 HIGH POWER

Raises the power but remains in the same operating mode.
This function is set with the HIGH POWER button on the remote 
controller.
(It is set regardless of the temperature and fan speed settings.)

 HIGH POWER operation from the remote controller

  The unit operates at maximum output for 15 minutes, 

regardless of the desired temperature.

  The fan speed is 1 step above “High.”

NOTE
•  When HIGH POWER operation ends, the unit operates at low 

Hz for 5 minutes, regardless of the thermostat OFF conditions.

•  When in DRY mode, operation is in the cooling zone.
•  When in HEAT mode, defrosting does not occur during HIGH 

POWER operation.

•  If HIGH POWER is set while defrosting is in progress, HIGH 

POWER operation begins after defrosting ends.

•  HIGH POWER operation cannot be set from the remote 

controller when the unit is stopped.

•  HIGH POWER operation and ECONOMY operation cannot be 

used at the same time. The function set last takes priority.

NOTE
  This function does not operate if the ON timer standby time is 

less than 30 minutes.

•  Operation starts when the time set for the ON timer is reached. 

When a time is set, the TIMER lamp illuminates.

•  The below comfort timer programming is performed. 

A comfort time is calculated from the set temperature and the 
room temperature, either 60 minutes prior or 30 minutes prior to 
the set ON timer time, and operation is started in advance of 
the set ON time. (The indoor fan speed is “Medium.”)

  [COOL] 

Indoor temperature – Set temperature = Temperature difference

  [HEAT] 

Set temperature – Indoor temperature = Temperature difference

 OFF timer operation

•  Operation stops when the time set for the OFF timer is 

reached.

  When a time is set, the TIMER lamp illuminates.

 Timer backup

•  If the indoor unit is unable to receive the timer time-end signal 

when the ON or OFF time is reached, then timer time-end 
occurs according to the indoor unit backup timer within 
approximately 26 minutes.

•  Operation stops if there are no operator controls for 25 hours or 

longer after unit operation switched from OFF to ON by use of 
ON timer operation.

The indoor unit and outdoor unit fan speeds are 
automatically lowered for quiet operation.

  •  The temperature setting is lowered by 3
