PCB.

Optional functions
The below functions’ programs are already write into the Main chip of the PCB, and can be performed
if only the corresponding hardware is available. For example: the E
2
CMOS chip is in need for the
Auto-restart function, the corresponding remote control is in need for the I feel function, and the relay
is in need for the Negative ion function.
①
Auto-restart control function
a)The setting method for Auto-restart function: After the controller being electrified, press the sleeping
button on the remote control for 10 times within 5seconds towards to the controller, later, if the
Auto-restart function is successfully set, there are four sounds delivered from the buzzer; If the
Auto-restart function need to be cancelled, press the sleeping button of the remote control for 10 times
within 5seconds towards to the controller, later, if the Auto-restart function is successfully cancelled,
there are two sounds delivered from the buzzer otherwise there is no sound
；
b) The contents memorized by the Auto-restart function are: operation modes, setting wind speed,
setting temperature, negative ion function, swing status and on-off condition.
c) After the setting of non-electricity memory function succeeds, when the non-electricity event
happens after turning off the air-conditioner normally, if re-electrify and turn on the air-conditioner,
there is no 3 minutes protection delay occurred to the compressor; when the non-electricity event
happens accidentally under the power-on status, if re-electrify and turn on the air-conditioner, there is
3 minutes protection delay occurred to the compressor;
d) If the setting of sleeping and timing functions occurs before the non-electricity event after
air-conditioner owns the Auto-restart function, the default condition of the controller is power-off
status after being electrified again.
I feel function
②
a)The setting method for I feel function: Press the “I feel” function button on the remote controller, the
controller will effect the I feel function once receiving the signal, and the controller herein will default
the temperature value of the sensor on the remote control as the previous TA of the controller
（
Except
the defrosting case
） ；
b) The quitting method for the I feel function
：
●
Press the I feel function button, the former I feel function setting will be cancelled at once;
●
Position the remote controller towards to the receiving window of the controller, the remote
control may deliver the signal to the controller every 3minutes. If the controller fails to receive the
signal from the remote control, the I feel function will be automatically cancelled, and the TA
control the temperature according to the temperature value detected by the TA sensor of the PCB.
c) When the I feel function starts, the controller doesn’t test the former TA sensor on the PCB.
③
Negative ion function
When the indoor fan is working, press the negative ion function button on the remote control, and the
