Each unit can be set for unit ON, unit OFF, or setback operation.

Set back operation is useful for reducing running costs
e.g. At a hotel with a 24-hour system
8:00~23:00 Cooling operation with set temperature at 26°C
23:00~8:00 Setback operation with 2 degrees of setback
As shown in the chart on the night, the set temperature rises 2 degrees
automatically during the setback operation. When the setback operation
ends, normal operation will begin.
