Through the
i.dS
parameter is possible to set the variable
normally displayed:
Pt
Measure of the
temperature
Probe;
Ph
Measure of the
humidity
Probe;
St
Set Point of the temperature control;
Sh
Set Point of the humidity control;
th
The temperature and humidity measures alternated
every 10 s;
tt
The temperature and the
t.of
timer decreasing count-
ing alternated every 10 s;
3U
The temperature, humidity and the
t.of
timer decreas-
ing counting alternated every 10 s;
of
Numerical display switched OFF.
The normally displayed value is established by parameter
i.dS
, but, repeatedly pressing and releasing key, it is
possible to sequentially display all the measurement and
operating variables. The display alternately shows the code
that identifies the variable and its value. The variables that
can be displayed are:
t
Temperature probe measurement;
h
Humidity probe measurement;
t.of
Countdown to the next activation of the auxiliary output
configured as
o.Fo
=
2
(only if the timer is enabled);
Lt
Minimum stored Pr1 temperature;
Ht
Maximum stored Pr1 temperature.
The system exits the variable display mode after 15 s from
the last key pressure.

Digital Input Configuration
The digital input function is defined using the
i.Fi
parameter
and the action is delayed for the time programmed with pa-
rameter
i.ti
. The
i.Fi
parameter can be configured for the
following functions:
0
Digital Input not active;
1
External alarm signalling via NO contact: closing the digi-
tal input (and after the
i.ti
time) the alarm is activated
and the instrument alternately shows on the display the
label
AL
and the variable set at parameter
i.dS
;
2
External alarm signalling with deactivation of all control
outputs via NO contact: closing the digital input (and after
the
i.ti
time) all the control outputs are disabled, the alarm
is activated and the instrument alternately shows on the
display the label
AL
and the variable set at parameter
i.dS
;
3
Instrument Switch ON/OFF (ON/Stand-by) of instrument
via NO contact: closing the digital input (and after the
i.ti
time) the instrument is switched
ON
while it is placed in
Stand-by
when the digital input is open;
4 AUX
auxiliary output remote control with NO contact:
when the input is closed (and after the
i.ti
time), the
auxiliary output is activated as described in the operating
modes of the auxiliary output;
5
Door opening signalling via NO contact: when the input
closes (and after the
i.ti
time) the instrument alternately
displays
oP
and the variable established with
i.dS
. With this
operating mode, the action of the digital input also activates
the time that can be set in parameter
A.oA
after which the
alarm is activated to signal that the door has remained open;
-1
,
-2
,
-3
,
-4
,
-5
These functions are like those just described, but work
with a reversed logic as the contact is NC.

Outputs and Buzzer Configuration
The instrument outputs can be configured by the relative pa-
rameters
o.o1
,
o.o2
and
o.o3
. The outputs can be configured
for the following functions:
ot
To manage the temperature control device. In the
case of neutral zone control (
r.HC
=
nr
) for the control
of the cooling control device;
rh
To manage the humidity control device. In the case of
neutral zone control (
r.ud
=
nr
) for the control of the
dehumidification control device;
HE
To manage the heating control device in case of neu-
tral zone control (
r.HC
=
nr
);
hu
To manage the humidification control device in case of
neutral zone control (
r.ud
=
nr
);
Au
To control the auxiliary device;
At
To control a silenceable alarm device through a con-
tact that is NA and closed when the alarm sounds;
AL
To control an alarm that cannot be silenced through a
contact that is NA and closed when the alarm sounds;
-t
To control a silenceable alarm device through a con-
tact that is NC and open when the alarm sounds;
-L
To control an alarm that cannot be silenced through a
contact that is NC and open when the alarm sounds;
on
Output ON when the instrument is in ON state. The
output is active when the instrument in ON and not
active when the instrument is in Stand-by mode. This
mode can be used to control shop lights, non-misting
resistances or other utilities;
L1
To manage a light device through the keys / or /
Aux
when correctly configured (
t.UF
or
t.Fb
= 4).
This output can be activated and deactivated even
when the instrument is placed in Stand-by;
of
Disabled output.
The function carried by for
Aux
output (
o.o1
,
o.o2
,
o.o3
=
Au
)
is defined by the parameter
o.Fo
and the function is condi-
tioned by the time set with parameters
o.tn
and
o.tf
.
Using the
o.tu
parameter is possible to establish whether the
scale of the
o.tF
parameter should be in
hours and minutes
(
H
) or in
minutes and seconds
(
n
).
o.Fo
can be configured for the following functions:
of
No function;
1.
Activation by the key / , /
Aux
or by Digital Input with
contact NO: the output is activated pressing a key
/ or /
Aux
suitably configured (
t.UF
or
t.Fb
=
1
) or
via the digital input (
i.Fi
=
4
). These commands have
a bi-stable function (toggle), which means that when
first pressed, the output is activated while the second is
disabled. In this mode, the
Aux
output can be turned
OFF automatically after a certain time that can be set ON
the parameter
o.tn
. With
o.tn
=
of
the output is activated
and deactivated only manually, using a key , , or via
the digital input. When
o.tn
=
time
, once activated the
output is turned OFF automatically after the
o.tn
time;
2.
Independent twin timer. The
Aux
output is activated
when the instrument is turned ON for the time
o.tn
then
it is deactivated for the time
o.tF
and so on. The
o.Fo
=
2
mode also provides a timer enabling/disabling function.
This function allows the user to manually disable/enable
the timer by pressing the /
Tm
key for 5 s. The flashing
Tm
LED indicates thet the timer is enabled. If
o.Fo
=
2
,
the first time the timer is switched ON, it is always enabled
and can be disabled/re-enabled using the /
Tm
key.
When the instrument is turned OFF and the next time it is
