Verify that the unit is connected to the
main power and the STANDBY lamp is
light up.
1.Set the MODE selector to COOL .
2.Press the ON/OFF button and switch the
air condioner ON.
3.Press the TEMP. buttons to set the desired
temperature (the temperature range is
between 32 °C max. and 16 °C min.).
NOTE
1.Set the MODE selector to HEAT .
2.Press the ON/OFF button and switch the air condioner ON.
3.Press the TEMP. buttons to set the desired temperature (the
temperature range is between 32 °C max. and 16 °C min.).
THE DISPLAY SHOWS THE SELECTED
TEMPERATURE.
AFTER 5 SECONDS FROM THE REQUIRED
TEMPERATURE SETTING THE DISPLAY WILL
SHOW THE ROOM TEMPERATURE AGAIN.
4.Press the FAN button to select the fan speed.
For several minutes after the start of heating operation, the
indoor fan will stop until the indoor heat exchanger coil has
warmed up sufficiently. This is because the COLD DRAFT
PREVENTION SYSTEM is operating. During this period, the
STANDBY lamp remains lit.
NOTE
DEFROSTING OF THE EXTERNAL HEAT
EXCHANGER
When the outdoor temperature is low, frost or ice may
appear on the heat exchanger coil, reducing the heating
performance. When this happens, a microcomputer
defrosting system operates. At the same time, the fan in
the indoor unit stops and the STANDBY lamp remains lit until
defrosting is completed. Heating operation restarts after
several minutes. (This interval will vary slightly depending
on the room and outdoor temperature).
HEATING PERFORMANCE
A heat pump conditioner heats a room by taking heat from
outside air. The heating efficiency will fall off when the
outdoor temperature is very low. If enough heat is not
obtained with this air conditioner, use another heating
appliance in conjunction with it.
1.Set the MODE selector to AUTO .
2.Press the ON/OFF button and switch the air condioner
ON.
3.Press the TEMP. buttons to set the desired temperature
(the temperature range is between 32 °C max. and 16 °C
min.).
When this setting is selected, the air conditioner calculates
the difference between the thermostat setting and the room
temperature and automatically switches to the COOL or
HEAT mode as appropriate.
4.Press the FAN selector button to the setting you want.
THE DISPLAY SHOWS THE SELECTED
TEMPERATURE.
AFTER 5 SECONDS FROM THE REQUIRED
TEMPERATURE SETTING THE DISPLAY WILL
SHOW THE ROOM TEMPERATURE AGAIN.
Example of operation diagram in the (Auto) mode with
the set room temperature at 23°C.
NOTE
The air conditioner changes the operation mode (from cool
to heat or vice versa, if one of the following conditions
occurs:
- ZONE A: changes if the difference between the room
temperature and the temperature set on the remote control
unit is at least 3°C..
- ZONE B: changes if the difference between the room
temperature and the temperature set on the remote control
unit is at least 1°C, one hour after the compressor stop.
- ZONE C: never changes if the difference between the
room temperature and the temperature set on the remote
control unit is no more than 1°C.
DEHUMIDIFYING (DRY)
1.Set the MODE button to DRY. The icon is displayed.
2.Press the ON/OFF button and switch the air condioner ON.
3.Press the TEMP. buttons to set the desired temperature (the
temperature range is between 32 °C max. and 16 °C min.).
