(8) Up and Down Swing Function

After turning on the unit, the louver will operate in the below angel. (if the remote controller is pressed
continuously within 2 seconds, the last signal will be executed, the previous signals will be invalid)
After energizing, the up and down swing motor will firstly rotate the louver to position 0 anticlockwise
(close in 138°) and close the air outlet. After turning on the unit, if swing function has been set, the louver will rotate to
position D clockwise in heating mode and auto heating mode; the louver will rotate to horizontal position L1 clockwise in
other modes. The indoor fan and compressor will be energized after the louver opens to position L1. If set the swing func-
tion while turning on the unit, the louver will swing between L1 and D. The louver will close to position L when turning off
the unit.

(9) Display

1. Upon energization within 2s, the unit will display all icons. Under standby state, running indicating mark
is displayed. If the unit is started by remote controller, running indicating mark gives off light; meanwhile, the
mark of current running mode will be di played. If the light button is turned off, no mark will be displayed.

0.5s and off for 10s.
3. In auto mode, the nixie tube displays 25 in cooling and fan, and displays 20 in heating.
4. The nixie tube displays set temperature.
5. When there is a malfunction or protection, if timer off is set, this function will be executed.

(10) Memory Function

Memorized items: mode, up & down swing, light, set temperature and set fan speed.
When power is recovered after power failure, the unit will automatically start operation according to memorized
status. After power recovery, the unit without timer setting before power failure will operate according to the last
setting; the unit with general timer setting which has not been fulfilled before power failure will memorize the
timer setting and re-calculate the time after power recovery. If there is timer function in the last remote control-
ler command but setting time has reached, the system will act as timer on/off setting before power failure. After
power failure, the system memorizes the operation states before power failure without timer action. Clock timer
can not be memorized.
