8.2 Upload confi guration from U SB pen drive
All k.Air models are equipped with a USB or micro USB host (Master) port that a USB mass storage device can be plugged into
(typically a USB pen drive or portable hard disk) so as to load a custom confi guration.
Procedure
1. Plug the pen drive into the USB Host port;
2. Proceed as described in the previous paragraph, selecting the “CUSTOM” option.
Important:
• Use only FAT formatted pen drives.
• Do not use mass storage devices with a current draw higher than 500 mA;
8.3 Load from auto- backup
k.Air, independently whenever the unit is switched ON, automatically backs up the unit confi guration. This is very useful for
restoring parameter settings following a software update, as it is the most recent active confi guration that was used by the unit.
Procedure
1. select the “AUTO-BACKUP” option and confi rm by pressing .
8.4 Manual confi guration
If choosing to confi gure k.Air manually, select “SKIP”
Then, using the menus, set the parameters that defi ne the unit composition and complete the fi ne- tuning procedure. The
recommended steps are as follows:
Unit>Confi guration menu
Set the composition of the air handling unit by enabling the various devices, such as fans, coils, dampers, etc.
This is also used to confi gure all of the common parts between the various devices, such as control probe, heating/cooling
mode selection, frost protection etc.
Device menu
For each device enabled (fans, coils, dampers etc.), a specifi c menu will be available for fi ne-tuning the unit. Scroll through all of
the menus proposed for the devices
In/Out>Confi guration menu
After the devices have been enabled in the previous menus, only the inputs or outputs needed for correct operation of the unit
will be shown. Assign a channel for each point proposed. See the chapter on Input/output confi guration
Unit>Set point and scheduler menu
Confi gure the scheduler (if featured) and the reference set points
It is recommended to export the unit confi guration via screen Ac99 (see chapter 8.10)
Once the confi guration of the unit has been completed by choosing the preloaded confi gurations, custom confi guration fi le or
manual guided procedure, the unit shows the main screen and is ready to be switched on. It is always recommended to reboot
the unit.
Important: it is recommended to carefully check the parameters before switching the unit on, so as to avoid possible mal-
functions relating to an incorrect confi guration.
