require a trapped condensate setup). In a properly trapped

system, when condensate forms during normal operation, the water level in the trap rises until

there is a constant flow of water through the pipe. It is imperative to maintain water in the trap, and

not allow the trap to dry out during heating season.

Equipment should be installed level to avoid condensate build-up around the coil.

Performance

Application of this product should be within the catalogs airflow and unit performance. The Trane

Official Product Selection System (TOPSS™) will aid in the selection process for a set of given

Application Considerations

conditions. If this program has not been made available, ask a local Trane account manager to

supply the desired selections or provide a copy of the program.

The Importance of Air Quality

Indoor air quality (IAQ) should be considered a top priority in the school environment. School

institutes contain a diverse day of activities that have a potential for air impurity sources including

cafeterias, art and science classrooms, vocational education areas, pools and locker rooms. Proper

ventilation and filtration of these spaces can pose some challenges.

Occupant density in classrooms is much higher than that found in office or retail spaces. The

amount of outdoor air required to ventilate a classroom is based predominantly on the number of

students expected to occupy the space. Students also move in large groups, frequently throughout

the building, resulting in widely varied thermal loads within the zones. To compound the situation,

a classroom mechanical system is typically run for 9 months of the year, and vacated for 3 months

(either by turning up or off the HVAC system). To increase the IAQ challenge even more, building

construction techniques that help reduce energy costs, also tightly seal the school. This can lead

to uncirculated/unfiltered air.

Ventilation

Ventilation is an important factor in the maintenance of healthy air. In a poor ventilated school

building, fumes and vapors are not properly exhausted allowing particles to develop. A healthier

building is a building where the air is exchanged more frequently and properly filtered. Through

ventilation, stale indoor air is exhausted and fresh treated outdoor air is drawn into the building.

The amount of ventilation air required is established by building codes and industry standards.

Most building codes reference ASHRAE Standard 62–Ventilation for Acceptable Indoor Air

Quality–as the minimum requirement for ventilation system design. Architects, engineers and

contractors utilize this standard when determining and calculating the type of load the building

environment will place on the mechanical system.

Trane Unit Ventilators Support Indoor Air Quality

The Trane unit ventilator is tested and designed to exceed ASHRAE Standard 62. This includes the

use of a higher efficiency filtration to help introduce proper levels of “fresh” diluted air for

contaminant removal.

Application Considerations

Beyond the ventilation and filtration performance of the classroom unit ventilator, maintenance of

the HVAC system is a must. Several enhancements placed on the Trane unit ventilator to support

superior IAQ performance include:

• Coil presentation allows for ease of maintenance and cleaning.

• A dual sloped non-corrosive drain pan (removable) helps keep moisture in the system to a

minimum.

• Ultra low leak damper that results in a fixed air seal of the damper assembly.

• Air exchange performance that goes beyond code while maintaining the AHRI-840 certification

for economizing requirements.

• An upgrade-able MERV rated filters help reduce contaminants and increase filtration.

• Side-wall power exhaust support system to help remove the stale air from the classroom and

better support the air exchange.

• Energy recovery unit ventilator to further pretreat and dehumidify the fresh air before it enters

the classroom unit ventilator.

• Options for improved dehumidification at part-load, including automatic fan-speed control,

face and bypass dampers, and active humidity control through reheat.

A Choice in Energy Optimization

The energy consumption of a unit ventilator system can be significantly reduced through the use

of an economizer cycle. To better understand the basic function of how an outside air economizer

works, it is important to fully understand how it operates.

The economizer functions by opening an outside air damper, and bringing cooler outside air into

the space. The economizer cycle is controlled with a modulating damper motor, which opens at

specified increments dependent upon readings from outside air sensors.

Economizers also utilize a return-air damper that closes as the outside air damper opens.

Depending on the room requirements, the modulating damper motor may mix the return air with

the outside air to provide the maximum energy cost efficiencies without sacrificing comfort.

