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
timing is less than 7 hours, sleep function will be cancelled when reaching the setting time. If the timing
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(optional)
In heating operation, the preset temperature of the air conditioner can be as lower as 8℃, which keeps the room
temperature steady at 8℃ and prevents household things freezing when the house is unoccupied for a long time
in severe cold weather.

Frequency limitation protection
The PCB will detect the voltage of power supply and adjust the compressor running frequency to protect the
