Table 4–6 Controller Function Codes (Continued)
The current state of the Bulb Mode option, "-----", nOr, or bULb.
(Replaced by Cd48 if CnF50, Enhanced Bulb Mode, is active.)
Bulb Mode is an extension of dehumidification control (Cd33). If dehumidification
(CnF04) is set to "Off," Cd35 will display "Nor" and the user will be unable to
change it. CnF28 determines whether the Bulb Mode selection is offered.
After a dehumidification setpoint has been selected and entered for code Cd33,
the user may then change Cd35 to "bulb." After Bulb Mode has been selected
and entered, the user may then utilize function codes Cd36 and Cd37 to make
the desired changes.
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 dis-
played (indicating that the evaporator fans will alternate their speed) and the dis-
play 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."
This is the variable defrost termination thermostat setting to be used with the op-
tional 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.)
Cd38 will display the current supply recorder sensor (SRS) reading for units con-
figured for four probes. If the unit is configured with a DataCORDER, Cd38 will
display "-----." If the DataCORDER suffers a failure, (AL55) Cd38 will display the
supply recorder sensor reading.
Cd39 will display the current return recorder sensor (RRS) reading for units con-
figured for four probes. If the unit is configured with a DataCORDER, Cd39 will
display "-----." If the DataCORDER suffers a failure, (AL55) Cd39 will display the
return recorder sensor reading.
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.
Pressing the Enter key on Cd40 will 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". Pressing the enter key while on Cd40 in the state will 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 num-
ber. The reading will not display alpha characters; only the numeric portion of the
number will display.
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, Ca-
pacity Mode, LIV and DUV. Refer to