When the room thermostat calls for cooling, the economizer control provides the right mix of

outside and return air to cool the classroom. The equipment’s airflow is generated from both fan

energy and the economizing dampers. This design supports optimum ventilation and provides the

greatest energy savings. As the outside air temperature rises (typically above 55°F), the outside

damper closes to the minimum position, activating the second cooling stage on the room

thermostat—the cooling-generating device (compressor, water pump, chiller, cooling tower). The

return-air and outside air dampers modulate to support the discharged air temperature.

Dampers working together with the cooling coil is called integrated economizing, which allows a

unit ventilator to mix outside air with return air, delivering an energy-efficient, cost-savings

solution to a school.

Industry Standards

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) created the AHRI-840 standard for

classroom unit ventilators to provide a consistent method of rating the unit ventilators design

performance. To achieve AHRI-840 certification, the unit ventilator must be capable of providing a

minimum of 80 percent of its ventilation (airflow) through the outside air economizer function (see

Figure 8). This measurement ensures that the expected energy savings by the economizer is

realized in actual operation.

Only AHRI-840 certified equipment has been independently tested for compliance to the minimum

requirement. Trane was the first, and continues to be one of the few manufacturers that meet this

certification. By meeting this certification, the designer can be assured that the Trane unit ventilator

will perform with energy conservation in mind.

Energy Efficiency

UV-PRC003-EN 13

Application Considerations

Acoustics

A growing population, and an increase in economic pressure to maximize building footprints have

resulted in higher building occupancies and less space to place the HVAC equipment. Often times

the close proximity of the equipment—such as a floor mounted unit ventilator—may cause noise

related complaints. Reducing the likelihood of these complaints requires careful planning:

• In the equipment sizing (under sizing and over sizing could increase noise level).

• And equipment placement (absorption and number of sound sources in the room greatly affect

noise).

Room NC is the sum of all sounds entering the room. Its value is based on assumptions about the

room’s characteristics. Given the complexity of various building systems, it is extremely important

to assure that the design goals (commissioning) for classroom acoustics, IAQ, and moisture control

are met through all aspects of the space.

For example, it is not uncommon for a school to install unit ventilators that are manufacturer-rated

for a specified airflow (cfm), but which are not AHRI-840 certified. These units may ship with a fan-

speed setting that delivers a lower than specified airflow, perhaps to reduce sound levels. Without

an overall building design goal, these units will be installed without delivering the specified airflow

needed to support the fresh air circulation, and possibly compromise IAQ.

Note: Unless the equipment is tested at the specified airflow, it is extremely difficult to determine

whether the unit meets the specified sound level.

Trane’s unit ventilator will not compromise air quality to support a minor reduction in airflow noise.

We encourage our engineers to specify their airflow needs at full building load requirements. Fine-

tuning of the speed setting may be interchanged through the unit’s 3-speed fan sensor quickly and

easily. This mechanical feature ensures that the equipment supplies proper cfm to support IAQ in

the classroom, while giving complete control of equipment noise to the administrative staff.

Technology that Supports Acoustic Enhancements

Another solution to airflow noise is through Trane direct digital controls (Tracer UC400). With the

Tracer UC400 controller, an infinitely variable speed fan control for the unit ventilator delivers the

airflow output customized to support the cfm space needs. When less cfm is necessary to meet the

Figure 8. Unit ventilator economizer

Acoustics

Application Considerations

load of the classroom, the equipment operates at an optimum speed, keeping sound levels to a

minimum. Another solution for acoustically sensitive application is the option for “Low Acoustics,”

which uses the ECM technology to manage the fan speeds. However, if the room temperature rises

above the setpoint, the controller will switch to high speed for sustaining the space needs. As part

of this strategy, ventilation must also be considered. The Tracer UC400 controller will reposition

the outside air damper to confirm the minimum outside air cfm is met at both operating conditions.

This setup allows the unit ventilator to meet the space comfort condition, while providing a lower

sound level and proper ventilation.

Ventilation for Acceptable IAQ

Supplying proper ventilation to a classroom is challenging. The various rooms that make up a

school are forever changing in their proper ventilation needs. Building occupants and their

activities generate pollutants that heighten the ventilation requirements. And because of this

intermittent occupancy, the ventilation frequency of a classroom is constantly on the move.

