… Point of rating condition
Black dot in the chart indicates the following rating condition.
Indoor: 70°F (21.1°C) D.B.
Outdoor: 47°F (8.3°C) D.B. / 43°F (6.1°C) W.B.
2) Above characteristics indicate instantaneous operation, which does not take into account defrost
operation.
3) Fan speed: High
4) Because this air conditioner heats a room by drawing in the heat of the outside air (heat pump system),
the heating efficiency will fall off when the outdoor temperature is very low. If sufficient heat cannot be
obtained with this air conditioner, use another heating appliance in conjunction with it.

7-3. Address Switches
If you are installing more than 1 indoor unit (up to 2) in
the same room, it is necessary for you to assign each
unit its own address so each can be operated by its own
remote control unit. You assign the addresses by
matching the switch positions of each indoor unit with
the switch positions of its remote control unit. The
switches of the remote control unit are shown in Fig. 8.
For instance, to set up 2 indoor units, switch Unit A’s
address switches. Then switch Unit B’s address switch-
es. It is important that you match the switches of the air
conditioner unit with the switches of its remote control
unit.

8-2. Dry Operation (Dehumidification)
●
Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to
dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of turning ON
and OFF automatically as shown in the chart below according to the room temperature.

Both the indoor and outdoor units stop.
NOTE
● Intermittent ventilation occurs by switching the indoor fan speed between L ↔ LL.
● Dry operation does not occur when the room temperature is under 15°C, which is the monitor zone.
● When the compressor stops, the indoor fan stops as well.
8-3. Automatic Switching between Cooling and Heating
●
When AUTO mode is selected, the microprocessor calculates the difference between the set temperature and
the room temperature, and automatically switches to COOLING or HEATING mode to maintain the desired tem-
perature.
Room temp. ³ Set temp. ➞ COOL
Room temp. < Set temp. ➞ HEAT
This means that if the room temperature is higher than or equal to the set temperature, COOLING operation
begins. If the room temperature is lower than the set temperature, HEATING operation begins.

8-4. Freeze Prevention (Cooling)
●
●
This function prevents freezing of the indoor heat exchange coil.
When the compressor has been running for 10 minutes or more and the temperature of the indoor heat
exchange coil falls below 30°F, the control circuit stops the compressor for at least 6 minutes. The compressor
does not start again until the temperature rises above 46°F or 6 minutes has elapsed.

●
This function protect the compressor from being damaged due to flow back of the liquid refrigerant to the com-
pressor when the outdoor temperature is very low.
●
Low ambient operation during heating can cause the outdoor heat exchanger to become super–cooled which
may result in liquid back–flow. To protect the compressor from this condition, both compressor and outdoor fan
stop if the outdoor temperature drops around 5°F. However, the indoor fan continues to operate even after the
compressor has stopped. Note that standby lamp does not lights up during this period.

Special Remarks
``DRY'' ( ) Operation
How it w orks?
•
Once the room tem perature reaches the level that was set, the unit
repeats the cycle of turning on and off autom atically.
During DRY operation, the fan speed is autom atically set to LOW or
•
VERY LOW; the fan speed then switches back and forth between
LOW (for 20 seconds) and VERY LOW (for 10 seconds).
“DRY” operation is not possible if the indoor tem perature is 59°F or
less.
•
Heating ( ) Operation
Heating perform ance
•
Because this air conditioner heats a room by drawing in the heat of
the outside air (heat pum p system ), the heating efficiency will fall off
when the outdoor tem perature is very low. If sufficient heat cannot
be obtained with this air conditioner, use another heating appliance
in conjunction with it.
•
Defrosting
When the outdoor tem perature is low, frost or ice m ay form on the
heat exchanger coil, reducing heating perform ance. When this
happens, a m icrocom puter defrosting system operates. At the sam e
tim e, the fan on the indoor unit stops and the STANDBY lam p
rem ains lit until defrosting is com pleted. Heating operation restarts
after several m inutes. (This interval will vary slightly depending
upon the outdoor tem perature and the way in which frost form s).
•
STANDBY lam p
For several m inutes after the start of heating operation, the indoor
fan will not start running until the indoor heat exchanger coil has
warm ed up sufficiently. This is because the COLD DRAFT
PREVENTION SYSTEM is operating. During this period, the
STANDBY lam p rem ains lit.
STANDBY lam p
OPERATION STANDBY TIMER
•
The STANDBY lam p also rem ains lit during defrosting or when the
com pressor has been turned off by the therm ostat when the system
is in the heating m ode.
•
Upon com pletion of defrosting and when the com pressor is turned
on again, for heating operation, the STANDBY lam p will go off
autom atically.
•
In the event of power failure, the unit will stop. When the power is
resum ed, the unit will restart autom atically after five m inutes.
