Analogue Outputs (depending on model)
The measurement results of the device can be
negatively influenced by external factors. Possible
sources of interference are:
■ Draught and air movement:
e.g. through windows, doors, convection, heating and
people
■ Warming and cooling:
e.g. sunlight or mounting on an outside wall
■ Heat sources: close to installed electrical consumers
e.g. dimmers
■ Vibrations or shocks, which the unites are or
were subjected to
■ Pollution due to colors, wallpaper paste, dust
e.g. at renovation work
■ Organic solvents or their vapours:
e.g. detergents
■ Plasticizers from stickers and packaging:
e.g. bubble wrap or polystyrene
The device is not intended for use of unauthorized
constructional alterations, repairs and security relevant tasks
The device is not intended for use in outdoor areas and
wet rooms
The device is not qualified for security relevant tasks The
controlling of the device is only for the observation and
regulation of the air quality
The inappropriate use of the device can cause damage to
property and persons
The device has to be disposed in an environmentally
friendly manner according to the current electrical codes!

Attention! You have to check and consider the safety instructions above!
This device is suitable for wall mounting or for mounting on a flush-mounting box.
The device should not be exposed to dusty environment.
Ensure that no dust get inside of this device.
After initial startup, the device requires up to 5 minutes until the first correct measurement is possible
STEP 1: Open the device at the bottom and remove the front cover.
STEP 2: Mount the rear cover to the wall or on a flush-mounting box
STEP 3: Connect the RS 485 Modbus serial cable and configure device according to the project definition.
Afterwards connect the power supply
STEP 4: After completing the installation the front cover must be reattached
Installation note: Make sure that no wires are pinched or squeezed when installing the cover. The mounting of the device on a flush-mounting box is recommended for easier handling and wiring.
Power / Status LED: Green: In operation / Power on
Flashing green: False / faulty configuration (DIP-switches)
Red: Active bus communication