Ventilation systems dilute and remove indoor contaminants, while mechanical heating and cooling

systems control the indoor temperature and humidity. Supplying an adequate amount of fresh air

to an occupied classroom is necessary for good indoor air quality. IAQ should be considered a top

priority in the school environment because children are still developing physically and are more

likely to suffer the consequences of indoor pollutants. For this reason, air quality in schools is of

particular concern. Proper conditioning of the indoor air is more than a quality issue; it

encompasses the safety and stewardship of our investment in the students, staff and facility.The

beauty of a classroom unit ventilator is its ability to provide heating, cooling, ventilation and

dehumidification as a single-zone system.

ASHRAE Control Cycles

There is a variety of control systems available today in unit ventilators. The exact method of

controlling the amount of outside air and heating capacity can vary. However, all systems provide

a sequence of operation designed to provide rapid classroom warm-up and increasing amount of

ventilation air to offset classroom load.

To help supply proper ventilation to these fluctuating heat gains, the Trane unit ventilator is

designed to provide rapid classroom warm-up and increasing amounts of ventilation air to offset

classroom overheating.

Figure 9. Equipment placement

Ventilation

UV-PRC003-EN.book Page 14 Tuesday, June 4, 2013 8:59 PM

UV-PRC003-EN 15

Application Considerations

ASHRAE Cycle I

All standard unit ventilator cycles automatically close the outside air damper whenever maximum

heating capacity is required. As room temperature approaches the comfort setpoint, the outside

air damper opens fully, and the unit handles 100 percent outside air. Unit capacity is then controlled

by modulating the heating element capacity.

ASHRAE Cycle I is typically used in areas where a large quantity of outdoor air is required to offset

the air being exhausted to relieve the room of unpleasant odors and particles.

ASHRAE Cycle II

ASHRAE Cycle II is the most widely used ventilation control. Similar to Cycle I, the outside air

damper is closed during warm-up. But with Cycle II, the unit handles recirculated air through the

return air system. As temperature approaches the comfort setting, the outside air damper opens

to admit a predetermined minimum amount of outside air. This minimum has been established by

local code requirements and good engineering practices. Unit capacity is controlled by varying the

heating output. If room temperature rises above the comfort setting, the heating is turned off and

an increasing amount of outside air is admitted until only outside air is being delivered.

ASHRAE Cycle II is a very economical control sequence often referred to as integrated

economizing. This design supports optimum ventilation and provides the greatest energy savings.

This is further proof of why AHRI-840 certification is important in minimizing energy consumption

through economizer performance.

Freeze Protection

The most important advantage the Trane blow-through design provides is additional protection

against coil freeze-up. In contrast, draw-through configurations allow little mixing of the return and

outside air stream while locating the coil very close to the outside air inlet. This process creates

“cold spots” on the coil which could lead to coil freeze-up.

With a blow-through design, face and bypass with isolation valve control is not necessary to

provide proper freeze protection to the unit vent. The placement of the coil above the fan allows

enough space for the coil to avoid “cold spots” that could cause freezing.

Application Considerations

Constant Volume System

A typical unit ventilator is a constant-volume, variable-temperature device. It uses a constant fan

speed and modulates water flow through a chilled water coil to maintain the dry bulb temperature

in the space based off of a setpoint. Outdoor air is introduced at the back of the unit ventilator, and

distributed with the supply air. At design cooling load conditions, a system controlled in this

manner typically has a leaving air temperature that is cold enough (and, therefore dry enough) to

sufficiently dehumidify the space, but its ability to dehumidify can decrease significantly at part-

load conditions.

When the sensible load in the space decreases (part-load), the constant-volume system responds

by raising the dry-bulb temperature of the supply air. In a chilled water unit ventilator, this is

accomplished by modulating a valve to reduce the rate at which water flows through the coil.

Figure 11 shows how this affects the supply air leaving the coil—the warmer coil surface that results

from less water flow provides less sensible cooling (raising the supply air temperature) and

removes less moisture from the passing air stream.

