e5 is comp overload code . if you have infared remote for indoor units point at anyone while pushing all 3 buttons at the same time- 'mode' 'temp up' temp down' this will bring up OO where temp set point is normally displayed. scroll up or down with temp up or down buttons (1st digit only) untill you here the beeping sound change tone, this is the 1st part of the fault code. press mode once to change to 2nd digit, scroll again with up and down listening for change of beep- 2nd part of code ie "E5". press mode again will bring up afunny looking T-test mode. press mode again to exit. THATS VERY ACCURATE SOLUTION.SAVE IT FOR FUTURE.WISH U SUCCESS .REPLY FOR FURTHER ASSISTANCE IF REQUIRED.BYE

The Energy Saver is not supposed to just shut down the unit, it cycles the unit on and off as room temperature alters.
Practically it put unit to rest when temperature is reached, and wake it up when temperature change again.
It is just a mode that turn the compressor earlier to save energy, but the compressor will still be working until temperature is reached.
