Setting up and Installation
• The installation site for the outdoor sensor should be chosen so that it is located in a place
that is protected from precipitation (e.g. under the eaves), otherwise the sensor will not be
able to measure the air temperature any longer.
Nor must the sensor be exposed to direct sunlight (faulty measurements due to sunlight
exposure).
• Keep a sufficient distance to metallic surfaces, cables, power outlets or electrical devices
since they reduce the radio range.
• By means of the hole for the wall mounting (6), the outdoor sensor can be hung for example
on a screw or hook.
• The outdoor sensor may also be used standing upright.
Take care that the outdoor sensor is placed so it does not stand in or under water
(e.g. during rainfall), since water may enter through the holes in the bottom. The
outdoor sensor must not overturn!
The outdoor sensor must not be operated in, or under water, since this will damage
it!
Transmission range
Under optimal conditions, the transmission range of the outdoor sensor’s radio signals is up
to 100 m. This is also often called the “free-field coverage”.
However, this ideal arrangement (e.g. weather station and outdoor sensor on a plain, even
meadow without trees, houses etc.) never exists in practice.
Normally, the weather station is installed in the house or the outdoor sensor for temperature
and air humidity is mounted on the exterior of the house next to a window.
Due to the different influences on the radio transmission, no specific range can be guaranteed.
However, trouble-free operation is usually possible in a detached house.
When the weather station does not receive any data from the outdoor sensor (despite new
batteries), reduce the distance between outdoor sensor and weather station; change the
installation site.
The range can sometimes be reduced considerably due to:
• Walls, reinforced concrete floors
• Coated/metallised insulated glass
• Vehicles
• Trees, bushes, earth, rocks
• Proximity to metal & conducting objects (e.g. radiators)
• Proximity to human bodies
• Broadband interference e.g. in residential areas (mobile phones, radio headphones, radio
loudspeakers, other weather stations etc.)
• Proximity to electrical motors, transformers, mains adapters, computers, cables, power
outlets or other electrical devices
Maintenance and Cleaning
The product is maintenance-free for you; you should never dismantle it (except for inserting/
replacing the batteries or rechargeable batteries as described in these operating instructions).
Use a clean, dry soft cloth to clean the outdoor sensor.
Do not apply excessive pressure on the display. This may lead to scratches or
display malfunctions.
Never use aggressive cleansing agents or other chemical solvents, since they can
damage the surface of the housing or even impair operation.
Do not point a garden hose or other irrigation system or a high-pressure cleaner at
the outdoor sensor.
