 Set point attainment status
NOTE: This function is valid only when function setting 96 is set to "01" (Primary unit) or "02"
(Secondary unit).
When the room temperature does not reach the set point at a room due to the lower cooling perfor-
mance caused by external factor such as the outdoor temperature change, signal is output to tell
the attainment status of set point.
