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 antishort-cycle 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.

Application Considerations
Application of this product should be
within the cataloged airflow and cooling
considerations.
Low Ambient Cooling
Precedent™ features, as standard, low
ambient cooling down to -18°C (0°F).
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 option 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 side of unit where condensate
drain is connected.

Procedure - SI Units
Cooling Capacity
Step 1
Calculate the building’s total and
sensible cooling loads at design
conditions. Use the Trane calculation
form or any other standard accepted
method.
Step 2
Size the equipment using Table PD-1.
Match the cooling loads at design
conditions.
Example: The following are the building
cooling requirements:
A
Electrical Characteristics: 380–415/50/3
B
Summer Design Conditions:
Entering Evaporator Coil: 27 DB/ 19 WB
Outdoor Ambient: 35

Table PD-1 shows that a WSC060AD has
a gross cooling capacity of 18.1 kW and
14.7 kW sensible capacity at 35 degree C
ambient and 3,400 m
WB air entering the evaporator.
To find the net cooling capacities, fan
motor heat must be subtracted.
Determine the total unit static pressure:
External Static 130 Pa
Standard Filter 1 in. 37 Pa
Economizer 46 Pa
Supplementary Electric Heat 21 Pa
Total Static Pressure 234 Pa
Note: The Evaporator Fan Performance
Table PD-9 has deducted the pressure
drop for a 25 mm filter already in the
downflow unit.
Therefore, the actual Total Static
Pressure is 234 – 37 = 197 Pa. With 3,400
m3/hr and 197 Pa, Table PD-9 shows 0.75
kW.
Note below the table gives a formula to
calculate Fan Motor Heat,
Fan Motor Heat (kW) =
1.144 x (Fan kW) + 0.132
= 1.144 x 0.75 + 0.132 = 1.0 kW
Net Total Cooling Capacity =
18.1 – 1.0 = 17.1 kW
Net Sensible Cooling Capacity =
14.7 – 1.0 = 13.7 kW

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-5 to
match the heating loads at design
conditions.
A
Total Heating Load: 16 kW
B
Outdoor Ambient (Winter) –9°C DB
C
Indoor Return Temperature: 21°C DB
D
Airflow: 3,400 m3/hr
Use the portion of Table PD-5 for the
WSC060AD to determine capacity at
winter design conditions. The
mechanical heating portion of the heat
pump will provide 8.3 kW.
Step 3
Because 8.3 kW is less than the
building’s required heating capacity at
winter design conditions, a
supplementary heater must be selected.
16 kW – 8.3 kW = 7.7 kW
From Table PD-9, at 380 volts, the 10.9
kW Heater will be adequate to do the
job.
From Table ED-5 select heater
BAYHTRR418A (10.9 kW 380/50/3).
Air Delivery Selection
External static pressure drop through the
air distribution system has been
calculated to be 200 Pa. Enter Table PD-9
for a WSC060AD at 3400 m
Pa static pressure. The standard motor
will give the desired airflow.

Cooling Capacity
Step 1
Calculate the building’s total and
sensible cooling loads at design
conditions. Use the Trane calculation
form or any other standard accepted
method.
Step 2
Size the equipment using Table PD-1a.
Match the cooling loads at design
conditions.
Example: The following are the building
cooling requirements:
A
Electrical Characteristics: 380–415/50/3
B
Summer Design Conditions:
Entering Evaporator Coil: 80 DB/ 67 WB
Outdoor Ambient: 95

Downflow Configuration
Table PD-1a shows that a WSC060AD
has a gross cooling capacity of 59.0 MBh
and 45.7 MBh sensible capacity at 95
degree ambient and 2,000 cfm with 80
DB/67 WB air entering the evaporator.
To find the net cooling capacities, fan
motor heat must be subtracted.
Determine the total unit static pressure:
External Static 0.52 in.
Standard Filter 1 in. 0.15 in.
Economizer 0.18 in.
Supplementary Electric Heat 0.083 in.
Total Static Pressure 0.933 in.
Note: The Evaporator Fan Performance
Table PD-9a has deducted the pressure
drop for a 1 in. filter already in the
downflow unit.
Therefore, the actual Total Static
Pressure is 0.933 – 0.15 = 0.78. With
2,000 cfm and 0.78 inches, Table PD-9a
shows 1.00 bhp.
Note below the table gives a formula to
calculate Fan Motor Heat,
Fan Motor Heat (MBh) =
2.915 x (Fan bhp) + 0.451
= 2.915 x 1.00 + 0.451 = 3.37 MBh
Net Total Cooling Capacity =
57 – 3.37 = 53.6 MBh
Net Sensible Cooling Capacity =
38 – 3.37 = 34.6 MBh
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-5a 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: 2,000 cfm
Use the portion of Table PD-5a for the
WSC060AD to determine capacity at
winter design conditions. The
mechanical heating portion of the heat
pump will provide 29.1 MBh.
Step 3
Because 29.1 MBh is less than the
building’s required heating capacity at
winter design conditions, a
supplementary heater must be selected.
50 MBh – 29.1 MBh = 29.9 MBh
From Table PD-9a, at 380 volts, the 38.0
MBh Heater will be adequate to do the
job.
10.9 kW 38.0 MBh
From Table ED-2 select heater
BAYHTRR418A (38.0 MBh at 380 volts).
Air Delivery Selection
External static pressure drop through the
air distribution system has been
calculated to be 0.80 inches of water.
Enter Table PD-9a for a WSC060AD at
2000 cfm and 0.80 static pressure. The
standard motor will give the desired
airflow.
