6.1
To start up the device, simply plug it into a socket outlet in the
indoor 230 V mains power supply. The device then runs a
self-test, which takes approximately 2 seconds. Following device
initialisation, the LED is tested: it lights up red, green and orange
for half a second each. If an error occurs, the LED will flash red.
The 15-minute sensor warm-up phase then follows,
during which time the device LED flashes green.
The warm-up phase can be aborted by pressing and then
releasing (within 4 seconds) the button. The warm-up phase
might be aborted, for example, to teach in an actuator to the
sensor immediately after start-up. In this case, before continuing
operation, the device should be restarted by disconnecting and
then reconnecting the power supply. To do this, simply unplug
the device from the socket for a few seconds.
6.2
The radio-controlled sensor for carbon dioxide automatically
measures and saves a reference value within 24 hours.
A reference value can also be calibrated manually at any time. To
do this, expose the sensor to fresh air, then perform calibration
as follows:
• Press and hold down the teach-in button (for more than 4
seconds). The device LED starts to slowly flash red.
• Press and release the button again (within 4 seconds) to
perform fresh air calibration. This is acknowledged by the
device LED turning green.
