(Continued)
<In heating operation> (Heat pump model)
(This operation controls the fan speed at indoor unit side.)
The indoor fan (cross fl ow 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 2)
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. 3 and
Table 2.
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. 5 according to
the set temperature and room
temperature.
3) Min air fl ow rate is controlled by
temperature of the indoor heat
exchanger (Tc) as shown in
Fig. 4.
4) Cold draft prevention, the
fan speed is controlled by
temperature of the indoor heat
exchanger (Tc) as shown in
Fig. 6.
