Function of the HMI buttons
The physical buttons of the display are divided in two sections:
▪ Commands: All the buttons on the right side are reserved for
basic commands of the unit. The functionality of these buttons
never changes, no matter which page is displayed.

commands. The functionality of these buttons can change
depending on the active page.
▪ Homepage (n):
Whatever page the HMI is showing, pushing the homepage button
(n) makes the HOME page appear.

To update the HMI and PCB software
There are two ways of updating:
▪ From a USB drive
▪ From telematics
The first way requires the operator to be physically in contact with
the Exigo 1500 to insert the USB drive in the USB Serial Port (a)
situated below the HMI (b).
INFORMATION
Only USB 2.0 flash drives (single partition, formatted as
FAT32) are compatible with the USB Host port. Do not
connect other USB devices. Max 100 mA.

The second way allows remote updating using the interface platform
with the telematics device of the unit.
The procedure for updating itself is the same for both ways.
To update the HMI software:
1 Go to Daikin Business Portal and download the update HMI
software in a .zip format named "UpdatePackage.zip" onto a
USB drive.
2 Turn the unit ON with the ON/OFF switch.
3 Insert the USB drive with the update files for the HMI or the
PCB software into the USB Serial Port of the HMI.
