The maximum and minimum Humidity alarms can be disa-
bled setting
A.Hh
and

.
The intervention of the Humidity alarms therefore provides
for the lighting of the alarm
AL
LED, the activation of the
outputs configured with an alarm function, the activation of
the internal buzzer if configured and, if provided, the display
of the messages:
Hih
In the event of a high Humidity alarm;
Loh
In case of a low Humidity alarm.
5.8.3 External Alarm from Digital Input
The instrument can notify an alarm external to the instru-
ment activated by the digital input having a programmed
action
i.Fi
=
1
or
2
.
Simultaneously to the configured alarm signal (buzzer and/
or output), the instrument points out the alarm lighting up the
AL
LED and displaying the label
AL
alternated to the vari-
able set at parameter
i.dS
.
i.Fi
=
1
mode produces no action on the control outputs
while with
i.Fi
=
2
the control outputs are disabled at digital
input intervention.
5.8.4 Open Door Alarm
The instrument can notify an
Open door alarm
activated by
the digital input with the function programmed as
i.Fi
=
5
.
When the digital input is activated, the instrument shows the
label
oP
(door open) on the display, then, after the delay pro-
grammed at parameter
A.oA
, the instrument signals the alarm
via the activation of the configured alarm output (buzzer/ouput),
lighting up the
Al
LED while continues displaying the label
oP
.
5.9
function of Keys
/ and
/Aux
Two of the instrument keys, in addition to their normal func-
tions, can be configured to operate other commands.
The / key function can be defined by the parameter
t.UF
while the /Aux key function can be defined by the param-
eter
t.Fb
.
Both the parameters can be configured to perform the follow-
ing functions:
of
The key carries out no function;
1
Pressing the key for at least 1 s it is possible to enable/
disable the auxiliary output as explained in the Aux output
configuration parameter;
2
Pressing the key for at least 1 s it is possible to switch
the instrument from the ON status to Stand-by status and
vice versa;
3
Pressing the key for at least 1 s it is possible to enable/
disable an Autotuning cycle (in the case of PID control
and
r.At
=
3
);
4
Pressing the key for at least 1 s it is possible toenable/
disable th output configured as
L1
.
