Operation flow and applicable data, etc.
<In heating operation>
Description
1) When setting the fan speed to L,
L+, M, M+, H or Quiet on the remote
controller
, the operation is per-
formed with the constant speed
shown in Fig. 3 and Table 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. 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.

compressor step during heating
operation. Then louver will move to
