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.
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.
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.
Pressures will display in either English (psig) or Metric (bar).
NO = When in Continuous Operation, control for maximum temperat-
ure protection.
YES = When in Continuous Operation, control for maximum fuel eco-
nomy.
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,
RESET
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.
RESET
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."
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
RESET
Configuration instructions.
English The value entered here is the number of degrees away from set point
OFF
the compartment temperature may drift before the compartment is
4°F
considered "Out Of Range" and the configured alarm or alarm and
5°F
shutdown action will be activated. Refer to Alarm A53 - "BOX TEM-

PERATURE OUT OF RANGE" (Section 7) for more information.
