Will user-related information be leaked after Gree air conditioning decoding?

No. In normal use, decoding will not reveal user-related information. Enter the bar code and engineering information of the unit, get a 6-digit password, and then start the machine through the input of the controller.

According to article 5.2.3 of GB/T 7725-2004 Room Air Conditioner, "The measured cooling power consumption of air conditioner should not be greater than 1 10% of its rated cooling power consumption", which means that the measured cooling power consumption of air conditioner is less than10% of its nominal value.

Taking Hisense's test product as an example, the rated cooling power consumption of this product is 820, the measured value is 87 1.8, and the measured value parameter is 106% of the rated value, which is less than 1 10%, which is also up to standard.

Expand the data 1, and replace the signal connecting wires of the internal and external machines.

2. If the fault still exists, please measure the power supply voltage of the signal port of the external board. If there is a voltage of 3.0V-5V, the communication is ok, and the fault should come from the frequency conversion motherboard or module;

3. If the power supply voltage of the signal port of the external unit board is about 0V- 1V, it means that the control circuit board of the indoor unit is abnormal. Replace it and try again.

4. If the outdoor frequency conversion module is very hot or the power supply voltage is abnormal, it means that there is something wrong with this module and it must be replaced with a new one.

5. The outdoor fan rotates slowly or does not rotate when rotating, indicating that the outdoor fan is abnormal. Try the machine again after replacement.

6. If the outdoor fan does not work, the compressor will stop and display E6 once it is started, which means that the main control circuit board of the outdoor unit may not supply power to the outdoor fan. Please check SCR and relay or replace the motherboard of outdoor unit, and then try again.
