LOW PRESSURE PRE-ALARM
The parameter PROT_5 defines the minimum evaporation pressure/temperature value in normal operation.
When the evaporation pressure/temperature exceeds the value specified by PROT_5 , compressor stages
are shutdown in turn with a time interval defined by the parameter TEMP_12 . The deactivation of the
compressor stages ends when evaporation pressure/temperature falls below the differential PROT_6 .

SUCTION PROBE ERROR
A suction probe error occurs when the measured value is outside the probe's range. While this error exists,
as many compressor stages are activated as there are specified in the parameter
PROT_1 . A delay of 2
minutes is fixed from the detection of this error to the initiation of the function.
DISCHARGE PROBE ERROR
A discharge probe error occurs when the value to be measured is outside the probe's range. While this
error exists, as many fans are activated as there are specified by the parameter
PROT_2 .
AMBIENT AIR PROBE ERROR
An ambient air probe error occurs when the value to be measured is outside the probe's range. While this
error exists, floating condensation is deactivated and the condensation value becomes the value specified
in the parameter
COND_1 .
PREVENTIVE MAINTENANCE OF THE COMPRESSORS
This alarm is activated when one of the compressors exceeds the hours of operation defined in parameter
PROT_7 . Once preventive maintenance has been carried out, setting the compressor's timer for
accumulated hours of operation to zero is recommended to deactivate the alarm.
