1. Product features
Implemented core technology provides easy-to-use product operations that realize a comfortable
space.
1-1. Model lineup
1-2. Features
Powerful operation
Energy saving control by using human sensor
Implemented human sensor detects the presence or absence of human in a room by sensing
movement of occupants, and suppress both of the air conditioner operation and energy con-
sumption.

10 °C HEAT operation
The room temperature can be set to go no lower than 10 °C, thus ensuring that the room does
not get too cold when not occupied.
!
CAUTION
• When the room temperature is higher than 10 °C, 10 °C HEAT operation does not start. Oper-
ation starts and maintains the room temperature at 10 °C when the temperature drops below
10 °C.
• When 10 °C HEAT operation stops, the room set temperature quickly returns to the preset
temperature.
Outdoor unit low noise
Economy operation
5-mode timer (on, off, weekly, program, and sleep)
When air conditioner operates in large capacity, operation
noise of the outdoor unit will be suppressed. In case of the
room temperature being close to the set temperature,
operation noise might not decrease.
Economy operation is energy saving as the set
temperature of indoor unit is shifted by 1 °C, and the
maximum electric value of the outdoor unit is suppressed.
Example: Cooling operation
Weekly timer can be easily set by wireless remote controller.
On and off can be set up to 4 times in 1 day and up to 28 times in 1 week.
For other modes, program timer and sleep timer can be also selected by one
push.

Features
Simple function setting
Setting of the air conditioner selection function is performed by remote controller.
Weekly timer
Weekly timer can be easily set by wireless remote controller.
On and off can be set up to 4 times in a day, and up to 28 times in a week.
Program timer
The program timer operates the on and off timer once within a 24-hour period.
Sleep timer
The sleep timer function automatically corrects the temperature thermostat setting according to
the time setting to prevent excessive cooling and heating while sleeping.
• 5-mode timer setup (on, off, weekly, program, and sleep) available.
• Easy operation.
• Easy to change custom code (max. 4 custom code).
• Can be used jointly with wired remote controllers.
Cooling operation/Dry operation
When the sleep timer is set, the set temperature
automatically rises 1 °C every hour. The set
temperature can rise up to a maximum of 2 °C.
Heating operation
When the sleep timer is set, the set temperature
automatically drops 1 °C every 30 minutes. The
set temperature can drop to a maximum of 4 °C.
