OFF
OFF = Supply air temperature will be limited to the colder temperature
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 Section 4.7.1 for complete information on Perishable Sensit-
ive Product and Supply Air Configuration interaction.
TEMP
CONTROL
RETURN AIR
SUPPLY AIR
The evaporator has both a Return Air Sensor and a Supply Air Sensor.
RETURN AIR = only the return air sensor reading will be used for cal-
culating control actions. “Return Air” is generally selected for most
products.
SUPPLY AIR = the microprocessor will switch to the supply air sensor
when operating with a perishable set point (10.4°F [-12°C] or above).
“Supply Air” will control within a narrower temperature band.

FAHRENHEIT
CELCIUS
The compartment temperature will display in either English (°F) using
a decimal point to display tenths of a degree OR or Metric (°C ) using
a comma to display tenths of a degree.
NOTE: Temperature setting values displayed in the MessageCenter
will continue to use a decimal for both °F and °C.

PSIG
BAR
Pressures will display in either English (psig) or Metric (bar).
ECO MODE NO
YES
NO = When in Continuous Operation, control for maximum temperat-
ure protection.
YES = When in Continuous Operation, control for maximum fuel eco-
nomy.
RESET PM
HOUR-
METERS
This Functional Parameter allows resetting of the PM maintenance
alarm when an hour meter has timed out, or when over 95% of the
time out value has expired. If a maintenance interval has not been
configured for the alarm, this parameter will not display.
Selecting RESET and pressing the = key will de-activate the alarm,
and reset the hour meter for the next maintenance interval. The
amount of time added back into the meter before the next alarm trig-
ger is determined by the maintenance interval entered in the meter
Configuration.
If there are active maintenance hour meters and none have expired
and turned the alarm on, or none are within 95% of the time out value,
the MessageCenter will display “NO METERS TO RESET.”
NOTE: If a reset is required for a meter that has not timed out, the
meter must be configured with a “0” reset value (to turn it off) and then
reconfigured with the desired reset interval. Refer to Section 5 for
Configuration instructions.

The value entered here is the number of degrees away from set point
the compartment temperature may drift before the compartment is
considered “Out Of Range” and the configured alarm or alarm and
shutdown action will be activated. Refer to Alarm A53 - “BOX TEM-
PERATURE OUT OF RANGE” (Section 7) for more information.
