9. ALARMS
9.1 Alarms table
When an alarm is activated a message identifying the alarm is displayed
on the control module. In the event of potentially dangerous alarms, the
control automatically deactivates the humidi er (disablement). For some
alarm events, an alarm relay is activated simultaneously with the signal
(see table).
If the cause of the alarm is no longer valid, the humidi er and alarm
relay output can be reset automatically or manually, according to the
type of problem, while the message displayed is deactivated manually
by pressing the reset-PRG button. If no longer active, the alarm status
continues to be indicated until the reset-PRG button is pressed.
Still active alarms can not be reset.
Unless you are in the programming phase, in the presence of an alarm
condition, the alarm LED starts to  ash and the display will show the alarm
code with an alphanumeric code. The message is displayed cyclically, for
a duration of two seconds, alternating with the measurement normally
displayed (if the measurement normally displayed corresponds to
a disconnected probe, the measurement is not displayed; this will
automatically return to the display if the probe is reconnected). In the
event of more than one alarm, the display indicates all the corresponding
codes in sequence, at two second intervals.
Example: room probe alarm E3.

The Ec alarm cannot be reset (high water conductivity).
In the event of the alarm CL (regular maintenance required), the alarm
can be reset only by resetting the hour counter; see Resetting the hour
counter (see chapter 4).
The alarm E1 may appear in two distinct cases:
1. Malfunctioning during parameter memory reading (typically
upon start-up)
The default parameters are reset simultaneously without being
stored in parameters memory (the user can edit the parameters
and reset the correct values). However, we recommend you use the
default parameter access procedure (see chapter 4);
2. Malfunctioning during parameter memory reading (typically
when pressing the PRG key)
Any changes made are cancelled; te parameters can be accessed,
the value can be modi ed and the memorization operation can be
repeated.
