Features and
Benefits
Easy to Install, Service and
Maintain
Because today’s owners are very costconscious when it comes to service and
maintenance, the Trane 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:
Quality and Reliability
ReliaTel™ Controls (LCI-R)
ReliaTel controls provide unit control for
heating, cooling and ventilating utilizing
input from sensors that measure outdoor
and indoor temperature.
Quality and Reliability are enhanced
through ReliaTel control and logic:
—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.
Precedent with ReliaTel reduces the
number of components required to
operate the unit, thereby reducing
possibilities for component failure.
ReliaTel Makes Installing and
Servicing Easy
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 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.
ReliaTel Makes Testing Easy
ReliaTel requires no special tools to run
the Precedent unit through its paces.
Simply place a jumper between Test 1
and Test 2 terminals on the Low Voltage
Terminal Board and the unit will walk
through its operational steps
automatically.
— 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.
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.
ReliaTel features expanded diagnostic
capabilities when utilized with Trane
Integrated Comfort™ Systems.
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).
Other ReliaTel Benefits
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.
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.
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.

Black Epoxy Pre-Coated Coils
The pre-coated coils are an economical
option for protection in mildly corrosive
environments.
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.
Clogged Filter/Fan Failure Switch
A dedicated differential pressure switch is
available to achieve active fan failure
indication and/or clogged filter indication.
These sensors allow a zone sensor
service light or Integrated Comfort

Features and
Benefits
Unit Cabinet
The compact cabinet with rounded
corners takes up less room and is less
costly to ship. The beveled and ribbed top
is not only aesthetically pleasing, it is
designed to prevent water from pooling.
Va riTra c
When Trane’s changeover VAV System
for light commercial applications is
coupled with Precedent, it provides the
latest in technological advances for
comfort management systems and can
allow thermostat control in every zone
served by VariTrac.
Ventilation Override Accessory
With the Ventilation Override Accessory
installed, the unit can be set to transition
to up to 3 different pre-programmed
sequences for Smoke Purge,
Pressurization, and Exhaust. The
transition occurs when a binary input on
the RTOM is closed (shorted). This would
typically be a hard wired relay output
from a smoke detector or fire control
panel. The ventilation override kit is
available as a field installed accessory.
Zone Sensors
Available in programmable, automatic
and manual styles.
Precedent offers ultimate flexibility. Units
are built to order in our standard
“shortest in the industry” ship cycle time.
Rigorous Testing
All of Precedent’s designs were
rigorously rain tested at the factory to
ensure water integrity.
Actual shipping tests were performed to
determine packaging requirements. Units
were test shipped around the country to
determine the best packaging. Factory
shake and drop tests were used as part
of the package design process to help
assure that the unit arrives at the job site
in top condition.
Rigging tests include lifting a unit into the
air and letting it drop one foot, assuring
that the lifting lugs and rails hold up under
stress.
We perform a 100% coil leak test at the
factory. The evaporator and condenser
coils are leak tested at 200 psig and
pressure tested to 450 psig.
All parts are inspected at the point of final
assembly. Sub-standard parts are
identified and rejected immediately.
Every unit receives a 100% unit run test
before leaving the production line to
make sure it lives up to rigorous Trane
requirements.

Features and
Benefits
Easy to Install
Convertible Units
–The units ship in a downflow
configuration. They can be easily
converted to horizontal by simply
moving two panels.
– Units come complete with horizontal
duct flanges so the contractor doesn’t
have to field fabricate them. These duct
flanges are a time and cost saver.
Easy Access Low Voltage Terminal Board
Precedent’s Low Voltage Terminal Board
is external to the electrical control
cabinet. It is extremely easy to locate and
attach the thermostat wire and test
operation of all unit functions. This is
another cost and time saving installation
feature.

Application Considerations
Application of this product should be
within the cataloged airflow and cooling
considerations.
Low Ambient Cooling
The Precedent™ line features, with
ReliaTel™ microprocessor controls, low
ambient cooling down to 0°F.
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.
NOTE: THE EFFECTIVENESS OF
BAROMETRIC RELIEF DAMPER DURING
ECONOMIZING OPERATION IS SYSTEM
RELATED.
PRESSURE DROP OF THE RETURN AIR
SYSTEM SHOULD BE CONSIDERED TO
CONTROL BUILDING PRESSURIZATION.
Condensate Trap
The evaporator is a draw-thru
configuration. A trap must be field
provided prior to start-up on the cooling
cycle.
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 local Trane sales personnel.
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
Cooling Capacity
Step 1
Calculate the building’s total and sensible
cooling loads at design conditions. Use
the Trane calculation methods or any
other standard accepted method.
Factors used in unit selection:
A
Total Cooling Load: 59 MBh
B
Sensible Cooling Load: 40 MBh
C
Airflow: 2000 cfm
D
Electrical Characteristics: 460/60/3
E
Summer Design Conditions: Entering
Evaporator Coil: 80 DB, 67 WB Outdoor
Ambient: 95
F
External Static Pressure: 0.36 in. wg
G
Downflow Configuration
H
High Efficiency
I
Economizer
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.
59 MBh / 12 MBh = approx. 5 tons
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.
To Find Capacity at Intermediate
Conditions Not in the Table
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.
Step 4
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:
External Static (duct system)
0.36 wg
Standard Filter 1 in. 0.09 wg
from Table PD-23
Economizer 0.18 wg
(100% Outside Air) from Table
PD-23
Electric Heater Size 6 kW 0.056 wg
from Table PD-23
(reference “Heating Capacity” section on
this page for determination of heater
size)
Total Static Pressure 0.69 wg
Note: The Evaporator Fan Performance
Table PD-12 has deducted the pressure
drop for a 1 in. filter already in the unit
(see note below Table PD-12). Therefore,
the actual total static pressure is 0.69 -
0.09 (from Table PD-23) = 0.60 wg.
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,
2.829 x bhp + .4024 = MBH.
2.829 x .90 + .4024 = 2.95 MBH.
Now subtract the fan motor heat from
the gross cooling capacity of the unit:
Net Total Cooling Capacity
= 63.1 MBH - 2.95 = 60.15 MBH.
Net Sensible Cooling Capacity
= 47.5 MBH - 2.95 = 44.55 MBH.
Step 5
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.
Heating Capacity
Step 1
Calculate the building heating load using
the Trane calculation form or other
standard accepted method.
Step 2
Size the equipment using Table PD-31 to
match the heating loads at design
conditions.
A
Total heating load: 50 MBH
B
Outdoor Ambient (Winter) 17 DB
C
Indoor Return Temperature: 70 DB
D
Airflow: 2000cfm
Use the integrated portion of Table PD-31
for the WSC060A4 to determine
capacity at winter design conditions. The
mechanical heating portion of the heat
pump will provide 32.7 MBh.
Step 3
Because 32.7 is less than the building’s
required heating capacity at winter
design conditions, a supplementary
heater must be selected.
50 MBh-32.7 MBh = 17.3 MBh
The auxiliary eletric heat capacities are
listed in Table 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 from Table PD-39 must be used.
Therefore, 20.48 MBH x .918 (voltage
correction factor) = 18.80 MBH. A 6kW
heater should be selected.
Air Delivery Selection
External static pressure drop through
the air distribution system has been
calculated to be 0.60 inches of water.
Enter Table 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.
