PROGRAM UPDATE
The Application software and BACnet database are
stored in the IPU II Flash memory. Copying a new ver-
sion of software and/or database from the SD Flash card
changes the IPU II Flash. The new application software
must be named SOFTWARE.BIN. The new BACnet
database must be named DATABASE.BIN. These files
must be located in the root directory of the SD Flash
card. The software can be updated without updating
the database. In this case, the existing database will be
used with the new software. The database cannot be
updated without updating the software.
To update the Program:
1. Copy the new software in to the root directory of
the SD card.
2. Rename this new program file SOFTWARE.BIN.
3. Turn the Unit Switch OFF.
4. Insert the SD card in to the SD card Reader/Writer
slot.
5. Press the OPTIONS Key and then press the Down
Arrow Key until FLASH CARD UPDATE DIS-
ABLED is displayed.
6. Press the RIGHT ARROW Key to change the DIS-
ABLED to ENABLED
7. Press the ENTER Key to start the update. Once the
ENTER Key is pressed the message FLASH CARD
UPDATING PLEASE WAIT... is displayed until
the update has been completed. The keypad and
display will not respond during the flash update.
Do not reset or power down the chiller
until the update is finished. Interrupting
the Flash Update procedure can corrupt
the program file and render the control
board inoperative.
8. After the software is finished updating, the con-
troller will automatically reboot.
9. If an error occurs during the update, an error mes-
sage will be displayed where XXXX is the Error

datalogging or else replaced with another SD card
dedicated for datalogging.

slightly then release the pressure. The card should
then pop out slightly to allow removal.
DATA LOGGING
A 2GB SD card (p/n 031-03466-000) may be inserted
into the 03478 IPUII SD card slot to record the chiller
operating parameters at 5 second intervals. The data is
stored in a folder named RMYYYYMM where YYYY
is the year and MM is the month the data was record-
ed. The controller creates a file for each day within
this folder with the format YYYYMMDD.csv where
DD equals the day of the month in addition to the
Y Year and M Month fields. For example: The folder
named RM201503 is a folder created in March of 2015.
Within this folder would be a file for each day of that
month that the datalogging is running. If a review of
the History Report shows that an abnormal event oc-
curred on March 3rd at 2:05pm, the user can import
the 20150303.csv file into Excel and look at the system
parameter details leading up to the 2:05pm event.
Follow all JCI Safety Directives when in-
serting or removing the SD card since the
card is located inside the control cabinet.
To start the Data Logging, insert the SD card into the
SD card slot on the 03478 IPUII board. The label on the
SD card should be facing outwards.
Once the SD card is inserted and the unit is powered up,
press the OPTIONS key. Then press the Down Arrow
key to advance to the DATA LOG TO FLASHCARD
selection. Next press the Right Arrow key to select ON
