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