Select the best compromise between Illuminance, ventilation locations and
aesthetic requirements.
Where possible, install room units opposite windows with the longest daylight
exposure.
Avoid recesses without sufficient daylight.
With regard to future room use: Select a mounting location where the room unit
is not shaded by users (e.g. by moving around furniture).

Whether illuminance on the wall is actually 200 lx, depends in large measure on
local conditions. We recommend conducting reference measurements using a
luxmeter. A device with battery backup can be used is illuminance is insufficient
(see Section 14.3).
Solar energy cells must be charged prior to commissioning (especially after
storage for long periods in darkness prior to initial installation). This occurs
automatically as soon as the solar cell is exposed to light.
The device is fully operational after 3 to 4 days if the initial charge is not enough.
The energy is now sufficient to ensure full functionality even after darkness (even
at night or on weekends for up to 90 hours).
