machine after the power recovery and after a download (default and custom values are
available for the ON/OFF, Temperature, Mode, Fan and Swing functions), whereas, on
its side, the latter permits selecting whether the related communication objects should
be sent or not to the KNX bus on power recovery or after a download.

Reset (Initial configuration)
Under the
default
configuration, after a power recovery IRSC Plus will
assume the same status it had (and therefore, the air conditioning machine)
before the power loss. This will not happen, however, after a download or a
device reset from ETS (the previous status will be lost during the download or
the device reset); in such case, IRSC Plus will assume ON/OFF=Off,
Temperature=25ºC, Mode=Cool, Fan=0%, Swing=Stopped.
Note
:
although IRSC Plus assumes the status it had before the bus power
loss, if during the interruption the A/C machine is externally manipulated or is
also affected by the power loss (most models do not automatically switch on
after a power loss), inconsistence between IRSC and the A/C unit may occur.
To avoid this, it is r
ecommended to enable the “Send reset configuration to
the split when reset occurs” parameter (explained below). Note that no orders
will be sent to the A/C unit on power recovery unless this parameter is
enabled.
Under a
Custom
configuration, it is possible to parameterise the following:
