Characteristics
1.
Designated use
t
The sensor serves to detect carbon dioxide (CO
2
), relative humidity
and temperature in a variety of rooms (offices, schools, meeting
rooms etc). The CO
2
content of the air is a verifiable indicator of
the air quality in the living area. The higher the CO
2
content, the
poorer the air. The devices are suitable for use in a normal environ-
ment.
•The CO
2
gas makes up only approx. 0.034 %
of our fresh air and acts as an indicator for assessing the
air quality in a room.
• The concentration of 0.1 % (1000 ppm) is the limit value for
indoor rooms.
• The maximum concentration in a workplace is 5000 ppm.

Safety
The regulations and instructions in the ZVEI/ ZVEH Handbook must
be observed to ensure that the bus lines are installed and the units
are commissioned in a professional manner.
Tampering with or making modifications to the device will invali-
date the warranty.
• Do not use the sensor for safety related gas measurements!
• Only operate the sensor with extra-low voltage!
• Do not drop the sensor. Strong vibrations interfere with the
accurate measurement of CO
2
.
• Locate the sensor (for temperature measurement) on an
internal wall, at about eye level.
• Avoid drafts or heat emission.
• Do not not mount the sensor on a soft surface
as this will inhibit air exchange.
Thresholds of different readings

Description and function
The sensor has 2 LEDs that indicate the current CO
2
content of the
measured ambient air and the humidity.
• Temperature detection range: 0–40 °C
• Setting range thresholds: 500-2550 ppm
• “Physical value” object: 0–9999 ppm
• “Relative humidity” detection range: 1 %–100 %
• There are 3 independent thresholds of the readings for CO
2
and
relative humidity as well as a threshold for the temperature
reading.
• Exceeding or under-running the thresholds triggers a
response: Send priority. Switching, value.
• Every threshold has a disable object.
Danger of death through electric shock or fire!
Installation should only be carried out by pro-
fessional electrician!
