*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.
*The evaporation temperature is not adjusted when there are one or more indoor units that select the test run.
If one or more indoor units are selected into test run, the system doesn't stop in all states except alarm appearing.
*The test run will finish automatically in about one hour.
