3. Hot Start
When the heating operation starts, the indoor fan stops and the compressor run with a certain frequency.
This is to prevent the cold airflow from blowing.
If the piping temperature rises to 19 ℃, and the indoor fan speed and airflow direction varies with the indoor piping
temperature, the hot start control is completed.
13.3.2 Overload Protection Control

13.3.3 Demand Control
When the air-conditioner connected to Demand Response Enabling Devices (DRED), the power
consumption especially during peak hours could be controlled.
Three Demand response modes (DRM) are available
DRM1 = Compressor cut off
DRM2 = Operate at 50% of rated input power
DRM3 = Operate at 75% of rated input power
During DRM, the Power Indicator blinks (3 seconds ON and 0.5 seconds OFF)
