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.
