Off: Compressor stops.
Decrease: Decrease the running frequency to the lower level.
Hold: Keep the current frequency.
Resume: No limitation for frequency.
5.4.4 Auto-mode
This mode can be chosen with the remote controller and the setting temperature
can be changed between 62°F~86°F (17°C~30°C)
In auto mode, the machine will choose cooling, heating or fan-only mode according
to T ( T =T1-Ts).
T=T1-Ts
T > 3.6°F (2°C)
-3.6°F (-2°C) T 3.6°F (2°C)
T < -3.6°F (-2°C)
Table 9
Indoor fan will run at auto fan of the relevant mode.
The louver operates same as in relevant mode. If the machine switches mode
between heating and cooling, the compressor will keep stopping for 15 minutes
and then choose mode according to T1-Ts. If the setting temperature is modi ed,
the machine will choose running function again.
5.4.5 Drying mode
Indoor fan speed is xed at breeze (low fan) and can't be changed. The louver angle
is the same as in cooling mode. All protections are active and the same as that in
cooling mode.

5.4.6 Forced operation function
Forced cooling mode: The compressor and outdoor fan keep
running and the indoor fan runs at low speed. After running for 30
minutes, AC will turn to auto mode with 75.2°F (24°C) setting
temperature.
Forced auto mode: The action of forced auto mode is the same as
normal auto mode with 75.2°F (24°C) setting temperature.
When AC receives signals, such as switch on, switch off, timer on, timer
off, mode setting, fan speed setting, sleeping mode setting, follow me
setting, it will quit the forced operation.
5.4.7 Timer function
Timing range is 24 hours.
Timer on. The machine will turn on automatically when reaching the
setting time.
Timer off. The machine will turn off automatically when reaching the
setting time.
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.
Timer off/on. The machine will turn off automatically when reaching the
setting "off" time, and then turn on automatically when reaching the
setting "on" time.
The timer function will not change the system operation mode.
The system will quit the timer function when it has malfunction.
5.4.8 Sleep function
The sleep function is available in cooling, heating or auto mode.
Operation process in sleep mode is as follows:
When cooling, the setting temperature rises 1.8°F (1°C) (be lower than
86°F (30°C)) every one hour, 2 hours later the setting temperature stops
rising and the indoor fan is xed at low speed.
When heating, the setting temperature decreases 1.8°F (1°C) (be higher
than 62.6°F (17°C)) every one hour, 2 hours later the setting temperature
stops rising and indoor fan is xed at low speed. (Anti-cold wind function
has the priority).
Operation time in sleep mode is 7 hours. After 7 hours, the AC will turn
off and sleep mode will also be turned off.
Timer setting is available
