    RAS – Auto Restart Function The indoor unit is equipped with an automatic restart facility that allows the unit to restart, at the last set operating conditions, after a power failure. The operation will resume without warning three minutes after power is restored. This feature is not set up when these systems are shipped from the factory, therefore it will need to be activated by the installing company.
