Setting
When the unit is shut off, timing start can be set; After the unit is started up, timing
shutoff can be set. After the "TIMER" key is pressed, the unit enters the timing set
status and the word "TIMER" flashes on the display. Now user can press ( ) or( )
key to increase or decrease the set time. Press the "TIMER" key again and then the
timing shall go into effect. Now the unit starts to count the time passed. When the unit
is under timing status, you can cannel timing set by pressing the "TIMER" key. The
range of set time is between 0.5 to 24 hours.
When the unit is shut off, press the "FAN" key and the ( ) simultaneously for 5
consecutive seconds to activate the energy saving setting menu. Now "SAVE" and
"COOL" are displayed (In case it is the first time to set energy saving, the initial
value shall be displayed: 26. The lower limit of temperature shall be displayed on
the set temperature and the temperature value under setting shall flash. Set the
lower limit of cooling temperature using the ( ) key or the ( ) key (the lower limit

temperature can be selected from the range between 16-30). Press the "ON/OFF"
TIMER
key to confirm the setting; Also use the ( ) key or the ( ) key to set the upper limit
of temperature and the temperature value shall flash on the ambient temperature
area (OUT ENV area) (the upper limit temperature can be selected from the range
between 16-30). Press the "ON/OFF" key to confirm the setting. Please pay attention
that the upper limit temperature must be higher than the set lower limit
temperature; Otherwise the system shall regard the higher temperature as the
upper limit temperature and the lower one as the lower limit temperature. Press
the "MODE" key to complete the energy saving setting for the modes of cooling
and dehumidifying and turn to the energy saving setting for the heating mode
(Cooling only unit does not have this function). Now the LCD displays "SAVE" and
"HEAT". After setting is completed, press the "FAN" key and the ( ) key
simultaneously for 5 consecutive seconds to exit the setting of energy saving. After
the energy saving setting interface is activated, the system shall exit the interface
if there is no any operation within 20 seconds after the last key input, and the
normal shutoff status interface shall be displayed. After the above settings are
completed, the system shall display "SAVE". Now the set temperature shall not
exceed the temperature range of the energy saving setting before. For example,
the lower cooling limit is set as 23°C and the upper cooling limit is set as 27°C for
the energy saving temperature setting in left so the cooling temperature can only
be selected from the range of 23 °C to 27°C by using the remote controller or the
wire controller later. If the upper limit temperature is the same as the lower limit
temperature, the system can only operate at such temperature under relevant
modes. Remove of energy saving setting: To remove the energy saving setting
after it takes into effect, you can press the "FAN" and the ( ) key simultaneously
for 5 consecutive seconds when the unit is shut off. But the value set before will
not be cleared but as the initial set temperature for the next energy saving setting.
After the unit is disconnected to power supply, the energy saving setting shall be
stored. The setting still functions when the unit is connected to power supply
again. If the energy saving mode is set, the sleep mode and the auto mode shall be
