Message
"P1"
Atmospheric probe fault
"HA"
High temperature alarm
"LA"
Low temperature alarm
"EE"
Memory breakdown or fault
The alarm message is displayed until the alarm condition is re-established. All alarm messages are displayed
alternately with the atmospheric temperature except for "P1" which flashes. To reset the "EE" alarm and start
normal operation again, press on any key. The "rSt" message will be displayed for 3 seconds.
a. The EE alarm
The regulator includes an internal memory checking system. The "EE" alarm flashes when an internal memory fault
has been detected. In this case, the alarm output is activated.
b. Reestablishment of alarms
"P1" probe alarms (probe defect), "P2": they stop automatically 10 seconds after the probe has resumed normal
operation. Check the connections before putting back the probe.
"HA" and "LA" temperature alarms: they stop automatically when the regulator's temperature returns to normal
values or when defrosting starts.
