
ON/OFF : after a bus failure, a download or a device reset, the A/C system
it will be possible to send the A/C system an order to recover the last
saved status
1
before the power loss or be switched off or on.

Temperature : after a bus failure, a download or a device reset, the it will
be possible to send the A/C system an order to recover the last setpoint
temperature (last saved position
1
) or a preset value ("Initial temperature",
in Celsius degrees).

Mode : after a bus failure, a download or a device reset, the A/C system
may be set to the last registered mode (last saved status
1
) or to one of the
following: Heat, Cool, Auto, Dry or Fan.

Fan : after a bus failure, a download or a device reset, the A/C system may
be required to recover the last registered fan level (last saved status
1
) or a
particular one: Auto, Low, Medium or High.

Swing : after a bus failure, a download or a device reset, the status of the
slats can be set to: Last saved status
1
, Swing or Stopped.
Note that for both, a default and for a custom configuration, the
“Send Reset
Configuration to the S
plit (when reset occurs)”
parameter needs to be enabled to
actually send the corresponding initial values to the A/C system on the power recovery.
If disabled, such IR commands will not be sent, but IRSC will still assume the
parameterised configuration as the initial state after the power recovery.
Important : it is recommended, in any case, to enable this sending to avoid
inconsistence between the state assumed by IRSC and that actually acquired by the
A/C unit once the power failure is solved. On the other hand, sending the
corresponding communication objects to the bus (so that the other devices in the KNX
environment are properly kept up to date
) may be enabled from the “Reset (Data
Update)” screen (see Section 3.5)

This specific option has no effect after downloads or device resets because the previous
status of the device is always lost; default values (ON/OFF=Off, Temperature=25ºC,
Mode=Cool, Fan=0%, Swing=Stopped) will be then assumed
