4.3 Nnstalling weather station
The weather station records precipitation events such as rain or snow,
wind speed and direction, ambient brightness, dawn/dusk and temperature
and receives the radio time telegram. The weather station only has to be
connected as a network device; the 24 V DC power supply is provided via
the four-wire bus line.
Use the enclosed mounting hardware to install the weather station. Note
also the installation instructions for the weather station in the associated
installation and operating instructions.
Metal-clad buildings, domestic interference sources (unshielded household
appliances, television sets, computers), supply lines and metal objects such
as sheet metal enclosures must be at least 0.5 m away from the sensor.
Check the radio clock reception prior to final installation.
The weather station must be mounted in an upright position with a maximum
inclination of ±2°. The photodiodes must be at right angles to the building
facades being shaded. Please refer also to the information on sun control in
the “Commissioning/Setting instructions” document.
The information on the allocation of the photodiodes to the facades is
required for commissioning.
Install the weather station in an easily accessible location at the highest point
of the roof structure or conservatory. To avoid hindering accurate
wind evaluation, do not mount the device away from the wind.
For the system to function properly, precipitation must be able to hit the
sensor surface from any direction without interference.
The connecting line must be routed so that water cannot enter into the inside
of the device. Use a weather-proof (suitable for outdoor installation) line for
this, such as 4x AWG26C UL BK or A-2Y(L)2Y...ST III BD 2x2x0.8 mm.
The photodiode 1 “Dawn/dusk” controls the dawn/dusk control. The weather
station should therefore be positioned so that the photodiode cannot be
influenced at night by street or garden lighting or other external light sources
(e.g. flashlights).
