Night Set Mode
When the OFF Timer is set, the New Night Set Circuit automatically activates.
The Night Set Circuit automatically switches the fan speed to a low setting to minimize operating
noise. On the other hand, the New Night Set Circuit maintains the airflow setting made by users.
(Some models are equipped with an Night Set Circuit ON switch.)
The Night Set
Circuit
The Night Set Circuit continues heating or cooling the room at the set temperature for the first
one hour, then automatically lowers the temperature setting slightly in the case of cooling, or
raises it slightly in the case of heating, for economical operations. This prevents excessive
heating in winter and excessive cooling in summer to ensure comfortable sleeping conditions,
and also conserves electricity.

Self-Diagnosis Digital Display
The microcomputer continuously monitors main operating conditions of the indoor unit, outdoor
unit and the entire system. Should an abnormality occur, the LCD remote controller displays
information and the indicators on the indoor and outdoor units light. These indications allow
prompt maintenance operations.
1.1.19
Self-Diagnosis LED Display
The lighting patterns of the indoor unit LEDs (Operation, Timer and Dry/Hot Start indicators) and
the LEDs on the outdoor unit’s printed circuit board allow diagnosis of problem areas and faulty
conditions of the interconnecting wire.
Note:
Self-Diagnosis LED display is not equipped for FTK(X)25/35 J series.
1.1.20
Auto-Restart Function
Even if a power failure (including one for just a moment) occurs during the operation, the
operation restarts in the condition before power failure automatically when power is restored.
(Note) It takes 3 minutes to restart the operation because the 3-minute standby function is
activated.