The sensible cooling capacity of a constant volume system decreases to match the smaller sensible

cooling load. Any latent cooling (dehumidification) capacity is purely coincidental, whether the

cooling-coil medium is chilled water or refrigerant. As the load diminishes, the system delivers

even warmer supply air. Some dehumidification can occur in this situation, but only if the sensible

load is high enough.

Some designers attack this problem by oversizing the unit ventilators. This does not solve the

problem; in fact, it can make the situation worse. Increasing the capacity of the unit ventilator may

also require increasing the supply airflow. A higher-than-necessary supply airflow results in

warmer supply air and, in non arid climates, less dehumidification. It’s important to understand,

this is not just a unit, coil, or fan-sizing challenge. Rather, it’s an issue of properly controlling the

system in a manner provides sufficient dehumidification at all operating conditions. Proper

dehumidification with terminal units is a matter of proper control.

Active Humidity Control

A common method used to address this part-load humidity control challenge in a constant-volume

system is active humidity control through supply air tempering (reheat). Active humidity control

involves monitoring and controlling both the dry bulb temperature and humidity in the occupied

space. Whenever the space humidity is below the preset upper limit (typically 60 percent relative

humidity), the system operates just like a normal constant-volume system. However, if the space

humidity reaches or exceeds the upper limit, the cooling coil control valve is driven open regardless

of the need for sensible cooling in the space. The coil over-cools the air, increasing the

dehumidification capacity of the system.

With this control sequence, a reheat coil is placed downstream of the cooling coil to temper (reheat)

the cold, dry air leaving the cooling coil in order to avoid over-cooling the space. The key to cost-

Dehumidification

UV-PRC003-EN 17

Application Considerations

effectively applying an active humidity control system is to use reheat only when it is needed. This

requires the sensing of both the humidity and temperature in the occupied space.

When the space humidity falls below the upper limit, the system returns to the standard cooling

mode and again operates as a traditional constant-volume system.

Basic components of Trane’s reheat system, include a (1) classroom unit ventilator with a main

coil and an auxiliary coil downstream, (2) the Tracer ZN520 digital controller, and (3) two

sensors, one for the temperature and one for relative humidity. Sensors may be located in the

zone, or in the return air stream.

If after hours operation is required, the addition of a building automation system (BAS) such as

Tracer Summit™ is recommended to coordinate the chillers, pumps, boiler and unit ventilators. It

also assures proper operation of the exhaust fans.

Reheat may come from new energy (electric resistance heat or boilers fueled by gas or oil) or

recovered energy.

Recovered energy reheat refers to the process of salvaging or transferring energy from another

process within the facility. In this case, the recovered energy is the by-product of a cooling process

which would normally be rejected or wasted. A common example may include a plate and frame

heat exchanger in the condenser water loop of a water-cooled chiller system.

Automatic Fan-Speed Adjustment

Reducing the fan speed (supply airflow) at part-load conditions is a way to improve the coincidental

dehumidification performance of a unit ventilator. The Tracer ZN520 digital controller can be

configured to automatically reduce fan speed when the sensible load is decreased, Figure 12, p. 18.

At full load, the fan operates at high speed and the control valve’s flow is wide open. As the cooling

load decreases, the controller modulates the valve to throttle the rate of chilled water flow through

the coil. At some point, based on valve position, the unit controller switches the fan to low speed.

Less airflow means that colder supply air is needed to maintain the target space temperature. The

control valve opens allowing the coil to remove more moisture from the passing air stream.

The controller will also adjust the outside air damper to help properly ventilate the classroom at

the lower fan speed condition.

Face and Bypass Dampers

Face and bypass control is a common and accepted method of capacity control.

The face and bypass damper, consists of a single blade installed immediately upstream of the

cooling coil. The bypass is sized to have the same pressure drop as the cooling coil so that a

constant air quantity can be maintained at all times during system operation.

Bypass control maintains the dry bulb temperature in the space by modulating the amount of air

flowing through the cooling coil, thus varying the supply air temperature to the space. As the face

and bypass damper begins to close some of the outside/return air mix is diverted around the coil

and mixed with air coming off the coil to obtain a supply air temperature that is proportional to the

reduction in space load. Because the chilled water valve remains wide open, the portion of the air

passing through the coil is dehumidified further, improving part-load dehumidification.

