ENGLISH
STARTING UP
Immediately after powering, the controller starts the sensor
heating phase; the display shows the message "
HEAt
" with
the icon "
" flashing.
Later, during normal operation, the display will show the CO
2
level detected.
The "
" icon is always on.
ON/OFF
By pressing the key " ", if enabled, it is possible to switch
the controller on and off (see step 8 in the "Installation"
paragraph).
BACKLIGHT
Pressing any keys activates the backlight of the display which
will switch off automatically after approximately 30 seconds.
TEST FUNCTION
To verify correct operation of the controller, press and hold the
"
TEST
" key for more than 20 seconds; the "
OUT 1
" output
key will be activated and the display will light up the "
"
icon for approximately 30 seconds and the message in motion
"- - - -" will be shown to indicate that the test is in progress.
Press the key " " to exit the "
TEST
" function at any time.
ALARM THRESHOLD DISPLAY
During normal operation, by pressing the "
▲
" or "
▼
" keys,
will show on the display (for approximately 6 seconds) the CO
2
threshold set.
RESET
To reset the controller remove voltage from the device for a
few seconds and then switch it back on again.
Note: the data set will not be reset; the device will just be
activated again.
OPERATION
In normal operation, the LCD displays the "
" icon
and the concentration of CO
2
(in ppm) measured in the
environment in which it is installed.
If the device detects a concentration of CO
2
that is
greater
than the value set in the user parameter 'CO2t', the output
OUT1 will be activated. Activation of the output will be
indicated on the display by the icon "
".
The output will be disabled if the concentration of CO
2
falls
below the value set in the user parameter "CO2t" minus the
hysteresis value of the device.

FAULT CONDITION
The controller constantly performs a diagnosis of the internal
circuit to verify its correct operation.
Where a fault condition is detected, the display will show the
'
FAULT
' icon and an indication of the type of fault detected
while the OUT1 output will be activated.
CALIBRATION:
The controller continuously performs a sensor auto-calibration ,
based on the measurements of the last 14 days, without
requiring the intervention of the operator.

Sensor Fault
If the device detects an anomaly on the internal sensor, the
display will show the message:
"
SnEH
" or "
SnI2
"
"
SnEH
":
Fault
upper limit on the CO
2
Sensor.
This fault may be linked to environmental
conditions: change the air in the environment and
wait a few hours.
If the fault persists, replace the device.
"SnI2
":
Fault
communication with the CO
2
sensor.
This fault can be resolved by resetting the device.
If the problem persists, replace the device.
These reports will be present until the fault is removed.
Internal memory fault
In the event that the device detects a data storage fault, the
display will show the message "
SnE2
" with the "
" icon
flashing.
This type of problem can be solved by restoring the device
default data, by accessing the user parameter 4 "
dEFt
" and
selecting "
dFon
".
If the problem is resolved, it is possible to manually reset all
the data to the value before reset.
Conversely, if the fault persists, replace the device.
USER PARAMETER SETTING
To adjust the user parameters of the device, proceed as
follows:
1.
Press and hold for more than 20 seconds the
key " ";
the display will show the "
PARAMETER
" icon and the first
user parameter "
CO2t
".
2.
Repeatedly press the key " " to cyclically scroll through
the user parameters:
"
CO2T
"
alarm threshold
"
T_LO
"
lower limit threshold
"
T_UP
"
upper limit threshold
"
dEFt
"
DEFAULT DATA Management
3.
Press the "
▲
" or "
▼
" key to modify the parameter
selected; the "
SET
" icon will flash
4.
Press the "
▲
" or "
▼
" key again to change the value;
each modification is stored automatically
.
5.
To set the user parameter press the key " ".again
6. To exit the selected user parameter modification mode,
press the key " ".
7. To exit programming of the user parameters, press the key
" " again or wait 30 seconds without pressing any key.
PARAMETER 1: CO2t
Setting this parameter enables definition of the value of
CO
2
beyond which the device enters the alarm phase and activating
the OUT1 output.
ATTENTION
The adjustment range is linked to the values set in the
T-LO and T-UP user parameters.
PARAMETER 2: T_LO
This parameter sets the value of the lower bound for the alarm
threshold adjustment, which can be set in the user parameter
"
CO
2
t
".
PARAMETER 3: T_UP
This parameter sets the value of the upper bound for the alarm
threshold adjustment, which can be set in the user parameter
"
CO
2
t
".

PARAMETER 4: dEFt
Using this parameter, by selecting the "

" data, it is
possible to restore, in the device, the default values set in the
factory.
Conversely, by setting "
no
" the stored data is maintained.
Note: resetting the DEFAULT data, new heating of the sensor
is activated.
