OptiSet Plus
OptiSet Plus is a group of programmable functions that control
how the unit will operate with specific setpoints or named
products. This assures that when a particular setpoint or named
product is selected, the unit will always operate the same way.
This allows an entire fleet to be configured to match the
customers’ needs. Contact your Thermo King dealer for
information about programming OptiSet Plus.
FreshSet
FreshSet is included in OptiSet Plus. FreshSet is a demand
base temperature control for fresh products. FreshSet modifies
and adjusts unit airflow operation to control temperature and to
maximize protection of cargo, while keeping operating costs to
a minimum. Contact your Thermo King dealer for information
about programming FreshSet.
ECO Pulldown Mode
This programmable feature allows the unit to operate in low
speed during initial pulldown until the temperature in any one
zone inside the trailer reaches 30F. At this point, it
automatically switches the unit to high speed operation. For set
points above 30F, the unit will operate in ECO Pulldown mode
until set point is achieved, possibly never operating in high
speed mode.
Operating the unit in low speed pulldown can save up to 15%
fuel during the initial pulldown without significantly
increasing the overall unit run time.
All Thermo King Multi-Temperature units come factory set
with the ECO Pulldown Mode enabled. Contact your Thermo
King dealer for further information about ECO Pulldown
Mode.
Defrost
Frost gradually builds-up on evaporator coils as a result of
normal operation. The unit uses hot refrigerant to defrost the
evaporator coil. Hot refrigerant gas passes through the
evaporator coil and melts the frost. The water flows through
collection drain tubes onto the ground. The methods of defrost
initiation are Automatic, and Manual.
Automatic Defrost:
The SR-4 MT automatically initiates
timed or demand defrost cycles. The SR-4 MT microprocessor
can be programmed to initiate timed defrost cycles at intervals
of 2, 4, 6, 8, or 12 hours. Demand defrost cycles occur if the
