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.

Quality And Reliability Testing
• All Precedent
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.
™
designs were rigorously
• We perform a 100% coil leak test at the
factory. The evaporator and condenser
coils are leak tested at 1375 kPa (200
psig) and pressure tested to 3100 kPa
(450 psig).
• All parts are inspected at the point of
final assembly. Sub-standard parts are
identified and rejected immediately.
• The requirement for cycle testing of
heat exchangers is 10,000 cycles by
ANSI Z21.47. This is the standard
required by both UL and AGA for cycle
test requirments. Trane requires the
design to be tested to 2½ times this
current standard.
• Every unit receives a 100% unit run test
before leaving the production line to
make sure it lives up to rigorous Trane
requirements.
We test designs at our factory not on
our customers!

a gross cooling capacity of 17.8 kW and
14.4 kW sensible capacity at 35 DB
ambient and 3400 m3/h with 27 DB/ 19
WB air entering the evaporator.
Use the following formula to calculate
fan motor heat, which can be found in
the notes in Table PD-8:
Fan motor heat (kW)
= 1.144 x (Fan kW) + 0.132
For example: With 3400 m
specified by the engineer, Table PD-8
shows 0.73 kW for a high heat model.
