(ii)
Automatic louver level setting during heating
At the hot start with the heating thermostat OFF, regardless whether the auto swing switch is operated or not (auto swing
or louver stop), the louver takes the level position (In order to prevent the cold start). The louver position display LCD
continues to show the display which has been shown before entering this control.
(iii)
Louver-free stop control
When the louver-free stop has been selected with the indoor function of wired remote control “
POSITION”, the
louver motor stops when it receives the stop signal from the remote control. If the auto swing signal is received from the
remote control, the auto swing will start from the position where it was before the stop.
Note (1) When the indoor function of wired remote control “
POSITION” has been switched, switch also the remote control function
“
POSITION” in the same way.
(k) Compressor inching prevention control
(i)
3-minute timer
When the compressor has been stopped by the thermostat, remote control operation switch or anomalous condition, its
restart will be inhibited for 3 minutes. However, the 3-minute timer is invalidated at the power on the electric power
source for the unit.
(ii)
3-minute forced operation timer
• Compressor will not stop for 3 minutes after the compressor ON. However, it stops immediately when the unit is
stopped by means of the ON/OFF switch or by when the thermister turned OFF the change of operation mode.
• If the thermostat is turned OFF during the forced operation control of heating compressor, the louver position (with the
auto swing) is returned to the level position.
Note (1) The compressor stops when it has entered the protective control.
(l)
Drain pump control
(i)
This control is operated when the inverter frequency is other than 0 Hz during the cooling operation and automatic
cooling and dehumidifying operations.
(ii)
Drain pump ON condition continues for 5 minutes even when it enters the OFF range according to (i) above after turning
the drain pump ON, and then stops. The 5-minute delay continues also in the event of anomalous stop.
(iii)
The drain pump is operated with the 5-minute delay operation when the compressor is changed from ON to OFF.
(iv)
Even in conditions other than the above (such as heating, fan, stop, cooling thermostat OFF), the drain pump control is
performed by the drain detection.
(v)
Following settings can be made using the indoor function setting of the wired remote control.

(m) Drain motor (DM) control
(i)
Drain detection switch is turned ON or OFF with the float switch (FS) and the timer.
[
＊
1]
Drain detection switch is turned “ON” when the float switch “Open” is detected for 3 seconds continuously in the
drain detectable space
.
[
＊
2]
Drain detection switch is turned “OFF” when the float switch “Close” is detected for 10 seconds continuously.
1) It detects always from 30 seconds after turning the power ON.
a) There is no detection of anomalous draining for 10 seconds after turning the drain pump OFF.
b) Turning the drain detection switch “ON” causes to turn ON the drain pump forcibly.
c) Turning the drain detection switch “OFF” releases the forced drain pump ON condition.
: Drain pump is run during cooling and dry.
: Drain pump is run during cooling, dry and heating.
: Drain pump is run during cooling, dry, heating and fan.
: Drain pump is run during cooling, dry and fan.
