<In cooling operation>
(This operation controls the fan speed at indoor unit side.)
The indoor fan (cross flow fan) is operated by the phase
control induction motor.
The fan rotates in 5 stages in MANUAL mode, and in 5
stages in AUTO mode, respectively. (Table 1)

 The fan speed broadly varies due
to position of the louver, etc.
The described value indicates one
under condition of inclining
downward blowing.
1) When setting the fan speed to L,
L+, M, M+ or H on the remote
controller, the operation is
performed with the constant
speed shown in Fig. 1.
2) When the fan speed mode is
manual and TA < 22°C and the
compressor stops, the fan speed
is controlled from W2
(20 seconds) to 0 rpm
(40 seconds).
3) When setting the fan speed to
AUTO on the remote controller,
revolution of the fan motor is
controlled to the fan speed level
shown in Fig. 2 and Table 1
according to the setup tempera-
ture, room temperature, and heat
exchanger temperature.
4) When the fan speed mode is
AUTO and the compressor stops,
the fan speed is controlled from
W2 (20 seconds) to 0 rpm
(40 seconds).
