Stop
The Operation mode, temperature setting and blow rate can be changed during the operation stop as well. When they are
operated during stop, the corresponding display area is indicated for several seconds.
After several seconds since the remote controller is operated, the setting of air-conditioner unit changes.
To operate the air conditioner every day with repetition of run/stop under the same conditions (operation mode, set tempera-
ture, blow rate and auto swing), step 1 ON/OFF alone is sufficient.
The condition previously set is displayed on the remote controller.
Quiet mode or a maximum performance mode on the FDT series can be set with dip switches on the circuit board of the indoor
control unit. (Factory settings differ depending on model.)
Avoid frequent operation of ON and OFF.
Do not use something with a sharp tip to press the remote controller switch.
During raising and lowering of the setting temperature by pressing the temperature setting switch, the
operation of unit may stop. This is caused from the activation of temperature controller and is not a
malfunction.

perature automatically. The adjustment by the blow rate switch is impossible.

flow volume are displayed in the remote control and operation begins at those auto run (exclusive cooler
unit: cooling) settings. Please set the run mode and temperature at a the desired levels.
In the case of automatic operation the [cooling] and [heating] operation are changed over automatically

perature constant.
