9. Commissioning

a) Inserting Batteries in the Outdoor Sensor
Open the battery compartment (18) on the bottom of the outdoor sensor by turning out the two screws of the battery
compartment lid and taking off the battery compartment lid.
Insert four type AA/mignon batteries with correct polarity (observe plus/+ and minus/-).
Operation with rechargeable batteries is generally possible. However, the lower voltage (rechargeable
batteries = 1.2 V, batteries = 1.5 V) and the lower capacity of rechargeable batteries will decrease the
operating time.
Rechargeable batteries are also more cold-sensitive (e.g. in winter), which further reduces the operating
duration. We therefore recommend that you use high-quality alkaline batteries to ensure long and safe
operation.
If you want to use rechargeable batteries in spite of these limitations, use special NiMH rechargeable bat-
teries with a low self-discharge; otherwise, the rechargeable batteries will have to be replaced frequently.
Close the battery compartment again.
b) Mounting the Outdoor Sensor
Mount the outdoor sensor in the outdoor area in a suitable location.
The collection opening of the rain sensor must point upwards. Also observe that the collection opening is horizontal,
since the measured values will be influenced otherwise.
Observe the following information when selecting of the mounting site:
The mounting site must be exposed for wind speed and wind direction to be measured correctly. A mini-
mum distance to buildings of 10 metres is recommended.
Do not mount the outdoor sensor under or close to trees or bushes because dropping foliage may clog the
opening in the rain sensor.
The range between the transmitter in the outdoor sensor and the weather station is up to 100 m in a free
range (at a direct line of sight between transmitter/receiver).
The range that can actually be achieved, however, is much lower since there are walls, furniture, windows
or plants between the weather station and the outdoor sensor.
Another interference that strongly reduces range is proximity to electrical/electronic devices, cables or
metal parts. Another problem are reinforced concrete ceilings, metal-vaporised isolating glass windows or
other devices on the same transmission frequency.
Therefore, perform a function and reception test before attaching the outdoor sensor (and, e.g., drilling
holes for attachment dowels).
The outdoor sensor can be attached in different manners with various openings. For example, wall assembly is pos-
sible via suitable screws/dowels or mast attachment is possible with cable ties or pipe clamps/screws.
Depending on assembly site (e.g. to a carport), you may be able to use an L-shaped holder as well that is available
as accessory for SAT dishes.
