After completing above setting, the system will display SAVE-ENERGY icon on the LCD when the unit is
turned on next time. In this case, no matter from the wired controller or remote controller, the user is
unable to set the temperature beyond the range defined during the previous SAVE-ENERGY setting. As
shown in Fig. 9, we have set the lower limit of cooling to 23 and the upper limit to 27 . After that, the ℃℃
user can only set the cooling temperature between 23~27 no matter from remote controller or wired ℃
controller.
If the upper limit temperature is equal to the lower limit, the system can only run at this temperature
setting under corresponding mode.

simultaneously press “FAN”+“▼” buttons under turn-off state and hold them for 5 seconds to release the

next time.
Once set to SAVE-ENERGY mode, the SLEEP mode and AUTO mode will be shielded.
