2.2.2 Emergency Run button: The unit will be turned off when pressing this button when the
unit is in operation
；
The unit will be turned on and operates in Smart mode after pressing this button when the
unit is in off status.
2.2.3 Press any key when the unit is in operation, the buzzer will give a buzz sound ; When
the unit is in off status, press the button of “on/off”, “air refresh” or “smart”, the unit will be
turned on with a buzz sound.
2.2.4 Please see the operating instructions for the usage of remote controller.
2.3 Blades Control
The blades range for vertical blades is from1-5 point position. Press “vertical airflow” button,
the blades will swing according to “1-2-3-4-5-swing-1-… “.But sometimes the blades can not
be controlled because the unit is in protect function.
2.3.1 Cooling, Dehumidification and Air refresh function:
The blades will swing circularly within the range of 1-4.
In cooling and dehumidification operation, louver blades can change the position
automatically to prevent from dripping.
2.3.2 Heating:
The blades will swing circularly within the range of 2-5.
During the course of heating beginning or defrosting
（
namely when the unit is in the pause
condition
），
the blades are in fixed position to avoid blowing cold airflow because of the too
low temperature of indoor evaporator. Only when the temperature of evaporator is higher
than 32
℃，
will the unit enter normal control.
2.4 Cooling
2.4.1 Indoor blower control:
The fan speed can be set as high, medium, low and auto level.
If changed to auto level, the indoor blower will choose the fan speed according to room
temperature and set temperature.
2.4.2 Cooling capacity control:
Calculating the difference value between the temperature detected by indoor pipe
temperature sensor and the prescribed indoor pipe value temperature to determine the
correction of frequency command signal, correct the frequency command signal currently
existing. When the indoor pipe temperature is lower than the prescribed indoor pipe value
temperature, the unit will decreases the rotary speed of compressor.
2.4.3 Freeze-prevention control:
Pipe coil sensor detects the temperature of indoor heat exchanger. If the temperature is
lower than the prescribed value, then the unit decreases the rotary speed of compressor to
keep the indoor heat exchanger from freezing. If the temperature exceeds the lower limit
