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.

In starting
• Until 12 minutes passed after operation start
• When 12 to 25 minutes passed after operation
start and room temp. is 3°C or lower than set temp.
• Room temp. < Set temp. –4°C
In stability
• When 12 to 25 minutes passed after operation start
and room temp. is higher than (set temp. –3°C)
• When 25 minutes or more passed after operation start
• Room temp. ≥ Set temp. –3.5°C
5) In order to prevent Cold draft when
compressor step during heating
operation. Then louver will move to
upper position and fan speed will
reduce or off.

3) Min air flow rate is controlled by
temperature of the indoor heat
exchanger (Tc) as shown in Fig. 4
for prevent high temperature of heat
exchanger.
4) Cold draft prevention, the fan speed
is controlled by temperature of the
indoor heat exchanger (Tc) as shown
in Fig. 6 for keep warm temperature
of air flow.
