12 Operation and Control
12.1. Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,
automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating 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.

12.1.1.
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.

Cooling Operation
12.1.2.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -1.5
°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point.
12.1.3.
Soft Dry Operation
12.1.3.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperate < -2.0
°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point.
12.1.4.
Heating Operation
12.1.4.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperate > +2.0
°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF
point.

12.1.5.
Automatic Operation
• This mode can be set using remote control and the operation is decided by remote control setting temperature, remote control
operation mode, indoor intake air temperature and outdoor air temperature.
• During operation mode judgment, indoor fan motor (with speed of Lo-) and outdoor fan motor are running for 30 seconds to
detect the indoor intake and outdoor air temperature. The operation mode is decided based on below chart.
Every 30 minutes, the indoor and outdoor temperature is judged. Based on remote control setting temperature, the value of T1 will
increase up to 10
increase up to 10
°C, T2 will decreased by 3°C and T3 will decreased up to 8°C.
The Auto Operation Mode shifting will take place whenever operation mode changed from Cooling/Soft Dry to Heating or vice
versa.

[Heating]
• According to indoor pipe temperature, automatic heating fan speed is determined as follows.
B. Feedback control
• Immediately after the fan motor started, feedback control is performed once every second.
• During fan motor on, if fan motor feedback 2550 rpm or < 50 rpm continue for 10 seconds, then fan motor error counter
increase, fan motor is then stop and restart. If the fan motor counter becomes 7 times, then H19 - fan motor error is detected.

12.2. Airflow Direction
1. There is one type of airflow, vertical airflow (directed by horizontal vane).
2. Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger
2. 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).
