※
The symbol ○ indicates is output signal, and the symbol × indicates is not output signal.
※
Operation and alarm signals will be indicated for each occurrence of each alarm.
※
If an error condition occurs such that the operation signal is continuously output, and if another error
also occurs that would shut down the compressor, then the operation signal will be cut off even if the
initial error continues.
※"Alternate display" in the Display column indicates that the water temperature measurement and the
alarm numbers are displayed in turn. "Blinking” indicates that the relevant alarm number blinks.
※
E14 only outputs a signal when the parameter F1 is set to "0" (the default setting.)
