This parameter is invalid for the
GMV5 series.
Note:
If a parameter value is negative, LED3 circularly displays the negative code "nE‖ and the numeric value

for another second.
The discharge temperature and environment temperature are displayed as four-digit values, circularly
displaying the higher two digits and the lower two digits. For example, if "01" and "15" are alternately
displayed, it indicates 115C. If "nE", "00", and "28" are alternately displayed, it indicates -28C.
If a parameter is invalid for the unit, ―00‖ is displayed.
