Data Sheet for Product

Mechanical design
The units have been designed for wall mounting. They are suited for use with most
types of commercially available recessed conduit boxes. The cables can be introduced
from the rear (concealed wiring) or from below or above (surface-run wires) through
knock-out openings.
The units consist of 2 major sections: Housing and base. Both snap together but can be
detached again. The base carries the connection terminals.
Disposal
The devices are considered electronics devices for disposal in terms of European Di-
rective 2012/19/EU and may not be disposed of as domestic waste.
• Dispose of the device via the channels provided for this purpose.
• Comply with all local and currently applicable laws and regulations.
Engineering notes
The permissible cable lengths are dependent on the type of controller with which the
sensor is used. They are specified in the Data Sheet of the relevant controller.
Mounting notes
Location: On an inner wall of the space to be heated or air conditioned. Not in re-
cesses, shelves, not behind curtains, not opposite or near heat sources.
The unit must not be exposed to direct solar radiation.
The end of the conduit at the sensor must be sealed to prevent false measurements
due to drafts through the conduit.
The permissible ambient conditions should be observed.
Installation Instructions are printed on the packaging.
