ALARM SIGNALS

Alarm signals;
Message Cause
EE Date or memory failure
P1 Probe failure
HA
Max. temp. alarm
LA Min. temp. alarm

ALARM RECOVERY

Probe alarm "P1" starts some seconds after
the fault in the related probe; it automati-
cally stops some seconds after the probe
restarts normal operation. Check connec-
tions before replacing the probe.
Temperature alarms "HA" and "LA" auto-
matically stop as soon as the thermostat
temperature returns to normal values and
when defrost starts.
Alarms "EA" and "CA" (with i1F=bAL) re-
cover as soon as the digital input is
disabled.
Alarm "CA" (with i1F=PAL) recovers only by
switching off and on the instrument.
