SE Energy-saving mode active
What the display is showing
SE is shown on the remote when the energy-saving function is started in cooling mode (press TEMP and CLOCK together). The unit shifts the set temperature automatically to a factory energy-saving value, keeps the fan on auto and will not accept manual temperature or fan changes. Sleep and SE cancel each other. Not a fault.
