7. ALARM SIGNALLING

Mess. Cause
"P1"
Room probe failure
"HA" Maximum temperature alarm
"LA" Minimum temperature alarm
"EA" External alarm
"CA" Serious external alarm
"dA" Door Open
ALARM RECOVERY
Probe alarm "P1" starts some seconds after the fault in the related
probe; it automatically stops some seconds after the probe restarts
normal operation. Check connections before replacing the probe.
Temperature alarms "HA" and "LA" automatically stop as soon as
the temperature returns to normal values.
Alarms "EA" and "CA" (with iF=bA) recover as soon as the digital
input is disabled.
