4 General system information about
HomeMatic
This device is part of the HomeMatic home control system and
works with the bi-directional BidCoS
All devices are delivered in a standard configuration. The
functionality of the device can also be configured with a
programming device and software. The additional functions that can
be made available in this way and the supplementary
functions provided by the HomeMatic system when it is
combined with other components are described in the HomeMatic
WebUI Manual.
All current technical documents and updates are provided at www.
homematic.com.
5 General information about radio
operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possibility of interfer-
ence occurring.
Interference can also be caused by switching operations,
electrical motors or defective electric devices.
The range of transmission within buildings can differ greatly
from that available in the open air. Besides the transmitting
power and the reception characteristics of the receiver,
environmental influences such as humidity in the vicinity
and local structures also play an important role.
eQ-3 AG hereby declares that this device
complies with the essential requirements and other relevant regula-
tions of Directive 1999/5/EC.

Start-up/Operation

6.1

Device start-up

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 imme-
diately after start-up. In this case, before continuing operation, the
device should be restarted by disconnecting and then reconnect-
ing the power supply. To do this, simply unplug the device from the
socket for a few seconds.
6.2 Carbon dioxide reference value measurement
and calibration
The radio-controlled sensor for carbon dioxide automatically meas-
ures 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.