However, face and pass control does not actively control space humidity. It still allows the space

humidity level to rise at part-load, often higher than desired.

For more information on various methods for improving dehumidification performance of unit

ventilator systems, refer to Trane “Dehumidification in HVAC Systems” application manual

Application Considerations

Dynamic Air Barrier

In areas that contend with colder climates for a significant period of time, a school may wish to

employ a dynamic air barrier package. With this dynamic (draft) barrier system, the cold air is

captured off of the window, and drawn into the classroom unit ventilator’s normal airflow cycle.

The unit ventilator treats/warms the air as if it were part of a return-air makeup system. This

captured air is then discharged into the space providing comfort to the classroom’s occupants.

This draft barrier shield should be utilized when:

• Almost 50 percent of the wall includes windows.

• Outside air temperatures fall below 35°F for a significant period of time

• Or, in retrofit applications where the windows are of a single pane thickness.

Outdoor Air Preconditioning

Conditioning the large amounts of outdoor air required for proper classroom ventilation can

significantly increase building cooling and heating loads. It also raises the system’s first cost and

operating cost. One way to reduce the impact of the outdoor air load on the unit ventilator is to use

energy recovered from the exhaust air stream to precondition the outdoor air as it’s brought into

the building.

A total-energy recovery (enthalpy) wheel consists of a revolving cylinder filled with a desiccant-

coated medium suitable for sensible and latent (moisture) heat transfer, Figure 16, p. 20. The

Application Considerations

adjacent outdoor and exhaust air streams pass through the wheel in a counterflow arrangement

that transfers energy from one air stream to the other.

During the cooling season, the drier, sensible heat and moisture transfer from the outdoor air to

the cooler, drier exhaust air. Conversely, during the heating season, sensible heat and moisture

transfers from the exhaust air to preheat and humidify the entering outdoor air stream. Figure 16

psychrometric ally depicts the impact of a preconditioning total-energy wheel on a unit ventilator.

This approach can’t directly control humidity in the space, but it can significantly reduce the

capacity (and operating cost) of the cooling and heating equipment required to condition the

outdoor air. Capable of recovering 65 to 75 percent of the energy in the exhaust air stream, total-

energy wheels used in conjunction with unit ventilators can be an attractive alternative when

upgrading existing classroom to meet ASHRAE’s ventilation requirements; they reduce, perhaps

even eliminate, the extra capacity needed at the chiller plant or boiler.

The Trane ERS energy recovery unit ventilator is one example of a “cold coil” unit with outdoor

air preconditioning.

Note: Both preconditioning (energy recovery) and post conditioning (reheat) may be applied in

the same system.

For more information on outdoor-air preconditioning and energy recovery, refer to the Trane

application engineering manual, Air-to-Air Energy Recovery in HVAC Systems (SYS-APM003-EN).

Selection Procedure

Trane vertical classroom unit ventilators provide air delivery and capacities necessary to meet the

requirements of modern school classrooms. They are available with the industry’s widest selection

of coils to precisely satisfy heating, ventilating and air conditioning loads with the best individual

type of system. Unit ventilator selection involves three basic steps.

• Determine the classroom/space unit cooling and/or heating loads

• Determine the unit size

• Select the coil

Capacity Required

The first step in unit ventilator selection is to determine room heating and air conditioning loads.

The calculation of this load is essential if the equipment is to be economical in first cost and

operating cost.

Adequate ventilation is mandatory in classroom air conditioning design. The amount is often

specified by local or state codes and, in air conditioned schools, may be either the same or less than

that specified for heating systems. The usual requirement is between 15 and 25 cfm of outside air

per occupant, based on the intended use of the room. For instance, a chemistry laboratory normally

requires more ventilation for odor control than a low occupancy speech clinic.

Ventilation is an important concern and should be accurately determined to assure good indoor air

quality. Purposely oversizing units should be avoided, since it can cause comfort and control

issues.

Unit Size

Unit ventilator size is determined by three factors:

• Total air circulation

• Ventilation cooling economizer capacity required

• Total cooling or heating capacity required

Total air circulation, if not specified by code, should be sufficient to ensure comfort conditions

throughout the room. This is usually from six to nine air changes per hour, but can vary with room

design and exposure. Often rooms with large sun exposure require additional circulation to avoid

hot spots.

