(9) Locked Protection of PG Motor

When starting up the fans, if the motor has run at a lower speed continuously for a period, for preventing

automatic protection of the motor, stop running, and display the locked operation; if the machine is running at

present, the code of the locked fault---H6 of double-eight digital tubes will be displayed; if the machine is shut

down at present, the information of the locked fault will not be displayed.

(10) Super Power Function

In cooling and heating modes (automatic, dehumidifying and air-supplying modes are without strong power),

press the button of Super Power, the wind speed on the remote controller is displayed as super-high air flow, and

the inner fans are also turned to super-high air flow;

(11) Health Function

When the inner fans are running, the remote controller is set at the Health function at this time (if there is no

Health button on the remote controller, the Health On order is defaulted), then start the Health function device.

5. Fault Detection of Temperature Sensor

(1) Indoor Environment Temperature Sensor:

Detect the fault of thermo-bulb at any time;

(2) Indoor Pipe Temperature Temperature Sensor:

During the defrosting period, the fault of the thermo-bulb will be not detected, which shall be detected in 5

minutes after defrosting is completed; the fault of the thermo-bulb will be detected at other times;

(3) Protecting Treatments of Temperature Sensor:

1.When the thermo-bulb is detected to be short-circuited continuously for 30 seconds:

It is regarded that the temperature detected by the thermo-bulb is over-high (or unlimited), then the whole

machine will exert corresponding safety stops according to the over-high temperature sensed by the thermo-bulb,

and display corresponding temperature safety stops and faults of the thermo-bulb simultaneously.

2. When the thermo-bulb is detected in open circuit continuously for 30 seconds: stop the machine in protection,

directly display corresponding faults of the thermo-bulb.

6. Forced Running Function of the Inner Units

(It is refrigerants reclaiming function which is used for the condition that refrigerants cannot be reclaimed by

cooling operation in the season with low temperature.)

(1) Enter into Forced Running Control

Within 5 minutes after power-up, press the Lights Off button on the remote controller continuously for three

times within 3 seconds to enter into the fluorine collecting mode, and display Fo, send the fluorine-collecting

mode for 25 minutes continuously, each load will be treated as cooling when starting the machine (set the air flow

as High, set the temperature as 16 ).

(2) Exit from the Forced Running Control

After receiving any remote signal, or signal of keys, the fluorine-collecting mode will exit, and operate in

accordance with the current orders set; or exit the fluorine-collecting mode after running for 25 minutes, and the

machine will be shut down automatically.

1. Input Parameter Compensation and Calibration

(1) Check the ambient temperature compensation function

If discharge temperature sensor breaks away, the unit will warn and stop running. By pressing ON/OFF on

remote controller, it can be cleared.

2. Basic Functions

(1) Cooling Mode

1. Conditions and processes of cooling operation:

(1) If the compressor is shut down, and [T

)] ≤ 0.5 , start up the machine for cooling, the cooling operation will start;
