4. FAN Button
Pressing this button can set fan speed circularly as: auto (AUTO), low( ) ,medium( ),high( ).
Note:
● Under AUTO speed, the IDU fan motor will adjust the fan speed (high, medium or low speed) according to ambient temperature.
● Fan speed under dry mode is low speed.
● When selecting auto mode, Air conditioner will start auto operation according to indoor ambient temperature.Set temperature can’t be adjusted and will not be displayed as well. Press "FAN" button can adjust fan speed. Press " " button can adjust fan blowing angle.
● After selecting cool mode, air conditioner will operate under cool mode. Cool indicator " " on indoor unit is ON. Press "+" or "-" button to adjust set temperature. Press "FAN" button to adjust fan speed. Press " " button to adjust fan blowing angle.
● When selecting dry mode, the air conditioner operates at low speed under dry mode. Dry indicator " " on indoor unit is ON. Under dry mode, fan speed can’t be adjusted. Press " " button to adjust fan blowing angle.
● When selecting fan mode, the air conditioner will only blow fan, no cooling and no heating.All indicators are OFF.Operation indicator is ON.Press "FAN" button to adjust fan speed. Press " " button to adjust fan blowing angle.
● When selecting heating mode, the air conditioner operates under heat mode. Heat indicator " " on indoor unit is ON. Press “+” or “-“ button to adjust set temperature Press “FAN” button to adjust fan speed. Press " " button to adjust fan blowing angle.(Cooling only unit won’t receive heating mode signal. If setting heat mode with remote controller, press ON/OFF button can’t start up the unit).
Note:
● For preventing cold air, after starting up heating mode, indoor unit will delay 1~5minutes to blow air (actual delay time is depend on indoor ambient temperature).
● Set temperature range from remote controller: 60.8~86℉ ; Fan speed: auto, low speed,medium speed, high speed.
3. “+” or“-” Button
● Press “+” or “-“ button once increase or decrease set temperature 33.8℉.Holding "+" or "-" button, 2s later, set temperature on remote
controller will change quickly. On releasing button after setting is nished, temperature indicator on indoor unit will change accordingly. (Temperature can’t be adjusted under auto mode)
● When setting TIMER ON, TIMER OFF or CLOCK, press “+” or “-“ button to adjust time.(Refer to CLOCK, TIMER ON, TIMER OFF
buttons)
6. CLOCK Button
Press this button to set clock time. " " icon on remote controller will blink. Pess "+" or "-" button within 5s to set clock time. Each pressing of "+" or "-" button, clock time will increase or decrease 1 minute. Hold "+" or "-" button, 2s later, time will change quickly. Release this button when reaching your required time. Press “CLOCK" button to conrm the time. " " icon stops blinking.
Note:
● Clock time adopts 24-hour mode.
● The interval between two operation can’t exceeds 5s. Otherwise, remote controller will quit setting status. Operation for TIMER ON/TIMER OFF is the same.
