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

23:00~8:00 Setback operation with 4 degrees of setback
As shown in the chart on the right, the set temperature rises 4 degrees
automatically during the setback operation. When the setback operation
ends, normal operation will begin.