Ventilation cooling capacity is determined by the amount of outside air delivered with the outside

air damper fully open, and the temperature difference between the outside air and the classroom.

In air conditioning applications, ventilation cooling capacities should maintain the comfort setting

in the classroom whenever the outside air temperature is below the unit or system changeover

temperature.

UV-PRC003-EN.book Page 21 Tuesday, June 4, 2013 8:59 PM

22 UV-PRC003-EN

Selection Procedure

Example:

Ventilation cooling capacity = 1.085 x cfmt x (T1 - T2)

cfmt = Total air capacity of unit with outside air damper open 100 percent.

T1 = Room temperature.

T2 = Outside air temperature.

In classrooms with exceptionally heavy air conditioning loads, unit size may be determined by the

total cooling requirement. Good practice dictates 375 to 425 cfm per ton of hydronic cooling

capacity. Normally, however, Trane classroom air conditioner coils have sufficient capacities.

Example:

Given: Air circulation specified = 8 air changes per hour.

Classroom size = 35 ft long x 25 ft wide x 10 ft high

Inside design air temperature = 75 degrees F

Ventilation cooling required at 58 degrees F = 29,000 BTU

Checking ventilation cooling capacity:

29,800 BTU = 1.085 x CFM x (80-58)

CFM = 1250

This indicates that a 1250 cfm unit would have satisfactory ventilation cooling capacity at the

design changeover point of 58°F. Coil capacity will become confirmed when the coil is selected.

Coil Selection

Selecting the correct coil is done through Trane’s Official Product Selection System (TOPSS) For

your convenience, TOPSS has a mixed air calculator built into the program.

CFM required =

8 changes/hr x (35 x 25 x 10)ft3

= 1170 cfm

Why Trane Controls?

Whether involved in a retrofit or in new construction applications, Trane has the control design to

fit the systems requirements. The broad range of control packages offer a range from a field

convertible end-device package, to a complete building automation system solution with LonTalk®

controls.

The good news is Trane® controls are factory-mounted, -wired, -tested and configured or

programmed with Trane® application expertise to provide comfort, efficiency, and reliability, as

well as, single-source warranty and service. With Trane’s integrated controls, the installed costs are

lower because the equipment has turn-key factory controls and every component of the system is

optimized to fit with the controller. Trane installs not only the controller, but also the hardware that

works intimately with the controller to allow the system to function properly (i.e., piping package,

valves, dampers, actuators, etc.). When a classroom unit ventilator with Trane® controls arrives to

the jobsite, it is completely ready for quick installation.

ECM Engine Controller

The Electronically Commutated Motor (ECM) engine controls and reports the performance of up

to two Trane Brushless DC (BLDC) motors.

• The engine also coordinates the operation of the fan in response to electric heat behavior and

electric behavior in response to hydronic heat behavior.

• The engine incorporates a user interface that allows adjustment of certain unit parameters and

provides constant feedback on motor operation.

• The engine integrates service and troubleshooting tools.

• The engine integrates a versatile configurable auxiliary temperature sensor.

• The engine incorporates various safety and lockout features, such as maintaining proper fan

speeds if electric heat is called for.

Status Display

The ECM engine board contains a four-digit, seven-segment display that is used to present

information in a format close to real-world language, while having a small-form factor. Most

Customer Supplied Terminal Interface (CSTI)

The control interface is intended to be used with a field-supplied, low-voltage thermostat or

controller. The control box contains a relay board which includes a line voltage to 24-volt

transformer, quiet contactors (for electric heat units), and an optional disconnect switch. All end

devices are wired to a low-voltage terminal block and are run-tested, so the only a power

connection and thermostat connection is needed to commission the unit. Changeover sensors and

controls are provided whenever a change-over coil is selected. When N.O. valves are selected,

inverting relays are provided for use with standard thermostats.

