13. Operation Control
13.1 Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operation mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operation mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature.
13.1.1 Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

This mode can be set using remote control and the operation is decided by remote control setting temperature,
remote control operation mode and indoor intake air temperature.
During operation mode judgment, indoor fan motor (with speed of Lo-) is running for 30 seconds to detect the
indoor intake air temperature.
Every 10 minutes, the indoor temperature is judged. For the 1st judgment
o If indoor intake temperature - remote control setting temperature 3.6°F, COOL mode is decided. o If -3.6°F indoor intake temperature - remote control setting temperature < 3.6°F, DRY mode is decided. o If indoor intake temperature - remote control setting temperature < -3.6°F , HEAT mode is decided.

There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by
vertical vanes).
Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat
exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control).

Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the
angles as stated above. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below. When the air conditioner is stopped using remote control, the vane will shift to close position.
Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and
the positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close position.

o Quiet operation start condition
When “Quiet” button at remote control is pressed.
Quiet LED illuminates.
o Quiet operation stop condition
When one of the following conditions is satisfied, quiet operation stops:
POWERFUL/QUIET button is pressed. Stop by OFF/ON button. OFF Timer activates. POWERFUL/QUIET button is pressed again.
When quiet operation is stopped, operation is shifted to normal operation with previous setting. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode. During quiet operation, if ON timer activates, quiet operation maintains. After off, when on back, quiet operation is not memorised.
Control contents
o Auto fan speed is change from normal setting to quiet setting of respective fan speed. This is to reduce
sound of Hi, Me, Lo for 3dB.
o Manual fan speed for quiet operation is -1 step from setting fan speed.

changed from normal setting to quiet setting of respective fan speed. This is to reduce sound of Hi, Me, Lo for 3dB.
o Fan speed manual
Manual fan speed for quiet operation is -1 step from setting fan speed.
13.8 Powerful Mode Operation
When the powerful mode is selected, the internal setting temperature will shift lower up to 3.6°F (for Cooling/Soft
Dry) or higher up to 6.3°F (for Heating) than remote control setting temperature for 20 minutes to achieve the setting temperature quickly.
13.9 Timer Control
13.9.1 ON Timer Control
ON Timer can be set using remote control, where the unit with timer set will start operation earlier than the setting
time. This is to provide a comfortable environment when reaching the set ON time.
60 minutes before the set ON time, indoor (at fan speed of Lo-) and outdoor fan motor start operation for 30
seconds to determine the indoor intake air temperature and outdoor air temperature in order to judge the operation starting time.
From the above judgment, the decided operation will start operation earlier than the set time as shown below.
