“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 information as mode, fan speed and temperature
selected as well as the programmed ON/OFF timer. 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.

Select desired air flow direction.
REMOTE-CONTROL OPERATION MODE

Using the remote controller, you can select from five airflow set­tings to match room layout and the location of people. Also, you
can set the vane to swing automatically.

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.

Inverter Technology

Outdoor unit uses inverter compressor technology (Variable Frequency Drive) to provide exceptional indoor high-speed
cooling and heating.
By responding to indoor temperature changes, the system reduces power consumption by varying the compressor speed for
extra energy savings and performs only to the levels needed to maintain a constant and comfortable indoor environment.

Extra Energy Savings

For optimum performance inverter technology controls the electrical current to the compressor, delivering only the energy
needed to match the cooling and heat load of a room. This feature reduces energy consumption.

High-Speed Heating and Cooling

Compressor rotation is controlled to maximize
efficiency, changing speeds according to the cooling
and heating load of a room. This application means
the desired temperature is reached much faster.

Optimum Comfort Year-Round

Unlike conventional units that start and stop repetitively,
inverter units are able to detect subtle changes in room
temperature and adjust airflow automatically. This adaptation
means less temperature variation and more comfortable rooms.
