(9) Locked-rotor Protection of PG Motor
When starting up the fans, if the motor has run at a lower speed continuously for a period, in order to prevent
automatic protection of the motor, stop running, and display locked-rotor; if the machine is running at present, the
code of the locked-rotor fault---H6 of double-eight digital tubes will be displayed; if the machine is shut down at
present, the information of locked-rotor fault will not be displayed.
(10) Super Power Function
In cooling and heating mode (automatic, dehumidifying and air-supplying modes are without 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, at this time the remote controller is set at the Health function (if there is no
Health button on the remote controller, the order of starting Health is defaulted to be sent), then start the Health
function device.
5. Fault Detection of Thermo-bulb
(1) Indoor Environment Thermo-bulb:
Detect the fault of thermo-bulb at any time;
(2) Indoor Pipe Temperature Thermo-bulb:
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 Thermo-bulb:
1.When detecting that the thermo-bulb has 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 implement corresponding safety stops according to the over-high temperature sensed by the
thermo-bulb, and at the same time display corresponding temperature safety stops and faults of the thermo-bulb.
2. When detecting that the thermo-bulb has been 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
(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 mode of collecting fluorine, 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
ć
).
(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.
Outer Units
1. Input Parameter Compensation and Calibration
(1) Check the ambient temperature compensation function
Indoor ambient temperature compensation function
a. In cooling mode, the indoor ambient temperature participating in computing control = (T
indoor ambient temperature
–
Ƹ
T
cooling indoor ambient temperature compensation
)
b. In heating mode, the indoor ambient temperature participating in computing control= (T
indoor ambient temperature
–
Ƹ
T
heating indoor ambient temperature compensation
)
(2) Check parameter effective judgment controls
Effective judgment function of outdoor exhaust temperature thermo-bulb
When conditions a and b are satisfied, the outdoor exhaust temperature thermo-bulb is judged not to be
connected into place, the mainboard of outer units will display failure of the outdoor exhaust temperature
thermo-bulb (not connected into place), stop the machine for repairing, and resume the machine by remote
controls of ON/OFF.
a. Judgment of exhaust detection temperature change:
After the compressor starts up and runs for 10 minutes, if the compressor frequency f
≥ 40Hz, and the rising
value T
exhaust
(T
exhaust (after start-up for 10 minutes
) - T
exhaust (before start-up)
) < 2
ć
, the outdoor exhaust temperature
thermo-bulb can be judged not to be connected into place (judging once when power is on the first time).
b. Comparative judgment of exhaust detection temperature and condenser detection temperature (T
pipe temperature
= T
outdoor pipe temperature
in cooling mode, T
pipe temperature
= T
indoor pipe temperature
in heating mode):
After the compressor starts up and runs for 10 minutes, if the compressor frequency f ≥ 40Hz, and T
pipe temperature
≥
(T
exhaust
+ 3
ć
), the outdoor exhaust temperature thermo-bulb can be judged not to be connected into place
(judging once when power is on the first time).
