1. Automatic mode
1) The initial RT determines A/C working mode and setting temperature (ST), the mode is
determined effective only once unless A/C shut-down then re-started. If from other modes
switches to automatic mode (including mode conversion after shutdown), it should be that the
compress stop more than 3 min then temperature judgment and automatic mode are conducted (it
can conduct immediately from fan mode switched to automatic, the indoor fan stops, three minutes
later the response is made and start up). Within 3 min, the output as: Showing the room
temperature, indoor fans starts (or anti-cold airflow), the outdoor fan stops;
2) With auto re-start controller, once being turned off or in case of an accidently power cut, the A/C is
able to retain and restore the original mode when being turned on or the power supply is resumed,
if the auto restart function activated. power-down after power-on; while if the auto restart function
isn’t activated, the A/C enters standby state.

3. Dry mode
While select to this mode, the air conditioner operates for 3 minutes according to cooling mode firstly
(ST set at 7℃) , and then takes the detected backflow air temperature minus 2℃ as a new set
temperature (the minimum value of 5℃) and runs according to cooling mode, indoor fan operates at
low-speed, at this moment the setting operation of Fan speed is invalid but Swing is adjustable.
4. Fan mode
1) Indoor fan motor is running at setting speed (the speed is same as that of heating).
2) Vane motor control: running according to the setting condition.
3) The outdoor unit doesn’t work under fan mode.
5. Sleeping mode
1) Under sleep mode, the indoor fan motor is running at a low speed, except that the power light
and sleep light are on, timer light is on/off according to the setting state, running light is off. LED will
be off after displaying 30S.
2) Temperature control:
(1) From Cool mode to Sleep mode, one hour later, the operates Temp.=ST＋1°C，another one
hour later, the operates Temp.=ST＋2°C，after then unchanged.
(2) From Heating mode to Sleep mode, one hour later, the operates Temp.= ST-1°C，another one
hour later, the operates Temp.=ST-2°C，after then unchanged.
3) the machine will automatically shut up after running 10 hours under sleep mode.
Timer on start-up and sleep mode are implemented at the same time, and the sleep mode can not be
functioned.
6. Timing function
The timing scale is between 10min to 24h, when the time fixed is less than “10” hours, the displayed
time is shown by 0.5 hour as the unit, when the time fixed is more than or equal to “10” hours, the
displayed time is shown by 1 hour as the unit.
7. Emergency switch. （ON/OFF）
1) When stand-by, to operate by pressing the emergency switch as follows:
To Press the emergency switch in three seconds, the buzzer rings once, and to release, the machine
runs into cooling mode; if to holding on, the buzzer rings twice, then the machine runs into heating
mode, while when the machine is on, to press the Emergency switch, the buzzer rings once and then
the machine shut down.
2) The machine is running mandatorily as the selected mode within 30min after emergency operation,
indoor fan motor running in high-speed, and stepping vane swinging. The machine runs into
automatic mode 30min later, the selected mode unchanged, the set temperature to be 23° C, the
rotate speed of indoor fan motor is automatic, and stepping vane swinging also.
3) To press the emergency button when the machine operating, then the machine runs into stand-by.
4) Under emergency operation, the function of Compressor’s time-delay protection, anti-frosting
protection in cooling mode, Overheating protection in heating mode, sensor fault protection and
defrost operate are effective.
5) Under emergency operation, once effective signal from remote controller is received, then the
A/C exits form the emergency mode, and operate according to the setting value from remote controller.

four times.
9. Protection/ Troubleshooting.
1) Compressor’s protection:
a.The PCB which has Auto-restart function, once this function is started up, the compressor goes
along 3min delay protection when power on. If the PCB hasn’t been started up Auto-restart
function, even when the PCB is power-on, the compressor doesn’t process 3 min delay function.
b.The compressor’s 3 min interval protection: the compressor can’t start-up until it stops 3 min later.
(except for defrosting process).
c．After the compressor started, the compressor’s state isn’t subjected to the changes on ST,RT in 3min.
2) Anti-frosting protection of indoor evaporator (cooling mode):
If IPT ≤ 0 ℃ detected in consecutive 3 min, compressor and outdoor fan motor stopped, indoor fan
motor runs at high-speed forcibly; if IPT ≥ 5 ℃ detected 3min later, then outdoor fan mot or a n d
co m pr es s o r activated, indoor fan motor restores the original state.
3) The following table shows the fault protections. When failures happens, the PCB alarms and
buzzer rings three times. Failure code appears, and the PCB operates protection procedures.
Failure code: For the machine with LED display, the code shows on LED, for machine without LED,
the code reflects by the running light.
Failure

When failure happened, the code is displayed statically, if there are several failure codes should be
reported at the same time, then failure codes appears one by one every eight seconds
correspondingly.
a.
Sensor’s failure protection: when the sensor’s temperature is out of the range -50 ≤ T ≤ 110 ℃,
then sensor failure is determined. Once RT, IPT sensor failures appear, the compressor stops and
indoor and outdoor fan motors shut off. Remote controller doesn’t response to any signal except for
shutdown. During failure the machine can run in fan mode. After the failure is settled, the PCB
restores to standby status.
b.
Failure protection of Indoor PG fan motor: If there is no feedback signal of rotate speed within 5s,
the indoor fan motor stops, meanwhile, the compressor, outdoor fan motor, four-way valve and
auxiliary electric heater etc. cut down. 10 seconds later, the indoor fan motor restarts again, once
there is no feedback signal of rotate speed within 5 seconds either, then the machine stops and
goes into indoor fan motor failure protection, buzzer rings three times, and running light flashes at 6
times per 8 seconds. When the failure is confirmed, once there is feedback signal, the failure is
relieved automatic.
