2) 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.
3) Louver-free stop control
When the louver-free stop has been selected with the indoor function of wired remote controller “
POSITION”, the
louver motor stops when it receives the stop signal from the remote controller. If the auto swing signal is received from
the remote controller, the auto swing will start from the position where it was before the stop.
Note (1) When the indoor function of wired remote controller “
POSITION” has been switched, switch also the remote control function “
POSITION” in the same way.
4) Individual flap (louver) control system
The individual flaps (louvers) for 4 directions can be controlled to swing within the ranges between upper limit and lower
limit selected with wired remote controller respectively.
For detail setting method, refer to
⑦
in page 21.
Note (1) This function is not able to be set with wireless remote controller or simple remote controller (RCH-E3)
(k) Compressor inching prevention control
1) 3-minute timer
When the compressor has been stopped by the thermostat, remote controller 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.
2) 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 motor
1) Drain motor (DM) is operated during the cooling or dehumidifying mode operations and simultaneously with the
compressor ON. The DM continues to operate for 5 minutes after the operation stop, anomalous stop, thermostat stop or
when it was switched from the cooling and dehumidifying operations to the fan or heating operation.

a) Control A
i) If the float switch detects any anomalous draining condition, the unit stops with the anomalous stop (displays
E9) and the drain pump starts. After detecting the anomalous condition, the drain motor continues to be ON.
ii) It keeps operating while the float switch is detecting the anomalous condition.
b) Control B
If the float switch detects any anomalous drain condition, the drain motor is turned ON for 5 minutes, and at 10
seconds after the drain motor OFF it checks the float switch. If it is normal, the unit is stopped under the normal
mode or, if there is any anomalous condition, E9 is displayed and the drain motor is turned ON. (The ON condition
is maintained during the drain detection.)
2) Drain motor (DM) interlock control
a) Start conditions
Depending on the function setting by the remote controller, the drain motor is turned ON under either one of the
following conditions.
i) During heating mode operation (Both the thermostat ON/OFF)
ii) During heating mode operation (Both the thermostat ON/OFF) + Fan operation
iii) Fan operation
b) End conditions
The drain motor is turned OFF 5 minutes after the stop of operations i) to iii) above.
