ALARM SIGNALLING
Message Cause
Outputs
“P1” Thermostat probe failure
Compressor and heating outputs off
“P2” Evaporator probe failure
Defrost and by time
“P3”
Humidity probe failure
Humidity regulation off
“HA”
High temperature alarm
Outputs unchanged
“LA”
Low temperature alarm
Outputs unchanged
“HHA” High humidity alarm
Outputs unchanged
“HLA” Low humidity alarm
Outputs unchanged
“dA”
Door switch alarm
Outputs depending on the odC parameter
“EAL” External alarm
Other outputs unchanged
“BAL” Serious external alarm
Outputs OFF
“PAL” Pressure
switch alarm
Outputs OFF
The alarm message is displayed until the alarm condition recoveries.
All the alarm messages are showed alternating with the room temperature except for the “
P1
” which is flashing. To reset the “EE” alarm and restart
the normal functioning press any key, the “
rSt
” message is displayed for about 3s.

ALARM RECOVERY
Probe alarms
: “
P1
” (probe1 faulty), “
P2
”, “
P3
”; they automatically stop 10s after the probe restarts normal operation. Check connections before
replacing the probe.
Temperature alarms
“
HA
” and “
LA
” automatically stop as soon as the thermostat temperature returns to normal values or when the defrost starts.
Humidity alarms
“
HHA
” and “
LHA
” automatically stop as soon as the humidity returns to normal values.
Door switch alarm
“
dA
” stop as soon as the door is closed.
External alarms
“
EAL
”, “
BAL
” stop as soon as the external digital input is disabled
Pressure switch alarm
“
PAL” alarm is recovered by switching OFF the instrument
