<In heating operation> (Heat pump model)
(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 2)
(Fig. 3)
(Fig. 4)
(Fig. 5)
Cold draft preventive control
(Fig. 6)
Description
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 flow 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.
