(8) Left&Right swing control(only for the mode with this
function)
① After energization, swing motor will firstly have the vertical
louver rotate anticlockwise to position O to close air outlet. If
swing function has not been set after start-up of the unit, vertical
louver will turn clockwise to position D in heating mode, or turn
clockwise to position L in other modes.
② If swing function is set when turning on the unit, the vertical
louver will swing between L and D.
Vertical louver has 7 swing statuses:
◆ Stay at position L: control by remote controller:
◆ Stay at position A: control by remote controller:
◆ Stay at position B: control by remote controller:
◆ Stay at position C: control by remote controller:
◆ Stay at position D: control by remote controller:
◆ Swing between L and D: control by remote controller:
， ，
◆ Stop at any position between L and D (angles between L and
D are equiangular), control by remote controller: OFF
③ When turning off the unit, vertical louver will close at position O.
④ Swing action is valid only when swing command has been set
and the IDU fan motor is operating.
(9) Dual-8 nixie tube display
◆ When the air conditioner is turned on for the first time, dual-8
nixie tube defaulted to display current set temperature.
◆ When controller receives signal of display set temperature,
Installation and Maintenance
dual-8 nixie tube displays set temperature. When received
remote control signal is switched to indoor ambient temperature
display status signal from other display status, dual-8 nixie tube
will display indoor ambient temperature for 3-5s, and then turn
back to display set temperature. If remote control to set other
status, the display keeps the same.
◆ When air conditioner has a malfunction, dual-8 nixie tube will
show relevant error code.
◆ When air conditioner is in auto defrosting, heating icon will be
on and off.
◆ If turn off light button, all display will be turned off.
(10) Memory function
① Power failure when turning on the unit
◆ Memory content: ON status, mode, up&down swing, light, set
temperature, set fan speed, general timer, Fahrenheit/ Celsius
◆ General timer can be memorized. Time of timer is calculated
again from energization.
◆ Clock timer Can't be memorized.
② Power failure when turning off the unit
◆ Memory content: OFF status, mode, up&down swing, light, set
temperature, set fan speed, general timer, Fahrenheit/ Celsius
◆ General timer can be memorized. Time of timer is calculated

4. Special Function
(1) Health function (for the model with health function)
，
During operation of the IDU fan motor, press health button on
the remote controller to start health function (If there is not health
button on the remote controller, the unit defaults health function
ON).
(2) I Feel function (for all models, but it needs the remote
controller which can set this function)
When I FEEL command is received, the controller will operate ac-
cording to the ambient temperature sent by the remote controller
(For defrosting and cold air prevention, the unit operates accord-
ing to the ambient temperature sensed by the air conditioner).
The remote controller will regularly send ambient temperature
data to the controller. When the data has not been received for
a long time, the unit will operate according to the temperature
sensed by the air conditioner. If I FEEL function is not set, the
ambient temperature will be that sensed by the air conditioner.
