★ In “DRY” mode, the “DRY” icon will light on. The inner fan will run at low fan speed in a

certain range. This DRY efficiency in this mode is more obvious than the one in COOL

mode, and the power saving efficiency is better.

★ In “HEAT” mode, the “HEAT” icon will light on. The setting temperature should be set up

higher than the present temperature; if it is lower than the present ambient temperature, the

HEAT mode is unavailable.

★ In “FAN” mode, the “FAN” icon will light on.

★ In “AUTO” mode, the “ AUTO” icon will light on, according to the ambient temperature, the

unit will automatically adjust the running mode.

★ In “HEAT” mode, when the outdoor temperature is lower and high humidity, and it frosted

in outdoor unit, and the heating efficiency will be reduced. If it is in this case, the controller will

start defrosting automatically, and displays “DEFROST” icon.

NOTE: There is no HEAT mode in the cooling only unit, after the power saving set up, the

auto mode will be shielded.

6) TIMER setup (Fig. 7)

At unit turned off, the timer on could be set up, at unit

Under normal condition, “ENV” will display the room

ambient temperature, at unit turned on, or unit turned off

status, press “SWING” button last for 5 seconds, the

LCD will display “OUT ENV”.

① If tested the outdoor temperature is the positive value,

that the setting temperature will not be displayed, the

original environment temperature displayer displays the Fig 8

system internal tested outdoor environment

temperature.

② If tested the outdoor temperature is the negative

value, the original environment temperature displays the

system inner tested the absolute value of the out

environment. After displayed the outdoor environment

temperature 10 seconds later, the system will back to

the room ambient temperature displaying surface. Fig 9

NOTE: If the unit has been unconnected with the outdoor ambient sensor, this

function will be unavailable.

8) SAVE set up (Fig.9)

At unit turned off, to press the “FAN” +“▼” buttons continuously for 5 seconds, adjust the Saver

set menu, at this time displays “SAVE” “COOL” icons, (if it is the first setup, that will display the

initial value:26℃), at the temperature setting district, it displays the lower limit temperature,and

the set temperature flashes, by pressing“▲”and“▼”buttons to set the cooling temperature lower

limit (the setting range is 16~30), press “ON/OFF” button to confirm; by pressing “▲” and“▼”

buttons to set cooling temperature upper limit, it will flash and display at ambient temperature,

( the setting range is 16-30) , and press “ON/OFF” button to confirm.

NOTE:The upper limit temperature should not be lower than the setting lower limit temperature.

If upper limit temperature is lower than the lower limit temperature, the system will default. The

higher is the upper limit temperature, the lower is the lower limit temperature. Press “MODE”

button, to complete the save setting in COOL, DRY mode, and transfer to the save setting in

HEAT mode (There is no the function in cooling only unit), at this time, it displays the “SAVE”,

“HEAT” icons, after setup has been completed, then press “FAN” +“▼” button last for 5 seconds,

and quit the SAVE setting operation. If the SAVE interface has been opened, the system will

respond to the last button input after 20 seconds, there is no any operation, the system will quit

the menu, and displays the normal unit off interface.

The above setting has been completed, the system will display ”SAVE” icon, no matter

by buttons on displayer or the wireless remote control, the setting temperature should not

exceed the former SAVE setup temperature range, for example as show in Fig. 9, we set up

the cooling lower limit is 23℃ in SAVE setting, the upper limit is 27℃ , the user can set the

cooling temperature between 23℃ to 27℃ by the wireless remote control and buttons on

displayer.

If the set up upper limit temperature is the same with the lower limit temperature that the

system only can run at the corresponding modes at the set temperature.

After the SAVE mode set up, at unit turned off, press the “FAN” +“▼” buttons for 5 seconds,

will quit the SAVE setting function, but the former

setting data will not clear, and the next time SAVE

setting will be the initial setting temperature.

After powered off, the SAVE setup function will be

memorized, the next time power on, the SAVE setting

is still active.

Set up the SAVE mode, the SLEEP, AUTO modes

will shield.

Press and hold the “MODE” key for 10 seconds when the unit is shut off to switch set values

so as to decide if the unit operating status or shut off status shall be memorized after a power

fail. If the set temperature area displays 01, it means the unit operating status or shut off status

shall be memorized after a power fail; 02 means the operating status or shut off status shall not

be memorized. Press the "ON/OFF" key to store the set value and exit the seting.

10) Malfunction display (Fig.11)

When the malfunction happened during operation, the displayer will display “ERROR” icon

and flash, and meanwhile will display the error code,

when there are multi-malfunction happened, the displayer

will display the error codes circularly. The first number

denotes the system number, if there is only one system in

the display, it will display the system number 1 , the

following two are error codes. For example as show in

right figure, that denotes the system 1, low-pressure

protection of compressor. Fig 11

The meaning of error codes as show in below:
