Important information prior to installation and commissioning

EN
Installation as a stationary controller
The DuoFern Environmental Sensor may only be used as a stationary installation, i.e.
only in an installed state and after completion of all installation and commissioning
operations and only in the intended environment.
Risk of short-circuits when installing in the rain
Do not open the DuoFern Environmental Sensor if water (rain) can penetrate into
it; even a few drops could damage the electronics. Ensure it is connected properly.
An incorrect connection can lead to destruction of the environmental sensor and the
control electronics.
Avoid damage during the installation
During installation, pay particular attention to ensure that the temperature sensor
(small printed circuit board on the underside of the housing) is not damaged. Also
ensure the connecting cable between the printed circuit board and rain sensor is not
torn off or kinked when connecting it.
Notes on radio systems
During planning, ensure that there is adequate radio reception. The range of radio
controls is limited by the statutory provisions for radio systems and by conditions at
the installation site (if the radio signal has to pass through walls and ceilings).
A minimum distance of 30 cm should be maintained between radio transmitters in
order not to impair the reception quality. Powerful local transmitters (e.g. radio head-
phones) transmitting in the same frequency band can interfere with the reception.
Dimensions and drilling templates
All the dimensioned drawings necessary for the installation can be found on page 46.
