Auto Cooling Model, Dry, Fan | Fujitsu AST9, AST7, AST12 guide

AUTO: COOLING MODEL

●Depending on the room temperature at the time operation begins, the operating mode will be switched automatically as shown in the accompanying table. Also, depending on the operating mode, the room temperature setting will cause the “standard” temperature to be set as shown.

Actual Room		Operating Mode		Thermostat Setting
Temperature				(standard setting)
30 °C or above →		Cooling	→	27 °C
27 to 30 °C	→	Cooling	→	26 °C
25 to 27 °C	→	Dry	→	24 °C
23 to 25 °C	→	Dry	→	22 °C
Below 23 °C	→	Dry	→	20 °C

The operating mode and standard thermostat settings are selected automatically when operation begins.

●When automatic operation is initiated, the fan will run at very low speed for about one minute while the unit detects and selects the proper operating mode.

●Once the operating mode has been set, the mode will not change even if the room temperature changes.

●If the START/STOP button is pressed to recommence operation within two hours after stopping automatic operation, the unit will begin operating from the same mode as before.

*Heating:

●Use to warm your room.

●When Heating mode is selected, the air conditioner will operate at very low fan speed for about 3 to 5 minutes, after which it will switch to the selected fan set- ting. This period of time is provided to allow the indoor unit to warm up before beginning full operation.

●When the room temperature is very low, frost may form on the outside unit, and its performance may be reduced. In order to remove such frost, the unit will automatically enter the defrost cycle from time to time. During Automatic De- frosting operation, the OPERATION indicator lamp (red) will flash, and the heat operation will be interrupted.

Cooling:

●Use to cool your room.

Dry:

●Use for gently cooling while dehumidifying your room.

●You cannot heat the room during Dry mode.

●During Dry mode, the unit will operate at low speed; in order to adjust room humidity, the indoor unit’s fan may stop from time to time. Also, the fan may operate at very low speed when detecting room humidity.

●The fan speed cannot be changed manually when Dry mode has been selected.

Fan:

●Use to circulate the air throughout your room.

* During Heating mode:

Set the thermostat to a temperature set- ting that is higher than the current room temperature. The Heating mode will not operate if the thermostat is set lower than the actual room temperature.

During Cooling/Dry mode:

Set the thermostat to a temperature set- ting that is lower than the current room temperature. The Cooling and Dry modes will not operate if the thermostat is set higher than the actual room temperature (in Cooling mode, the fan alone will oper- ate).

*During Fan mode:

HEAT & COOL MODEL (REVERSE CYCLE)

You can not use the unit to heat and cool your room.

During Fan mode: COOLING MODEL

●Fan operation begins when room tem- perature in the vicinity of the air condi- tioner rises above the set thermostat temperature; when the temperature drops, fan operation stops.

●If the air emitted feels too cool, raise the thermostat setting.
