Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning temperature control, in particular to a temperature control circuit on an air-conditioning panel. Background Art

[0002] The temperature control panels of air conditioners commonly used on the market currently use different icons to identify different working modes. For example, the cooling mode is a snowflake icon and the heating mode is a sun icon. However, in actual use, no matter which working mode is used, the digital icon for setting the temperature or the mode icon is displayed in a single color, which makes it difficult to distinguish the working modes. Users can only confirm whether the current working mode is the mode they set by checking the mode icon. This is extremely inconvenient to use, especially for children or elderly people with poor eyesight. Summary of the Invention
