Congratulations on purchasing your new STEINEL sensor
and thank you for the confidence you have shown in us.
You have chosen a highquality product that has been
manufactured, tested and
packed with the greatest care.
Safety Precautions
Disconnect the power sup-
ply before attempting any
work on the sensor!
During installation, the
electric power cable to be
connected must be dead.
Therefore, switch 'OFF' the
power first and use a volt-

applicable national wiring
regulations and electrical
operating conditions (VDE
0100).
Installation/Wiring
The sensor is only intended
for concealed, indoor installation in ceilings (apart from
the COM 1 AP - surfacemounted - option). A clamping-type ceiling adapter or
surface-mounting adapter is
not included. Sensor and
load module come ready assembled and must be
plugged together after fitting
the load module and setting
the potentiometers/dip
switches. The sensor module
must now be locked in place
with the catch mechanism
, using a screwdriver if
necessary.
Installation site: Do not fit
the unit inside shelf units or
behind curtains and similar
covers so that the room's
normal convection air can
reach the air-quality sensor
without obstruction.

How It Works / Basic Function
The Air Control Signal air quality
sensor described below measures the concentration of carbon dioxide (CO
2) in room air by
means of an optical two-channel measurement system.
The CO
2 air quality sensor uses
an LED "traffic light" display
(green, amber, red) to indicate
when the quality of room air
rises above or falls below internally selected threshold
values. On red, a short acoustic
warning signal additionally
warns every 5 minutes.
The Air Control Signal air quality
sensor also provides a floating
switching output for connecting
an automatic ventilation system.
'ON'
Ventilation is switched
in
the amber range and only
'
switches
OFF' again when the
green LED shows.
However, the Air Control Signal
air quality sensor is not intended for use as a measuring
device or as part of a gas warning or other safety system. The
sensor is designed for operation
in dry rooms at a temperature of
5°C to +40°C.
All work, such as assembly
work, installation and testing,
must be carried out by skilled
personnel.

Electrical Installation/Automatic Mode
In selecting the wiring leads, it
is important to meet the wiring
regulations laid down in VDE
0100 (see Safety Precautions on
page 4). The following applies
to wiring presence detectors:
According to section 6 of
VDE0100 520, a multiple-core
lead containing both the mains
voltage leads and the control
leads (e.g. NYM 5 x 1.52) may
be used for wiring between the
sensor and electronic ballast.
The mains connection cable
must be no greater than 10 mm
in diameter. The clamping range
of the mains terminal is designed for a maximum of
2 x 1.5 mm
2
or 1 x 2.5 mm2.
