Start-Up and Operation
The dryer temperature remains under the temperature defined in the parameter
"Temperature OFF" for the time defined in the parameter "Alarms delay"
When an anomaly occurs on the dryer temperature sensor (sensor short
circuited or open), if 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.
