RD ADA1
CARBON DIOXIDE CONTROLLER (CO
- Information, on the LCD display, of the level of CO
- Equipped with a voltage-free contact output
- Test function to ensure correct operation of the controller
- Option to change the alarm thresholds
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
level detected.
The " " icon is always on.
LEVEL
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
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 "
and the concentration of CO
2
environment in which it is installed.
If the device detects a concentration of CO
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
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.

ERROR MANAGEMENT
Sensor Fault
If the device detects an anomaly on the internal sensor, the
display will show the message:
2
"SnEH":
"SnI2":
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 "
TEST "
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 "
