Universal remote control knowledge

Universal remote control is a type of remote control that can control multiple electronic devices. By learning or pre-set codes, it can identify and control devices of different brands and models. ‌
The principle of universal remote control

The universal remote control expands the internal memory of the chip and integrates the codes of hundreds or thousands of different models of remote controls into a single transmission circuit. Each encoding format corresponds to a code, and when used, the corresponding code is retrieved based on the code and activated through various functional buttons
How to use the universal remote control

Manual setting: Find the model code corresponding to the air conditioner that needs to be remotely controlled from the "Code Table", and turn on the power of the air conditioner. Press the "Settings" button continuously until the desired code is displayed on the window and flashes. This model code corresponds to code 2 of the air conditioner.
Auto search: Turn on the power of the air conditioner, point the remote control directly at the air conditioner receiver, press the "Settings" button repeatedly until the air conditioner automatically turns on/off, and press the "Confirm" button to save
