※The symbol ○ for signals indicates that a signal is output,and the symbol × , that no signal is
output.
※The operating signal and an alarm signal behaviors represent the cases where the respective alarm is
generated by itself.
※Even with an alarm that sustains a signal generation, the operating signal is suspended if other alarms
are generated in conjunction and the compressor shuts down.
※"Alternate display" in the Display column indicates that the water temperature measurement and the
alarm number are displayed in turn. "Blinking" indicates that the relevant alarm number blinks.
※E14 only outputs a signal when "0" (default) is selected for the F1 parameter.
