The Mijia Air Conditioner Pro Eco 2.6 kW remote control display does not have a backlight. If the numbers and icons are displayed normally, the lack of illumination is a normal condition.
For your reference, here are the reasons why the air conditioner’s remote control does not include a backlight:
1. One reason for the lack of backlight is to conserve battery life. By not including a backlight, the remote control can operate for longer periods without needing frequent battery replacements. This design choice helps improve overall energy efficiency and reduces the need for maintenance;
2. By omitting the backlighting feature, Xiaomi reduces production complexity and overall costs. This allows the remote control to remain affordable while still providing all necessary functions for controlling the air conditioner efficiently.