The CSTI adapter board provides all the hookups of the standard adapter board, but in addition,

provides hookups for valve control (main and auxiliary coils), electric heat control, and damper

control. Screw terminal blocks provide convenient access to fan controls and to end device control.

In addition, a courtesy 10-Vdc supply is provided for use with an external potentiometer or rheostat.

The 10-Vdc supply supports up to 10 mA draw.

Tracer ZN520 Zone Controller

Features Include

• Automatic fan-speed reset

• Automatic ventilation reset

• Active dehumidification

• Manual output test

• Filter maintenance

• Master slave

• Water valve override

• Freeze avoidance

• Interoperability

• Three generic I/O ports

The Tracer ZN520 is a factory-installed, -tested and -commissioned LonTalk® control board

designed to provide control of the classroom unit ventilator and the fan-coil products (see

Figure 26).

The Tracer ZN520 controller is designed to be used in the following applications:

• As part of the Trane Tracer Summit building automation system, the Tracer ZN520 becomes an

important part of the Trane Integrated Comfort system (ICS).

• The Tracer ZN520 can function as a completely standalone controller in situations where a

building automation system (BAS) is not present.

• For situations when a non-Trane BAS is present, the Tracer ZN520 can be where ever a LonTalk

front-end system is present.

Through building management of the HVAC system, optimizing energy consumption becomes

possible at a classroom level. Each unit is capable of functioning independently of one another

during occupied and unoccupied hours of the day. This allows the temperature setpoint and

ventilation setting to be changed automatically based on classroom usage (see Figure 27, p. 70).

Two Systems in One

In an ICS environment, the Tracer ZN520 is pre-designed to install quickly and easily into the

system. Since the controller and the unit are factory tested and commissioned, the start-up time

for the entire system is minimized. Trane becomes the single source of responsibility for the

equipment, unit controls, and building automation system.

As a standalone controller, the Tracer ZN520 is ideally suited for fix-on-fail replacement of units

with old pneumatic controllers, or in situations where a BAS will be added at a later date. Once

power is applied to the controller, it will automatically start up and run based upon the setpoint on

the local zone sensor. An individual time clock can be added to the unit for local scheduling.

The Tracer ZN520 is certified to the interoperable LONMARK® Space Comfort Controller profile. This

allows the controller to be used with another vendor’s BAS and thereby still provide the high quality

of factory installation and testing. In addition, the Tracer ZN520 provides one of the most extensive

interoperable data lists of any controller of its type in the industry.

Tracer ZN520 Features Include

Automatic Fan and Ventilation Reset. With the Tracer ZN520 controller, a multi-speed fan

control for the unit ventilator delivers the airflow output customized to support the cfm space

needs. When less cfm is necessary to meet the load of the classroom (typically 75 to 80 percent of

the time), the equipment operates on low speed. However, if the room temperature rises, the

controller will switch to high speed, and the outside air damper will adjust to satisfy the space

needs. This helps maintain the proper amount of ventilation air to the occupants independent of

the fan speed. As part of the ventilation strategy, the controller will reposition the outside air

damper to confirm the minimum outside air cfm is met at both operating conditions.

Manual Output Test . The Tracer ZN520 controller includes a manual output test function. This

function may be initiated from the blue test push button on the controller or through the Rover™

service tool. This feature is used to manually exercise the outputs in a defined sequence.

The purpose of this test sequence is to verify output and end device operation. The manual output

test function may also be used in the following situations:

• Reset latching diagnostics

• Verify output wiring and operation

Controls

• Force the water valve(s) open to balance the hydronic system during installation set-up or

service.

Filter Maintenance. Filter status for the controller is based on the cumulative run hours of the

unit fan. The controller compares the amount of fan run time against an adjustable fan run hour

(stored in the controller) to determine when maintenance is recommended for the unit. The run-

hours value may be user edited as required (through Rover). The valid range for the fan run hours

limit is 0 to 5000 hours with a default of 600 hours. Once the run hours limit has been exceeded,

the controller generates a maintenance required diagnostic (unit will not shut-down). The user will

be notified of this diagnostic through the building automation system or when a Trane Service Tool

is communicating with the controller.

