ECONOMY SETTINGS
LOW SPEED
DELAY S/S:
0 MINS TO 255MINS (in
1 minute increments)
10 MIN
Select the length of time the unit is to remain in low speed af-
ter starting, before transitioning to high speed, when in Start-
Stop Operation.
LOW SPEED
DELAY CONT:
0 MINS TO 255MINS (in
1 minute increments)
0 MIN
Select the length of time the unit is to remain in low speed af-
ter starting, before transitioning to high speed, when in Con-
tinuous Operation.
AIR FLOW NORMAL
HIGH
NORMAL = allows the unit to cycle from High Speed to Low
Speed, based on compartment temperature.
HIGH = Some products generate a considerable amount of
heat (heat of respiration) during transportation. This frequent-
ly occurs with produce. The HIGH selection is used for these
loads, if continuous high air flow is required to keep the entire
load at a constant temperature. The engine will remain in High
Speed when High is selected.
NOTE: HIGH AIR FLOW is not active with setpoints below
+10.4°F (-12.0°C).
DEFROST TIMER
SET FOR
1.5 HRS
3 HRS
6 HRS
12 HRS
The defrost timer will automatically put the unit into the defrost
cycle at the interval selected if DTT is below 40°F (4.4°C) or
the SAT is below 45°F (7.2°C).
Shorter times are generally used for warm, humid products
like produce.
Longer times can be used for dry and frozen products.
NOTE: The timer increments time toward the next defrost
only when DTT is below 40°F and the unit is running.
FRESH PROTECT OFF
A, B, C, D, E
OFF = FreshProtect is turned off.
A through E each place an individual flexible limit on how far
below setpoint the supply air temperature can drop when in
Continuous Operation with a setpoint above 32°F (0°C).
Refer to Section Section 4.10.1 for more information on
FreshProtect.
