OPERATION OF WIRELESS REMOTE CONTROLLER

SLEEP MODE

The unit will automatically adjust room temperature during 
your sleep time. This slight change in temperature will not affect 
your comfort level due to the natural effects that sleeping has 
on the body, but it will save on energy consumption and will 
lower your electric bill. Press the SLEEP button to select Sleep 
Mode. The SLEEP        icon will appear.

In Cool or Dry modes:

If setpoint is between 61

to 73

, temperature will slowly 

increase 2

per hour for 3 hours, then maintain this setpoint 

for 4 hours, then reduce setpoint by 2

and hold at this 

setpoint until Sleep Mode is cancelled.

If setpoint is between 74

to 81

, temperature will slowly increase 2

per hour for 2 hours,

then maintain this setpoint for 5 hours, then reduce setpoint by 2

and hold at this setpoint

until Sleep Mode is cancelled.

If setpoint is between 82

to 85

, temperature will slowly increase 2

℉ 

per hour for 1 hour,

then maintain this setpoint for 6 hours, then reduce setpoint by 2

and hold at this setpoint

until Sleep Mode is cancelled.

If setpoint is 86

, unit will run at this setpoint for 7 hours, then reduce setpoint by 2

and

hold at this setpoint until Sleep Mode is cancelled.

In Heat mode:  

If setpoint is between 82 

to 86

, the unit will slowly reduce setpoint by 2

per hour for 

3 hours, and then maintain this setpoint until Sleep Mode is cancelled.  

If setpoint is between 69 

to 81

, the unit will slowly reduce setpoint by 2

per hour for 

2 hours, and then maintain this setpoint until Sleep Mode is cancelled.  

If setpoint is between 63

to 68

, the unit will reduce setpoint by 2

, and then maintain 

this setpoint until Sleep Mode is cancelled. 

If setpoint is 62

, the unit will run at this setpoint until Sleep Mode is cancelled.

X-FAN MODE

When operating in humid areas, the unit has a DRY COIL 
function called X-Fan that will allow the indoor fan to run for a 
pre-determined 

amount of time after the unit is turned off 

(cooling or dry modes) to ensure that additional moisture is 
removed from coil. Push the “

X-FAN

” button to enable this 

feature. The 

X-FAN

icon will be displayed on remote 

controller. To deactivate this feature, push the “

X-FAN

” 

button again.
