Note:
If a parameter value is negative, LED3 circularly displays the negative code "nE‖ and the numeric value
every one second. For example, for -30C, LED3 alternately displays ―nE‖ for one second and then ―30‖
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 115C. If "nE", "00", and "28" are alternately displayed, it indicates -28C.
If a parameter is invalid for the unit, ―00‖ is displayed.
If no button operations are performed on the master unit for five minutes, the function setting
automatically quits and the unit restores the current status.
