Notes:
①If a parameter value is negative, LED3 will circularly display the negative code ―nE‖ and the
numeric value at every one second. For example, for -30°C, LED3 will alternately display ―nE‖ for
one second and then ―30‖ for another second.
②The discharge temperature and ambient temperature will be displayed as four-digit values,
circularly displaying the higher two digits and then the lower two digits. For example, if 01 and 15
are alternately displayed, it indicates 115°C. If nE, 00, 28 are alternately displayed, it indicates
-28°C.
③ 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 will automatically quit and the
unit will resumes to the current status.
