INFORMATION
Depending on the installed system, some operation modes will not be available.
▪ The air flow rate may adjust itself depending on the room temperature or the fan
may stop immediately. This is not a malfunction.
▪ If the main power supply is turned off during operation, operation will restart
automatically after the power turns back on again.
▪ Setpoint. Target temperature for the Cooling, Heating, and Auto operation
modes.
▪ Setback. A function that keeps the room temperature in a specific range when
the system is turned off (by the user, the schedule function, or the OFF timer).
The indoor unit can operate in various operation modes.

setpoint, or by Setback operation.
