(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

(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,
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.

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 but-
ton on the remote controller, the unit defaults health function ON).
(2) I Feel function (for all models, but it needs the remote con-
troller 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 tem-
perature will be that sensed by the air conditioner.
