How do I turn on the FHWC054TE1 air conditioner?

Press the On/Off button to turn on the unit. The unit will run in Eco (energy saver) mode when powered on each time if the last shutdown was in cool or Eco mode. In this mode, the fan will continue to run for 3 minutes after the compressor shuts off, then cycle on for 120 seconds at 10 minute intervals until the room temperature rises above the set temperature.
