*The evaporation temperature area changes depending on the maximum required level of each indoor unit as
shown in the right figure.
*C area is regarded as B area for 6 minutes after compressor starts.
*When the system operates in a minimum capacity, the system will continue operating for at least 6 minutes if the
evaporation temperature area is C area.
*The evaporation temperature is not adjusted while specially controlling defrosting and the oil recovery, etc.
