3 Other Control
(1)Timer function
The mainboard combines general timer and clock timer functions. Timer functions are selected by equipping remote controller with
different functions.
General Timer:
Timer ON can be set under off state of unit. If timer ON reaches, the controller will run under previous setting mode. Timing interval
is 0.5hr and the setting range is 0.5-24hr.
Timer OFF can be set under on state of unit. If timer OFF reaches, the unit is turned off. Timing interval is 0.5hr within the range of
0.5-24hr.
Clock Timer:
If timer on is set under running state of unit, the system will continue running. If timer on is set under off state of unit, the system will
run in presetting mode when timer on reaches.
If timer off is set under off state of unit, the system will keep standby state. If timer off is set under on state of unit, the system will
stop running when timer off reaches.
Timer Change:
If the system is under timer state, the unit can be turned on/off by ON/OFF button of remote controller. Timing can also be reset and
then the system runs according to the final setting.
If timer on and timer off is set at the same time under running state of system, the system will keep present running state till timer off
reaches and then it will stop running.
If timer on and timer off are set at the same time under off state of system, the system will keep stopping till timer on reaches and
then it will start running.
In the future, the system will run in presetting mode when timer on reaches and stop when timer off reaches every day. If timer on
and timer off have the same setting, timer off is prevails.
(2)Auto Button
If press this button, the system will run in auto mode, and the indoor fan motor will run at auto speed; meanwhile, the swing motor
will be running. Repress this button to turn off the unit.
(3)Buzzer
When the controller is energized or receives any command or signal from the buttons or the remote controller, the buzzer will give
out a beep.
(4)Sleep Function

(5)Turbo Function
This function can be set in cooling or heating mode.

)XQFWLRQDQG&RQWURO
(8)Up & Down Swing
After energization, up & down swing motor will rotate guide louver anticlockwise to position 0 to close air outlet.
After turning on the unit, if swing function has not been set, up & down guide louver will clockwise turn to position D in heating mode,
or clockwise turn to level position L in other modes.
If the unit is turned on with swing function setting, the guide louver will swing between W and D. There are 7 kinds of swing states of
guide louver: There are position L, A, B, C, D, and it swings and stops between L and D ( angle between L and D is equiangular).
Upon stop of unit, the guide louver will close to position O. Swing action is valid only when swing command is set and indoor fan is
running.
Note: If the position is set between L and B, A and C or B and D by remote controller, the guide louver will swing between L and D.
(9)Display
Running icon and Mode icon
Upon energization, the unit will display all icons. Under standby state, running indicating icon is displayed in red. If the unit is started
by remote controller, running indicating icon gives off light; Meanwhile, the present setting running mode icon will be displayed(mode
LED: cooling, heating and dry mode). If the light button is turned off, all icons display will be closed.
Dual-8 Display
After starting the unit for the first time, the nixie tube will display present setting temperature in default (16-30 ) the nixie tube will
default to display the preset temperature. When displaying setting temperature signal is received, the nixie tube will display setting
temp. If displaying ambient temperature signal is received, the nixie tube will display present indoor ambient temperature. If other
states are set by remote controller, the display will keep previous. If remote controller receives valid signal during displaying ambient
temperature, ambient temperature will be displayed after setting temperature is displayed for 5s. F1 is displayed for ambient
temperature sensor malfunction, F2 for tube temp sensor malfunction of indoor unit and C5 for jumper cap has malfunction.
Some models: The remote controller will display present setting temp when this display is set. The controller will display ambient
temp for 5s and then setting temp only when indoor ambient temp displaying state is switched from other displaying states by
remote controller.

)
Dry Function
This function can be set in cooling or dry mode.
(7)Automatic Control of Fan Speed
In this mode, the indoor fan will automatically select high, medium or low speed with the change of ambient temperature.
0 (0 degree)
(10)Locked protection to PG motor
When starting the fan, if motor’s rotational speed is slow for a period of time, the unit will display Locked and stop running to avoid
auto protection for motor. If the unit is on currently, error code H6 will be displayed by the dual-8 nixie tube. If the unit is off currently,
this locked malfunction information won’t be displayed.
(11)Power-off memory
Memory content includes mode, up&down swing, light, setting temp and setting fan speed.
Upon power failure, the unit after power recovery will automatically start to run according to memory content. The system, last
remote-control command without timer setting, will memorize the last remote-control signal and run according to it. If the last remote
controller command has general timer function and the system is de-energized before setting time, the system will memorize the last
timer function in remote controller command after re-energization and time will be recalculated. If there is function in the last remote
controller command but setting time has reached, the system will act as timer on/off setting before de-energization. After
re-energization, the system memorizes the running states before power failure without timer action.
