Action
There may be an issue with the battery
in the board, please check the battery
and if it's not working change it.
Check also connections.
Contact the closest Climma service
center
Discharge pressure reading is more
then the allowed value therefore the
systems shuts off to keep the
compressor safe. Check the pressure
values registered in the log at the time
of the error.
Check the sea water pump and flow, as
there may be not enough flow thorugh
the sea water condenser.
the suction pressure reading is below
the safety levels. Please check the value
of the pressures and try to reset
manually the alarm.
If it does not stop, contact the closest
Climma service center.
There is a proble with one or more
probles. Please check the probes
connections. Try to reset manually the
alarm, then if it does not go away, shut
off the system, wait 1 minute, then try
to restart the system. If the error does
not go eway, contact the closest
Climma service center.
Superheat value is below the threshold
allowed, check and monitor the system.
Try to reset manually the alarm, then if
it does not go away, shut off the
system, wait 1 minute, then try to
restart the system. If the error does not
go eway, contact the closest Climma
service center.
The evaporating temperature of the
system is low, maybe there is not
enough refrigerant or the probe is
faulty. Try to reset manually the alarm,
then if it does not go away, shut off the
system, wait 1 minute, then try to
