STARTING UP
Immediately after powering, the controller tart the en or
heating pha e; the di play how the me age "HEAt" with
the icon " " fla hing.
Later, during normal operation, the di play will how the CO
2
level detected.
The " " icon i alway on.
ON/OFF
By pre ing the key " ", if enabled, it i po ible to witch
the controller on and off ( ee tep 8 in the "In tallation"
paragraph).
BACKLIGHT
Pre ing any key activate the backlight of the di play which
will witch off automatically after approximately 30 econd .
TEST FUNCTION
To verify correct operation of the controller, pre and hold the
"TEST" key for more than 20 econd ; the "OUT 1" output
key will be activated and the di play will light up the " "
icon for approximately 30 econd and the me age in motion
"- - - -" will be hown to indicate that the te t i in progre .
Pre the key " " to exit the "TEST" function at any time.
ALARM THRESHOLD DISPLAY
During normal operation, by pre ing the "▲" or "▼" key ,
will how on the di play (for approximately 6 econd ) the CO

RESET
To re et the controller remove voltage from the device for a
few econd and then witch it back on again.
Note: the data et will not be re et; the device will ju t be
activated again.
OPERATION
In normal operation, the LCD di play the " " icon
and the concentration of CO
2
(in ppm) mea ured in the
environment in which it i in talled.
If the device detect a concentration of CO
2
that i
greater
than the value et in the u er parameter 'CO2t', the output
OUT1 will be activated. Activation of the output will be
indicated on the di play by the icon " ".
The output will be di abled if the concentration of CO
2
fall
below the value et in the u er parameter "CO2t" minu the
hy tere i value of the device.

FAULT CONDITION
The controller con tantly perform a diagno i of the internal
circuit to verify it correct operation.
Where a fault condition i detected, the di play will how the
'FAULT' icon and an indication of the type of fault detected
while the OUT1 output will be activated.
CALIBRATION:
The controller continuou ly perform a en or auto-calibration ,
ba ed on the mea urement of the la t 14 day , without
requiring the intervention of the operator.

ERROR MANAGEMENT
Sen or Fault
If the device detect an anomaly on the internal en or, the
di play will how the me age:
"SnEH" or "SnI2"
"SnEH": Fault
upper limit on the CO
2
Sen or.
Thi fault may be linked to environmental
condition : change the air in the environment and
wait a few hour .
If the fault per i t , replace the device.
"SnI2": Fault
communication with the CO
2
en or.
Thi fault can be re olved by re etting the device.
If the problem per i t , replace the device.
The e report will be pre ent until the fault i removed.
Internal memory fault
In the event that the device detect a data torage fault, the
di play will how the me age "SnE2" with the " " icon
fla hing.
Thi type of problem can be olved by re toring the device
default data, by acce ing the u er parameter 4 "dEFt" and
electing "dFon".
If the problem i re olved, it i po ible to manually re et all
the data to the value before re et.
Conver ely, if the fault per i t , replace the device.
USER PARAMETER SETTING
To adju t the u er parameter of the device, proceed a
follow :
1. Pre and hold for more than 20 econd the
key " ";
the di play will how the "PARAMETER" icon and the fir t
u er parameter " CO2t ".
2. Repeatedly pre the key " " to cyclically croll through
the u er parameter :

5. To et the u er parameter pre the key " ".again
6. To exit the elected u er parameter modification mode,
pre the key " ".
7. To exit programming of the u er parameter , pre the key
" " again or wait 30 econd without pre ing any key.
PARAMETER 1: CO2t
Setting thi parameter enable definition of the value of
