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.
Electromechanical Controls
For the simpler job that does not require
a building automation system, or
expanded diagnostics capabilities,
Precedent offers electromechnical
controls. This 24-volt control includes the
control transformer and contactor
pressure lugs for power wiring.

Features and
Benefits
Outstanding Standard and
Optional Components
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 1
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
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.
CO2 Sensing
The CO2 sensor has the ability to monitor
space occupancy levels within the
building by measuring the parts per
million of CO
As the CO2 levels increase, the outside air
damper modulates to meet the CO
space ventilation requirements. The CO
sensor kit is available as a field installed
accessory.

VariTrac™
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.

applications.
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.
Heating Operation
The heat exchanger is manufactured
with aluminized steel. To prevent
condensation within the heat exchanger,
do not exceed 50% outside air or a
minimum mixed air temperature of 40°F.
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.
11RT-PRC006-EN
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.
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.
58 MBh / 12 MBh = approx. 5 tons
Step 4
Verify the unit will have enough capacity
to meet the building requirements by
determining the net capacity, which
includes heat generated by the fan. 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 add the external
static pressure to the additional static
created by the added features:
External Static (duct system)
0.52 wg
Standard Filter 1 in.0.06 wg
from Table PD-89
Economizer0.18 wg
(100% Outside Air)from Table
PD-89
Total Static Pressure0.76 wg
Note: The Evaporator Fan Performance
Table PD-64 has deducted the pressure
drop for a 1 in. filter already in the unit
(see note below Table PD-64). Therefore,
the actual total static pressure is 0.76 -
0.06 (from Table PD - 89) = 0.70 wg.
With 2000 cfm and 0.70 wg., Table PD-64
shows 1.07 bhp for this unit. Note below
the table gives a formula to calculate Fan
Motor Heat,
Heating Capacity
Step 1 — Calculate the building heating
load using the Trane calculation form or
other standard accepted method.
Step 2 — Size the system heating
capacity to match the calculated
building heating load. The following are
building heating requirements:
a. Total heating load of 60.0 MBh
b. 2000 cfm
c. Fuel - Natural gas
For the YSC060A4 there are three
heating capacities available, 60 MBh, 80
MBh and 130 MBh input models shown
in Table PD-91. The output capacities of
these furnaces are 48 MBh, 64 MBh
and 104 MBh respectively. The medium
heat model with 64 MBh best matches
the building requirements, indicating a
YHC060A4*M should be selected.
Air Delivery Selection
External static pressure drop through
the air distribution system has been
calculated to be 0.7 inches of water.
Enter Table PD-64 for a YHC060A4*M at
2000 cfm and 0.70 static pressure. The
standard belt drive motor will give the
desired airflow with 1.07 bhp and 1094
rpm.
Accessory Selection
Select accessories needed to
accommodate the application.
Step 3
Examine gross capacity: Table PD-13
shows that a YHC060A4 has a gross
cooling capacity of 62.4 MBh and 48.4
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.
2.829 x bhp + .4024 = MBH.
2.829 x 1.07 + .4024 = 3.43 MBH.
Now subtract the fan motor heat from
the gross cooling capacity of the unit:
Net Total Cooling Capacity
= 62.4 MBH - 3.43 = 58.97 MBH.
If the performance will not meet the
required load of the building’s total or
sensible cooling load, try a selection at
the next higher size unit.

Consider Chart C-1. If the space relative
humidity is equal to or above the space
relative humidity setpoint, the
Dehumidification option will:
• Energize compressor or both
compressors (2 stage compressor units).
• Hot gas reheat valve is energized and
hot gas is diverted to the reheat coil.
• Dehumidification/reheat is terminated
when space humidity is reduced to 5%
below relative humidity setpoint.
At MA’, air enters the RTU. The RTU filters,
cools, and dehumidifies the air as it
moves through the evaporator coil. Air
leaves the evaporator coil saturated at
the preset dew point condition (SA’) and
is reheated by the hot gas reheat coil to
deliver 76°F (SA) supply air to the space.
