Each compressor element is protected by a PT 1000 sensor (6) in the outlet pipe. The sensor is
connected to the electronic regulator.
When the maximum temperature is exceeded, the compressor element is stopped during 2
minutes before it can restart. If this happens 2 times within a time span of 2 hours, the element
will be stopped during 10 minutes. If the compressor element stops a third time within the 2 hours
time span, the element will be shut down and must be reset manually.
