Cd36 Evaporator Fan Speed This is the desired evaporator fan speed for use during the bulb Dehumidification
and Humidification Mode option.
(Replaced by Cd48 if CnF50, Enhanced Bulb Mode, is active.)
This code is enabled only if in the Dehumidification Mode (Cd33) and Bulb Mode
(Cd35) has been set to “bulb.” If these conditions are not met, “alt” will be
displayed (indicating that the evaporator fans will alternate their speed) and the
display cannot be changed.
If a dehumidification setpoint has been selected along with Bulb Mode then “alt”
may be selected for alternating speed, “Lo” for low speed evaporator fan only, or
“Hi” for high speed evaporator fan only.
If a setting other than “alt” has been selected and Bulb Mode is deactivated in any
manner, then selection reverts back to “alt.”
Cd37 Variable DTT Setting
(Bulb Mode)
This is the variable defrost termination thermostat setting to be used with the
optional Bulb Mode functionality. This item is only displayed if the Bulb Mode
option is configured on.
(Replaced by Cd48 interface if CnF50 Enhanced Bulb Mode Interface is active.)
Display Only Functions
- Cd38 through Cd40 are display only functions.
Cd38 Secondary Supply
Temperature Sensor
Cd38 will display the current supply recorder sensor (SRS) reading for units
configured for four probes. If the unit is configured with a DataCORDER, Cd38
will display “-----.” If the DataCORDER suffers a failure, Cd38 will display the
supply recorder sensor reading.
Cd39 Secondary Return
Temperature Sensor
Cd39 will display the current return recorder sensor (RRS) reading for units
configured for four probes. If the unit is configured with a DataCORDER, Cd39
will display “-----.” If the DataCORDER suffers a failure, Cd39 will display the
return recorder sensor reading.
Cd40 Container Identification
Number
If a valid container id exists, the default display for Cd40 will be “cd40_XXXXX”
where “XXXXX” is the 5th character through the 9th character of the container id.
Press the Enter key while on Cd40 to display “id_YYYYYYY” where “YYYYYYY”
is the 5th character to the 11th character of the container id.
If no valid container id exists or the container id is blank, the default display will
have Cd40 on the left display and the right display will alternate between “_nEEd”
and “___id”. Press the ENTER key while on Cd40 in this state to prompt the Set
Id Interface.
On start up if the container id is not valid, Cd40 will be brought up on the display
for the first minute of power up. This can be left by either entering a container id
or leaving the code select normally.
Cd40 is configured at commissioning to read a valid container identification
number. The reading will not display alpha characters; only the numeric portion
of the number will display.
Cd41 Valve Override
SERVICE FUNCTION:
This code is used for troubleshooting, and allows manual
positioning of the economizer solenoid valve, electronic expansion valve, and
digital unloader valve. Provides readings such as: Percent Capacity, EEV,
Capacity Mode, LIV and DUV. See
Configurable Functions
- Cd43 is a user-selectable function. The operator can change the value of this function
to meet the operational needs of the container.
Cd43 XtendFRESH Mode
Cd43 has three selectable modes of operation:
FRESH - All XtendFRESH operations are enabled and setpoints for CO
2
and O
2
can be edited.
OFF - All XtendFRESH operations are disabled.
TEST - the operator has the ability to test operation of mechanical components,
test and calibrate the CO
2
sensors and verify the validity of the O
2
sensor.
