FEATURES AND FUNCTIONS
■Energy saving and Comfortable function ■Remote controller
WIRED REMOTE CONTROLLER
The wired remote controller allows convenient control of indoor
unit operation.
WIRELESS REMOTE CONTROLLER (OPTION)
The optional wireless remote controller can be used. When
you use remote controller, there are following different points
as compared with using wired remote controller.
[The additional function for wireless ones]
• SLEEP timer
• TIMER
• 10 °C HEAT operation
And you can use both wireless and wired remote controller
simultaneously. (But function is limited.)
[The restricted functions for wired ones]
• Weekly timer
• Temperature set back timer
WEEKLY TIMER
Use this timer function to set operating times for each day of
the week. Use the DAY OFF setting to switch offtimed opera-
tion for a selected day in the coming week. Because all days
can be set together, the weekly timer can be used to repeat
the timer settings for all of the days.
TEMPERATURE SET BACK TIMER
Use this timer function to change the set temperature in the
operation times set for each day of the week. This can be used
together with other timer settings.
■Convenient function
INVERTER
At the start of operation, large amount of power is used to
bring the room quickly to the desired temperature. Afterwards,
the unit automatically switches to a low power setting for eco-
nomic and comfortable operation.
ECONOMY OPERATION
When ECONOMY operation mode is operated, the room tem-
perature will be little higher than the set-temp under cooling
mode and lower than set-temp under heating mode. Therefore,
the ECONOMY mode is able to save more energy than other
normal mode.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched auto-
matically to maintain the set temperature, and the temperature
is kept constant at all times.
