What does the letter W displayed on the remote control of Haier air conditioner mean?

There is a W sign under the heating of Haier air conditioner remote control, indicating that the air conditioner has turned on the auxiliary heating function.

The auxiliary heating function of air conditioner can improve the heating effect of air conditioner. Because when the air conditioner heats, the heat energy of the outdoor air is absorbed and converted to the indoor, but if the outdoor temperature is too low, the heating effect of the air conditioner is poor. The design of electric auxiliary heating is actually to improve the heating effect of air conditioning in cold weather. The air conditioner with electric auxiliary heating heats up faster, while the air conditioner without electric auxiliary heating heats up slightly slower.

Extended data:

The remote control is an electronic product, so handle it with care and don't throw it around at will.

Precautions for use:

1. The remote controller is a low-consumption product. Under normal circumstances, the battery life is 6 months. If the battery life is shortened due to improper use, two batteries should be replaced together. Do not mix old and new batteries or batteries of different models.

The remote control can't increase the function of your air conditioner. If there is no wind direction function on the air conditioner, the wind direction key of the remote control is invalid.

3. If the battery leaks, the battery box must be cleaned and replaced with a new battery. In order to prevent leakage, it is best to take out the battery when it is not used for a long time.

4. Ensure that the air conditioner receiver is normal and the remote controller is effective.

In another case, the remote control is good, and there is something wrong with the air conditioner remote control receiver. Open the shell of the air conditioner hanging machine, find the remote control receiver at the position of the display light, check whether the plug is loose, and wipe the dust of the remote control receiver with alcohol. Just try it. If it doesn't work, unplug the remote receiver and replace it with a new one.
