Cd35 Bulb Mode The current state of the bulb mode option, “-----”, nOr, or bULb. (Re-
placed 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 un-
able to change it. CnF28 determines whether the bulb mode selection
is offered. After a dehumidification set point has been selected and en-
tered 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.
Cd36 Evaporator Fan Speed Select This is the desired evaporator fan speed for use during the bulb Dehu-
midification 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 al-
ternate their speed) and the display cannot be changed.
If a dehumidification set point 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 deac-
tivated 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 Tempera-
ture Sensor Cd38 will display the current supply recorder sensor (SRS) reading for
units configured for four probes. If the unit is configured with a Data-
CORDER, Cd38 will display “-----.” If the DataCORDER suffers a fail-
ure, (AL55) Cd38 will display the supply recorder sensor reading.
Cd39 Secondary Return Tempera-
ture Sensor Cd39 will display the current return recorder sensor (RRS) reading for
units configured for four probes. If the unit is configured with a Data-
CORDER, Cd39 will display “-----.” If the DataCORDER suffers a fail-
ure, (AL55) Cd39 will display the return recorder sensor reading.
Cd40 Container Identification Num-
ber 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 dis-
play “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 dis-
play will have Cd40 on the left display and the right display will alter-
nate 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 identifi-
cation number. The reading will not display alpha characters; only the
numeric portion of the number will display.
