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 information 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 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.

AUTO-RESTART FUNCTION

The auto restart function restar ts 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.

MSM30NN MSM30NN2

This “3 to 1” Multi system (MSM30NN / MSM30NN2) consists of a single outdoor unit with three compressors that permit up to three indoor units to be installed separate rooms, each with its own controller.

SPACE-SAVING LAYOUT

Two or three indoor units are served by a single outdoor unit whose installation requires only minimum space. This allows equipment installed outside the house to be arranged in a neat, space-saving layout.

FLEXIBLE INSTALLATION OF INDOOR UNITS

Each indoor unit can be connected to piping up to 65 feet in length, providing plenty of freedom in determining the best locations for installation.

● The air coverage range is the value up to the position where the air speed is 1 ft/sec, when air is blown out horizontally from the unit properly at the High speed position. The coverage range should be used only as a general guideline since it varies according to the size of the room and furniture arranged in the room.
