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.
