When an inverter anomaly occurs, the alarm BLOCKS the compressor. To re-start the
compressor, you need to reset the inverter.
are inconsistent, the alarm DOES NOT BLOCK the compressor. The compressor continues to work
with the pressures programmed on the control unit. The alarm stops only when the remote command
starts working correctly again.
"Temperature OFF" and "Temperature differential" for the time defined in the parameter "Alarms delay".
for the time defined in the parameter "Alarms delay"
the parameter "Alarm type" is set as the "alarm"(see Dryer menu paragraph), the alarm BLOCKS the
compressor, otherwise the compressor continues to work. To re-start the compressor, you need to
replace the probe.
