1. NEW "I F E U CONTROL" IN OUR LCD WIRELESS REMOTE 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 Miibishi 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 : -To 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
Auto Stop Mode
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 (or lowers, when heating) the temperature setting by
1'F after one hour, and by another 1°F every half hour thereafter.
When two hours have passed, the air conditioner is running at a setting
that is 2°F higher, thus preventing excessive cooling.
Maximum temperature difference is 4°F for heating.
~ u t o m a t i cFan
' Speed Control
When there's a large difference between the set temperature and
existing room temperature, the fan speed automatically adjusts to HI to
either cool or heat the room quickly.
As the temperature differential decreases, the Fan Control shifts down
automatically to MED and LO. Operation is almost whisper quiet.

Hot Start System
Heating always begins comfortably with warm air, since the Hot Start System prevents cold air from being blown out at the
start of heating and during defrosting. (All heat pumps.)
Booster Heater for Fast Warm-up.
Microprocessor controlled-Booster Heater automatically hastens the heating process to quickly warm up a room, and thereby
eliminates unnecessary energy use that occurs during prologned heating. (All heat pumps.)
Automatic Change Vane System
The Automatic Change Vane System will automatically set the vane in a horizontal positiolifor cooling. During heating
when the hot air is blowing strongly enough, it will automatically adjust downward. The angle of the vane can be
adjusted with the Remote Controller. (MSH-12/15DN)
Adjustable Change Vane System
Choose the air direction that suits your needs. To achieve uniform
aimow for heating, adjust the louver downward. For cooling, keep it
in a horizontal position. (MS(H)-O9DW)
During heatiyl
Restart Function (Optional)
The restart function restarts the equipment when power is restored
following an outage, selecting as required either cooling or heating
operation at a fixed temperature setting of 75F. (MS-OgDW, MSH09DW, MSH-12/15DN)
High Performance Rotary Compressor
The advanced design of Mitsubishi Electric's powerful and energyefficient rotary compressor results in lower operating costs and a longer
service life.

3 . EASY OPERATION BY LCD WIRELESS REMOTE CONTROLLER
Once the controls are set, the same operation mode can be repeated by simply turning the POWER SW on.
When batteries are replaced all of the controls memories should be canceled and "I FEEL CONTROL" mode is automatically
selected.

NOTE Coil frost prevention during COOL mode of "IFEEL CONTROL"
.When the indoor coil thermistor RT12 is below 47'F for MS-09, 37'F for MSH-09, 27'F for MSH-12/15
for 5 min. the coil frost prevention mode starts. The compressor stops for 5 min. and the indoor fan runs
at set speed. The coil frost prevention mode may continues past 5 min. untill the indoor coil thermistor RT12
exceeds 47'F for MS-09, 37'F for MSH-09, 27°F for MSH-12/15.
The first 5 minutes, termination of Coil Frost Prevention is controlled by time regardless of the termination
temperature. After that the termination is controlled by the temperature regardless of time.
Therefore, Coil Frost Prevention continues at least 5 minutes even if the temperature reaches termination
point within 5 minutes. After 5 minutes, Coil Frost Prevention terminates if the temperature reaches to
termination point, or the mode will be prolonged untill the temperature reaches to the termination point.

- DRY mode of "IFEEL CONTROL" The system uses the same refrigerant circuit as the cooling circuit for dry operation.
The compressor and the indoor fan are controlled by temp. and by the microprocessor.
By such controls, indoor Row amounts will be reduced in order to lower humidity without much room temp. decrease.
The operation of the comp. and indoor fan is as follows on the next page.

Compressor operates by temperature control and time control.
In the first 2 min. the system is FAN mode and the indoor fan operates at VLO speed.
Then 2 min. later, the room temperature is read as the initial temperature.
@Set temp. is controlled to minus 2'F as initial set temp.
@When the thermostat is ON, the compressor repeats 8 min. ON/3 min. OFF cycle operation.
When the thermostat is OFF, the compressor repeats 4 min. OFF/1 min. ON cycle operation.
lndoor fan and outdoor operate in same cycle with compressor.
Indoor fan speed is VLO.

The fan runs when the indoor coil thermistor RT12 temp. exceeeds 7TF, when the temp. is below 64F, the fan stops.
(3) New warm air control.
When compressor starts in heating operation or after defrosting, the fan changes the speed due to the indoor coil
thermistor RT12 temp. to blow out warm air.
After releasing of cold air prevention, when the indoor coil thermistor RT12 is 113'F or above, the fan speed shifts to the
set speed.
When the indoor coil thermistor RTI2 is less than 113F, the fan speed is controlled by time as below.

After a compressor turn off by the thermostat, the indoor fan operates at a lower speed than LO.
NOTE :This speed is called Very Low (VLO) in this manual. When the compressor runs, the fan operates at the setting
speed. Due to the cold air prevention control, the fan does not start until the indoor coil thermistor RTI2 temp.
exceeds 72'F.
(5) If turn off the POWER button during heat operation, the indoor fan operates for 30 sec. LO speed to eliminate heat.

Defrost starting conditions
When all conditions of a) -- dl are satisfied, the defrosting operation starts.
a) Under heat mode of "I FEEL CONTROL" and heat operation, the compressor cumulative time exceeds the defrost interval.
b) The defrost thermistor RT61 is below 27°F.

d) Regarding MSH-12/15DN, discharge temp. ttiermistor RT62 is below 185°F.
Defrost stopping conditions
When the condition e) or f) is satisfied, the defrosting operation stops.
e) The defrost thermistor RT61 is above 37°F.
f) The defrosting time exceeds 1 0 min.
The defrosting operation stops forcedly by timer.
Defrost interval
The defrost interval is calculated by defrosting time.

EMERGENCY-TEST operation
When the remote controller is missing, has failed or the batteries run down, set the emergency run selector switch on the
front of the indoor unit to heat or cool and press the emergency run on/off switch. The unit will start and the operation lamp
will light.
The first 30 min. of operation will be the test run operation. This operation is for servicing. The indoor fan runs at high
speed and the system is in continuous operation. The thermostat does not operate and the timer is reset to normal.
After 30 min. of test run operation the system shifts to emergency run operation with a set temperature of 75°F in heating
or cooling. The fan s h i to MED speed.
This operation continues until the emergency run on/off button is pressed or a button on the remote control is pressed, then
normal operation will start.
The coil frost prevention circuit operates in this mode.

has priority. See page 27 for emergency-test run operation.
lO.COMPULSORY DEFROSTING MODE FOR SERVICE
Defrosting mode can be accomplished regardless of the defrost interval restriction by short-circuiting the connector
(CN606) on the outdoor P. C. board which is located in outdoor unit.
This compulsory defrosting mode should be started by the pulse based on the temperature sensed at the defrost thermistor
*
( R T1~) . Therefore,
as far as RT61 senses higher than 27'F, the compulsory defrosting mode connot be achieved.
RT61 is attached to the outdoor heat exchanger. See page 42 and 45 for the position of the connector CN606.

Self check function
This function is to show defective point by lighting or flickening of the indoor unit power lamp, defrost lamp, or "I FEEL"
monitor lamp (monitor LED). If troubles written in the below table occur during operation, the self check result indicated. The
abnormal point indication disappears by pressing the power on/off button of the remote controller and when the unit is on.
*Before taking measures make sure that the symptom reappears, for accurate troubleshooting
