8.1.4. Soft Dry Operation

8.1.4.1. Thermostat control

  • 

Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -2.5°C.

  • 

Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point.

8.1.5. Heating Operation

8.1.5.1. Thermostat control

  • 

Compressor is OFF when Intake Air Temperature - Internal Setting > +1.5°C.

  • 

Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF
point -0.5°C.

8.1.6. 

Automatic Operation

This mode can be set using remote control and the operation is decided by remote control setting temperature, 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.
