10. Operation Control
10.1 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.
10.1.1 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.

Capability resume to indoor unit after waiting for 3 minutes, if the Intake Air temperature - Internal setting
temperature > Capability supply OFF point.
10.4 Heating Operation
10.4.1 Thermostat control
Capability supply to indoor unit is OFF (Expansion valve closed) when Intake Air Temperature - Internal setting
temperature > 1.8°F.
During this condition, the indoor fan is stopped if compressor is ON.  Capability resume supply to indoor unit after waiting for 3 minutes, if the Intake Air Temperature - Internal setting
temperature < Capability supply OFF point.
21
10.4.2 Temperature Sampling Control
Temperature sampling is controlled by outdoor unit where room temperature for all power supply ON indoor unit
could be obtained.
When capability supply to the indoor unit is OFF and the compressor is ON during heating operation, the indoor
fan motor is stopped. During this condition, 15 seconds after sampling signal from outdoor unit is received, the indoor fan start operation at low fan speed.
However, within first 4 minutes of capability stopped supply to the indoor unit, even sampling signal is received,
the sampling control is cancelled.
10.5 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 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.
