indoor fan runs as breeze. After running for 30
minutes. the machine will turn to auto mode as
24
℃
setting temperature.
Forced auto mode:
The action of forced auto mode is the same as
normal auto mode with 24
℃
setting
temperature.
9.4.7 Timer function
9.4.7.1 Timing range is 24 hours.

9.4.8.1 Operation time in sleep mode is 7 hours.
After 7 hours the AC quits this mode and turns
off.
9.4.8.2. Operation process in sleep mode is as
follow:
When cooling, the setting temperature rises 1
℃
(be lower than 30
℃
) every one hour, 2 hours
later the setting temperature stops rising and
indoor fan is fixed as low speed.
When heating, the setting temperature
decreases 1
℃
(be higher than 17
℃
) every one
hour, 2 hours later the setting temperature
stops rising and indoor fan is fixed as low speed.
(Anti-cold wind function has the priority)

will not stop until reaches the setting time in
sleep mode.
9.4.9 Auto-Restart function
The indoor unit is equipped with auto-restart
function, which is carried out through an
auto-restart module. In case of a sudden power
failure, the module memorizes the setting
conditions before the power failure. The unit will
resume the previous operation setting (not
including swing function) automatically after 3
minutes when power returns.
If the memorization condition is forced cooling
mode, the unit will run in cooling mode for 30
minutes and turn to auto mode as 24
℃
setting
temp.
If AC is off before power off and AC is required
to start up now, the compressor will have 1
minute delay when power on. Other conditions,
the compressor will have 3 minutes delay when
restarts.
9.4.10 Automatic panel function
8.4.10.1 The automatic panel is forced to turn
to the closing direction at an angle of 50°when
the unit is getting through the power, and this
action is not affected by any signal from remote
controller.
9.4.10.2 When the unit is turned on, the panel is
opened automatically at an angle of 50°, then
the horizontal louver will be opened.
9.4.10.3 When the unit is turned off, the panel is
closed automatically at an angle of 50°, then
the horizontal louver will be closed.
9.4.10.4 If the panel needs moving when the
horizontal louver is in action, the unit will stop
the horizontal louver and then carry out the
action of the panel. After ending the action of
the panel, the horizontal louver will continue its
action.
