NOTE the message "Err" is displayed for failed programming. In this case turn the unit off and then on if you want to restart the download again or

remove the "Hot key" to abort the operation.

15. ALARM SIGNALLING

Message Cause

"P1"

Thermostat probe failure

"P2"

Evaporator probe failure

"P3"

Humidity probe failure

"HA"

High temperature alarm

"LA"

Low temperature alarm

"HHA"

High humidity alarm

"HLA"

Low humidity alarm

"dA"

Door switch alarm

"EAL"

External alarm

"BAL"

Serious external alarm

"PAL"

Pressure switch alarm

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.

15.1 SILENCING BUZZER

Once the alarm signal is detected the buzzer, if present, can be silenced by pressing any key.

15.2 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.
