AUTOFRESH AIR
CLOSED
OPEN
CFM CONTROL
Closed = AutoFresh Air Exchange assembly will be closed.
Open = Assembly will be open if the engine is running and the
setpoint is greater than 28.0°F (-2.22°C).
CFM Control = Assembly will be cycled open and closed over
a 20 minute time period. The length of time the assembly is
opened or closed is based on the Auto Fresh Air Control Func-
tional Parameter. The CFM CONTROL will only be active if the
engine is running and the setpoint is greater than 28.0°F (-
2.22°C).
AUTOFRESH AIR
CONTROL
5 To 50 CFM (in 5 CFM in-
crements)
25 CFM
When CFM Control is selected, this setting is used to set the
amount of air to be exchanged during each 20 minute cycle.
PERISH SENSITIVE
PRODUCT
ON
OFF
OFF = Supply air temperature will be limited to the colder tem-
perature of 32°F (0°C) or set point less the SUPPLY AIR LIMIT
CONFIGURATION VALUE.
ON = Supply air temperature will be limited to set point less the
Supply air Limit Configuration value.
Refer to
for information on Perishable Sensi-
tive Product and Supply Air Configuration interaction.
START-STOP SETTINGS
Time and Temperature values that control Start-Stop Operation are set in this section. The system may be config-
ured so that:
1. the same settings apply to any setpoint = “Together”
or
2. the settings are different, depending on whether the setpoint is in the perishable range or in the frozen
range = “Separate”.
• If “together” is configured, there will be six settings with only the sixth applicable to just frozen range.
• If “Separate” is configured there will be eleven settings five labeled perishable and six labeled frozen.
MIN RUN TIME:
4MINS
TO
60MINS (in 1 minute in-
crements)
This determines the minimum run time for perishable/frozen
setpoints in Start-Stop Operation
MIN OFF TIME:
10 to 90MINS (in 1 minute
increments)
30 MINS
This determines the minimum off time for perishable/frozen
setpoints in Start-Stop Operation.
RESTART TEMP:
0.5 to 18°F (.28 to 10°C)
(in 0.5° increments)
5.5°F (3°C)
Following the Minimum Off Time, should a compartment tem-
perature drift this far above or below setpoint in the Perishable
Range or above setpoint in the Frozen Range, the unit will re-
start.
OVERRIDE TEMP:
3.6 to 18°F (2 to 10°C) (in
0.5 degree increments)
12.0°F (6.7°C)
This selects the override temperature for the Minimum Off
Time portion of the Auto Start-Stop Off Cycle. During the Min-
imum Off Time, should the refrigerated compartment tempera-
ture drift this far above or below setpoint in the Perishable
Range, or above setpoint in the Frozen Range, the unit will
override the Minimum Off Time, and restart.