Active Dehumidification. On unit ventilators with reheat coils, the Tracer ZN520 can provide

active dehumidification to the classroom. This means that the classroom relative humidity can be

kept below an adjustable setpoint independent outdoor weather conditions. Indoor humidity levels

are recommended by ASHRAE to be kept below 60 percent in order to minimize microbial growth

and the life span of airborne illness causing germs.

Master Slave (Data Sharing). Because the Tracer ZN520 controller utilizes LONWORKS®

technology, the controller can send or receive data (setpoint, heat/cool mode, fan request, space

temperature, etc.) to and from other controllers on the communication link with or without the

existence of a building automation system. This applies to applications where multiple units might

share one zone sensor for both stand-alone (with communication wiring between units) and a

building automation system.

Water Valve Override. The Tracer ZN520 can be commanded via the Rover service tool to open

all hydronic valves 100 percent. This allows for the faster water balancing of each unit and the entire

system when the command is sent globally to all controllers. A properly balanced system is

essential for proper and efficient operation.

Hydronic Coil Freeze Protection (Freeze Avoidance). Unit ventilator systems in cold

climates need to take precautions to avoid hydronic coil freeze-up. The Tracer ZN520 does this from

three different aspects. Any of these methods of protections will result in the unit fan being

disabled, the outside air damper being shut, and the hydronic valves being opened 100 percent.

The three methods of freeze avoidance include:

1. A binary freeze protection thermostat is mounted on the coil and will cause a latching diagnostic

if the coil temperature falls below 35°F.

2. An analog discharge air sensor monitors the temperature of the air coming off of the coil and

if the temperature falls below 40°F the outside air damper is closed, the fan is turned off and

the valves are fully opened.

3. When in the unoccupied mode the Tracer ZN520 has an adjustable freeze avoidance setpoint.

If the outside air temperature is below the setpoint the unit will open the valves to allow water

to flow through the coils.

Interoperability. Interoperability allows the owner freedom to select multiple vendors, and

multiple products. With this advantage, the owner can choose the best products, the best

application, and the best service from a variety of suppliers to meet their evolving building control

needs in a cost effective manner.

Generic Binary Input/Output. The three generic binary inputs/outputs are not part of the

normal control, but are actually controlled through the Tracer Summit system (when present) to

issue commands to the Tracer ZN520 control to turn the generic inputs/outputs of add-on

equipment (such as baseboard heating, exhaust fans, occupancy sensor, lighting, etc.) on and off.

This binary port is not affected when other binary diagnostics interrupt unit operation.

Tracer UC400

The Tracer UC400 controller delivers single zone VAV control and can be used in a stand-alone

application or as part of a Trane Integrated Comfort System (ICS).

In the stand-alone configuration, Tracer UC400 receives operation commands from the zone sensor

and/or the auto changeover sensor (on auto changeover units). The entering water temperature is

read from the auto changeover sensor and determines if the unit is capable of cooling or heating.

The zone sensor module is capable of transmitting the following information to the controller:

• Timed override on/cancel request

• Zone setpoint

• Current zone temperature

• Fan mode selection (off-auto-high-med-low)

For optimal system performance, unit ventilators can operate as part of an Integrated Comfort

System (ICS) building automation system controlled by Tracer Summit. The controller is linked

directly to the Summit control panel via a twisted pair communication wire, requiring no additional

interface device (i.e., a command unit). The Trane ICS system can monitor or override Tracer UC400

control points. This includes such points as temperature and output positions.

Tracer UC400 Zone Controller Features Include

• Single Zone VAV

• Automatic ventilation reset

• Active dehumidification

• Filter maintenance

• Water valve override

• Freeze avoidance

• Interoperability

• Unused I/O can be as generic I/O

The Tracer UC400 is a factory-installed, -tested, and -commissioned BACnet® MS/TP control

designed to provide control of the classroom unit ventilator (see Figure 28). The Tracer UC400

controller is designed to be used in the following applications: as stand-alone operation, part of the

Trane Tracer SC building automation system, or part of another BACnet MS/TP Building

a later date. Once power is applied to the controller, it will automatically start up and run based

upon the setpoint on the local zone sensor. An individual time clock can be added to the unit for
