Features and

Benefits

Precedent with ReliaTel reduces the

number of components required to

operate the unit, thereby reducing

possibilities for component failure.

Some zone sensor options have central

control panel lights which indicate the

mode the unit is in and possible

diagnostic information (dirty filters for

example).

Easy to Install, Service and

Maintain

Because today’s owners are very cost-

conscious when it comes to service and

maintenance, theTrane Precedent was

designed with direct input from service

contractors.This valuable information

helped to design a product that would get

the serviceman off the job quicker and

save the owner money. Precedent does

this by offering:

ReliaTel Makes Installing and

Servicing Easy

Other ReliaTel Benefits

ReliaTel eliminates the need for field

installed anti-shortcycle timer and time

delay relays. ReliaTel controls provide

these functions as an integral part of the

unit.The contractor no longer has to

purchase these controls as options and

pay to install them.

The ReliaTel built-in anti-shortcycle timer,

time delay relay and minimum “on” time

control functions are factory tested to

assure proper operation.

ReliaTel softens electrical “spikes” by

staging on fans, compressors and

heaters.

Quality and Reliability

ReliaTel™ Controls (LCI-R)

The wiring of the low voltage connections

to the unit and the zone sensors is as

easy as 1-1, 2-2, and 3-3.This simplified

system makes wiring easier for the

installer.

Intelligent Fallback is a benefit to the

building occupant. If a component goes

astray, the unit will continue to operate at

predetermined temperature setpoint.

Intelligent Anticipation is a standard

ReliaTel feature. It functions continuously

as ReliaTel and zone sensor(s) work

together in harmony to provide much

tighter comfort control than conventional

electro-mechanical thermostats.

ReliaTel MakesTesting Easy

ReliaTel requires no special tools to run

the Precedent unit through its paces.

Simply place a jumper betweenTest 1

andTest 2 terminals on the LowVoltage

Terminal Board and the unit will walk

through its operational steps

automatically.

The same ReliaTel Board fits all

Precedent Packaged Gas/Electrics,

Cooling with Electric Heat, and Heat

Pump models.This provides

standardization of parts for contractors.

Less money is tied up in inventory with

ReliaTel.

ReliaTel controls provide unit control for

heating, cooling and ventilating utilizing

input from sensors that measure outdoor

and indoor temperature.

—The unit automatically returns

control to the zone sensor after

stepping through the test mode a

single time, even if the jumper is

left on the unit.

Quality and Reliability are enhanced

through ReliaTel control and logic:

As long as the unit has power and the

“system on” LED is lit, ReliaTel is

operational.The light indicates that the

controls are functioning properly.

—prevents the unit from short cycling,

considerably improving

compressor life.

—ensures that the compressor will run

for a specific amount of time which

allows oil to return for better

lubrication, enhancing the reliability of

the compressor.

ReliaTel features expanded diagnostic

capabilities when utilized withTrane

Integrated Comfort™ Systems.

Features and

Benefits

Compressors

Digital Display Zone Sensor

Outstanding Standard and

Optional Components

Precedent contains the best compressor

technology available to achieve the

highest possible performance. Our

compressor line includes reciprocating

and scrolls.

The Digital LCD (Liquid Crystal Display)

zone sensor has the look and functionality

of standard zone sensors. This sensor

should be utilized with ReliaTel™ controls.

Black Epoxy Pre-Coated Coils

The pre-coated coils are an economical

option for protection in mildly corrosive

environments.

Discharge Air Sensing Kit

Provides true discharge air sensing in

heating models. The kit is functional only

with the ReliaTel Options Module.

Cabinet Integrity

For added water integrity, Precedent has

a raised 1¹/₈" lip around the supply and

return of the downflow units to prevent

water from blowing into the ductwork.

DownflowAnd Horizontal Economizers

The economizers come with three control

options — dry bulb is standard, enthalpy

and differential enthalpy are optional.

Clogged Filter/Fan Failure Switch

A dedicated differential pressure switch is

available to achieve active fan failure

indication and/or clogged filter indication.

DualThermistor Remote Zone Sensor

This sensor will reduce the total number

of remote sensors to obtain space

temperature averaging. This sensor

should be utilized with ReliaTel controls.

These sensors allow a zone sensor

service light or Integrated Comfort

System to indicate a dirty filter or a fan

that’s not working.The field installation

charges for these valuable feedback

devices often eliminate them from

consideration. Factory installation can

make such features a good investment.

Condenser Coil

Precedent boasts a patent-pending

1+1+1 condenser coil, permanently

gapped for easy cleaning.

Foil-Faced Insulation

All panels in the evaporator section of the

unit have cleanable foil-faced insulation.

All edges are either captured or sealed to

ensure no fibers get into the airstream.

Factory Built Roof Curbs

Only two roof curbs for the entire

Precedent line simplifies curb selection.

CO₂Sensing

The CO₂sensor has the ability to monitor

space occupancy levels within the

building by measuring the parts per

million of CO₂(Carbon Dioxide) in the air.

