NEW “I FEEL CONTROL” IN OUR LCD WIRELESS REMOTE CONTROLLER WITH ON/OFF PROGRAM TIMER
Mitsubishi Electric’s new wireless remote controller incorporates a number of advanced features that provide even greater con-
trol and ease-to- use. It has a liquid crystal display which indicates such infomation as mode, fan speed and temperature selected as well as the programmed ON/OFF time. It is also equipped with “I Feel Control”, a unique Mitsubishi Electric feature that allows the user to adjust the temperature to exactly the level he or she wants simply by tapping the button that describes present conditions : “Too Cool” or “Too Warm”. The optimum temperature set this way is then memorized for immediate recall whenever the air conditioner is used again. And what’s more, the new controller has been made more redesigned and easier to handle than before.
Select desired air flow direction. REMOTE-CONTROL OPERATION MODE
Using the remote controller, you can select from five airflow set-
tings to match room layout and the location of people. Also, you can set the vane to swing automatically.
Small in size, big on cooling. COMPACT INDOOR UNIT

AUTO-RESTART FUNCTION
The auto restart function restarts the equipment when power is
restored following an outage automatically. Operation resumes in the mode in which the equipment was running immediately before the outage.
HIGH PERFORMANCE ROTARY COMPRESSOR
The advanced design of Mitsubishi Electric’s powerful and energy-
efficient rotary compressor results in lower operating costs and longer service life.
