Micro Controls
Several years ago, Trane was the first to
introduce microprocessor controls into
the Light Commercial Market. That
design, along with immeasurable
experience, has provided the technology
for Trane’s second-generation ReliaTel™
microprocessor controls.
ReliaTel™ Micro:
• Provides unit control for heating,
cooling, and ventilating by utilizing input
from sensors that measure outdoor
and indoor temperature.
• Improves quality and reliability through
the use of time-tested microprocessor
controls 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.
• Reduces the number of components
required to operate the unit, thereby
reducing possibilities for component
failure.
• Eliminates the need for field-installed
components with its built-in anti-shortcycle timer, time delay relay and
minimum ‘’on’’ time controls. These
controls are factory tested to assure
proper operation.
• Requires no special tools to run the
Precedent unit through its paces during
testing. 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. 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
LED is lit, the Micro is operational. The
light indicates that the Micro is
functioning properly.
• Features expanded diagnostic
capabilities when used with Trane’s
Integrated Comfort
• As an energy benefit, softens electrical
‘’spikes’’ by staging on fans,
compressors and heaters.
• The Intelligent Fallback or Adaptive
Control is a benefit to the building
occupant. If a component goes astray,
the unit will continue to operate at
predetermined temperature set points.
• Intelligent Anticipation is a standard
feature of the Micro. Functioning
constantly, the Micro and zone sensors
work together in harmony, to provide
tight comfort control.

Features and
Benefits
Factory-installed Options
Economizer
Equipped with either dry bulb, reference
or comparative enthalpy sensing, this
feature provides free cooling as the
outdoor temperature and/or humidity
decreases. Economizers, correctly
installed, offer a valuable energy
savings. Factory-installed economizers
save time and ensure proper installation.
Trane Communication Interface
Available factory or field-installed. This
module when applied with ReliaTel™
easily interfaces with Trane’s Integrated
Comfort
Hinged Access Doors
These doors permit easy access to the
filter, fan/heat, and compressor/control
sections. They reduce the potential roof
damage from screws or sharp access
door corners.
Through the Base Electrical Utility
Access
Factory provided through the base
openings simplify wiring and piping.
Because these utility openings
frequently minimize the number of roof
penetrations, the integrity of roofing
materials is enhanced.
Unit Mounted Disconnect or Circuit
Breaker
Codes require a method of assured unit
shutdown for servicing. Field-installed
disconnects sometimes interfere with
service access. Factory installation of unit
disconnects reduces costs, assures
proper mounting and provides the
opportunity to upgrade to unit circuit
breaker protection.
Clogged Filter/Fan Fail Switches
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.

Features and
Benefits
Quality And Reliability Testing
• All Precedent™ 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

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 0F. With
electromechanical controls, Precedent
features low ambient cooling to 40F.
Contact your local Trane Representative
for more assistance with low ambient
cooling 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.
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.
Condensate Trap
The evaporator is a draw-thru
configuration. A trap must be field
provided prior to start-up on the cooling
cycle.

RT-PRC005-EN
Selection
Procedure
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.
60 MBh / 12 MBh = 5 Tons
Step 3
Table PD-4 shows that a TSC060A4 has a
gross cooling capacity of 63.1 MBh and
48.2 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)
0.45 wg
Standard Filter 1 in.0.15 wg
from Table PD-59
Economizer0.02 wg
(100% Return Air) from Table PD-26
Electric Heater Size 6 kW0.05 wg
from Table PD-51
Total Static Pressure0.67 wg
Note: The Evaporator Fan Performance
Table PD-20 has deducted the pressure
drop for a 1 in. filter already in the unit
(see note below Table PD-20). Therefore,
the actual total static pressure is 0.67 -
0.15 (from Table PD - 26) = 0.52 wg.
With 2000 cfm and 0.52 wg.
Table PD-20 shows .90 bhp for this unit.
Note below the table gives a formula to
calculate Fan Motor Heat,
4.39 x bhp = MBH.
4.39 x .90 = 3.95 MBH.
Now subtract the fan motor heat from
the gross cooling capacity of the unit:
Net Total Cooling Capacity
= 60 MBH - 3.95 = 56.05 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.
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 15 MBH
B
2000 cfm
C
460 volt/3 phase Power Supply
The electric heat accessory capacities
are listed in Table PD-62 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-60 must
be used. Therefore, 20.48 MBH x .9118
(voltage correction factor) = 18.80 MBH.
Air Delivery Selection
External static pressure drop through
the air distribution system has been
calculated to be 0.45 inches of water.
From Table PD-59 static pressure drop
through the economizer is 0.02 and the
6 kW heater is 0.05 inches of water (0.45
+ 0.02 + 0.05). Enter Table PD-20 for a
TSC060A4 at 2000 cfm and 0.52 static
pressure. The standard direct drive
motor at high speed will give the
desired airflow at a rated bhp of 0.90.
