• The rotation operation can be set only when controlling 2 refrigerant systems of
Single split system (combination of 1 outdoor unit and 1 indoor unit) by one remote
controller.
Backup operation
The backup operation is a support operation performed by a refrigerant
system in standby mode when the room temperature does not reach the
set temperature due to poor performance or occurrence of an alarm.
Example: When an error occurs while System 1 is in operation and System 2 is in
standby, System 2 will start up.
