3. Briefly press the operating button to select the correct function:
■ Controller function: The CO
turn red.
■ Sensor function: The CO
4. Press the operator button for 5 seconds to confirm the selection:
■ All LEDs on the right blink green 3 times.

Sensor The signal from
the device is the
measured value.
(In this case, 2V
corresponds to
400ppm and 10V to
2000ppm)
The controller that
ensures that the
level of CO
not become too high
is located in the
ventilation unit.
Controller A signal from the
device provides the
ventilation needed to
reach 1050ppm.
The ventilation unit
can be controlled via
the 0­10V input.
