Fujitsu AST9 Air Conditioner User Manual

When set to AUTO:
* Heating : Fan operates so as to optimally circulate warmed air.
However, the fan will operate at very low speed when the temperature
of the air issued from the indoor unit is low.
Cooling : As the room temperature approaches that of the thermostat setting,
the fan speed becomes slower.
* Fan: HEAT & COOL MODEL (REVERSE CYCLE)
The fan alternately turns on and off; when on, the fan runs at the low
fan speed.
The fan will operate at very low setting during Monitor operation and
at the start of the Heating mode.
Fan: COOLING MODEL
The fan will operate at the optimum speed in accordance with the
room temperature in the vicinity of the indoor unit.
When set to QUIET:
SUPER QUIET operation begins. The indoor unit’s airflow will be reduced for qui-
eter operation.
SUPER QUIET operation cannot be used during Dry mode. (The same is true
when dry mode is selected during AUTO mode operation.)
During Super Quiet operation, *(Heating and) Cooling performance will be re-
duced somewhat.
To Stop Operation
Press the START/STOP button.
The OPERATION indicator lamp (red) (Fig. 3 5) will go out.
About Mode Operation
*AUTO (AUTO CHANGEOVER): HEAT & COOL MODEL (REVERSE CYCLE)
When AUTO CHANGEOVER operation is selected, the air conditioner selects the
appropriate operation mode (Cooling or Heating) in response to your room’s
temperature.
When AUTO CHANGEOVER operation first selected, the fan will operate at very
low speed for about one minute, during which time the unit detects the room
conditions and selects the proper operating mode.
When the air conditioner has adjusted your room’s temperature to near the ther-
mostat setting, it will begin monitor operation. In the monitor operation mode,
the fan will operate at low speed. If the room temperature subsequently changes,
the air conditioner will once again select the appropriate operation (Heating, Cool-
ing) to adjust the temperature to the value set in the thermostat. (The monitor
operation range is ±2 °C relative to the thermostat setting.)
If the mode automatically selected by the unit is not what you wish, see page 6
and select one of the mode operation (HEAT, COOL, DRY, FAN).
