Operation flow and applicable data, etc.
<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, respec-
tively. (Table 1)

L- : Low–
UL : Ultra Low
SUL : Super Ultra Low
* 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 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.
