dOTE CONTROLLER

Mitsubishi Electric's new wireless remote controller incorporates a number of advanced features that provide even greater control and ease-of-use.

It

has a liquid crystal display which indicates such information as mode, fan speed and temperature

selected as well as the timer setting and time remaining.

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" "Too Warm", or "Okay" .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

compact and easy to handle than even before.

2.

A VARIETY OF MICROPROCESSOR-CONTROLLED FUNCTION

Automatic ON/OFF Timer Convenient timer function includes Auto Start, Auto Stop, both can be set 1-12 hours. Auto Stop (Night Setback) Mode. This mode raises the temperature setting by 1 "F after one hour, and by

another 1

"F the next half hour. When 1-1 /2 hours have passed, the air conditioner is running at a setting that is 2°F higher, thus preventing excessive cooling.

Automatic Fan Speed Control When there's a large difference between the set temperature and existing room temperature, the fan speed automatically adjusts to HI. As the temperature differential decreases, the Fan speed

shifts down

automatically to MED and LO.

Operation is almost whisper quiet. Adjustable Change Vane System Choose the air direction that suits your needs.

Keep it in a horizontal position to achieve uniform

aimow.

During cooling

Restart Function The restart function restarts the equipment when power is restored

following an outage.

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.
