Operation of GS 41.10 knx
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

ASSEMBLY
Assembly
Disconnect device from power supply for wiring and installation
purposes! Check power supply is disconnected!
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 gets inside of the device.
 After initial startup, the device requires up to 5 minutes until the first correct
measurement is possible
STEP 1: Open the device with a small screw driver by pushing in the
lever at the bottom of the housing and gently remove the front cover.
STEP 2: Fix the rear cover, either directly to the wall or on a flush-mounting box
(see installation notes)
STEP 3: After wiring, press the “learn button” to set the device into programming
mode (this can be done at a later time as well)
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.