As the CO₂levels increase, the outside air

damper modulates to meet the CO₂

space ventilation requirements.The CO

sensor kit is available as a field installed²

accessory.

Flexibility

Units are built to order in our standard

“shortest in the industry” ship cycle time.

Fresh Air

0 - 25% manual or 0 - 50% motorized

outside air hoods are available.

Application

Considerations

Application of this product should be

within the cataloged airflow and cooling

considerations.

Condensate Trap

The evaporator is a draw-thru

configuration. A trap must be field

provided prior to start-up on the cooling

cycle.

LowAmbient Cooling

The Precedent™ line features, with

ReliaTel™ microprocessor controls, low

ambient cooling down to 0°F.

Clearance Requirements

The recommended clearances identified

with unit dimensions should be

maintained to assure adequate service

maximum capacity and peak operating

efficiency. Actual clearances which

appear inadequate should be reviewed

with the localTrane sales personnel.

Barometric Relief

This product line offers an optional

barometric relief damper. for use in

conjunction with economizer option. This

accessory consists of gravity dampers

which open with increased pressure. As

the building air pressure increases, the

pressure in the unit return air section

also increases, opening the dampers and

relieving the conditioned space.

Unit Pitch

These units have reversible sloped

condensate drain pans. Units must be

installed level, any unit slope must be

toward the side of unit where condensate

drain is connected.

Selection

Procedures

Step 4

Cooling Capacity

Step 1

Calculate the building’s total and sensible

cooling loads at design conditions. Use

theTrane calculation methods or any

other standard accepted method.

Heating Capacity

Step 1

Calculate the building heating load using

theTrane calculation form or other

standard accepted method.

In order to select the correct unit which

meets the building’s requirements, the

fan motor heat must be deducted from

the gross cooling capacity.The amount of

heat that the fan motor generates is

dependent on the effort by the motor -

cfm and static pressure.To determine the

total unit static pressure:

Step 2

Size the equipment usingTable PD-31 to

Factors used in unit selection:

Because 32.7 is less than the building’s

required heating capacity at winter

design conditions, a supplementary

heater must be selected.

Economizer

Note:The Evaporator Fan Performance

Table PD-12 has deducted the pressure

drop for a 1 in. filter already in the unit

(see note belowTable PD-12).Therefore,

the actual total static pressure is 0.69 -

0.09 (fromTable PD-23) = 0.60 wg.

Step 2

As a starting point, a rough determination

must be made of the size of the unit.The

final selection will be made after

examining the performance at the given

conditions. Divide the total cooling load by

nominal BTUH per ton (12 MBh per ton);

then round up to the nearest unit size.

50 MBh-32.7 MBh = 17.3 MBh

The auxiliary eletric heat capacities are

listed inTable PD-38. From the table, a 6

kW heater will deliver 20.48 MBH at 480

volts. In order to determine capacity at

460 volts, the heater voltage correction

factor fromTable PD-39 must be used.

Therefore, 20.48 MBH x .918 (voltage

correction factor) = 18.80 MBH. A 6kW

heater should be selected.

With 2000 cfm and 0.60 wg.

Table PD-46 shows .90 bhp for this unit.

Note below the table gives a formula to

calculate Fan Motor Heat,

59 MBh / 12 MBh = approx. 5 tons

2.829 x bhp + .4024 = MBH.

2.829 x .90 + .4024 = 2.95 MBH.

Step 3

Table PD-3 shows that a WSC060A4 has

a gross cooling capacity of 63.1 MBh and

47.5 MBh sensible capacity at 2000 cfm

and 95 DB outdoor ambient with 80 DB,

67 WB air entering the evaporator.

Now subtract the fan motor heat from

the gross cooling capacity of the unit:

NetTotal Cooling Capacity

Air Delivery Selection

External static pressure drop through

the air distribution system has been

calculated to be 0.60 inches of water.

EnterTable PD-12 for a WSC060A4 at

2000 cfm and 0.60 static pressure.The

belt drive motor will give the desired

airflow at a rated bhp of 0.90 and 998

rpm.

= 63.1 MBH - 2.95 = 60.15 MBH.

Net Sensible Cooling Capacity

= 47.5 MBH - 2.95 = 44.55 MBH.

To Find Capacity at Intermediate

Conditions Not in theTable

Step 5

When the design conditions are between

two numbers that are in the capacity

table, interpolation is required to

approximate the capacity. Note:

Extrapolation outside of the table

conditions is not recommended.

Compare results to original load

requirements.

If the performance will not meet the

building’s required total or sensible

cooling load, try a selection at the next

higher size unit.

Fanmotorheat(MBh)=4.39xFanBhp

Factory supplied motors, in commercial equipment, are definite purpose motors, specifically designed and tested to operate reliably and continuously at all

cataloged conditions. Using the full horsepower range of our fan motors as shown in our tabular data will not result in nuisance tripping or premature motor

failure. Our product’s warranty will not be affected.

Notes:

1. Data includes pressure drop due to wet coil and filters.

2. 5 ton oversized motor performance is with 12 x 11 FC blower wheel.
