Automatic restart function

The unit is provided with an automatic restart function that allows
it to operate at the conditions selected before a power failure
occurred.
The unit will restart operation 3 minutes after the power supply
has been restored.
The unit is factory-supplied with this function disabled. It is
therefore necessary to select it, if the user needs it.

button in the lower right-hand corner under the indoor unit front
cover.
To activate the auto restart function, hold the EMERGENCY button
pressed for at least 3 seconds. The unit emits three beeps to
