8.4.7.3 Timer off. The machine will turn off automatically when reaching the setting time.
8.4.7.4 Timer on/off. The machine will turn on automatically when reaching the setting "on" time, and
then turn off automatically when reaching the setting "off" time.

8.4.7.6 The timer function will not change the AC current operation mode. Suppose AC is off now, it will
not start up firstly after setting the "timer off" function. And when reaching the setting time, the timer
LED will be off and the AC running mode has not been changed.
8.4.7.7 The setting time is relative time.
8.4.8 Sleep function mode
8.4.8.1 Operation time in sleep mode is 7 hours. After 7 hours the AC quits this mode and turns off.
8.4.8.2. 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)
8.4.8.3 Timer setting is available
8.4.8.4 When user uses timer off function in sleep mode (or sleep function in timer off mode), if the

is more than 7 hours, the machine will not stop until reaches the setting time in sleep mode.
8.4.9 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.
8.4.10 8℃ Heating
