2. Indoor fan
motor control
Operation flow and applicable data, etc.
<In cooling operation>
The indoor fan motor is operated in 5 stages in MANUAL
mode (Fig.1) and 5 stages in AUTO mode (Fig. 2)
Table 1 shown the indoor fan speed and air flow rate of
each mode.
Description
* Symbols
UH : Ultra High
H : High
M+ :
M : Medium
L+ : Low+
L : Low
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.
