13.5 Cooling overload control (Cool)
This control detect outdoor pipe temperature and perform the compressor frequency restriction during cooling
operation.
The compressor will be stopped to avoid compressor overloading.
13.6 Heating overload control (Heat)
This control detect indoor pipe temperature and perform the compressor frequency restriction during heating
operation.
This control detect outdoor ambient temperature and perform the fan speed adjustment during heating operation.
The compressor will be stopped to avoid compressor overloading.
