sent. Moreover, some events are sent with a ca. 2-minute delay or immediately.
For details, see the technical data "Frequency of transmission".
The room device stops transmitting if the energy store is not charged sufficiently
and/or the battery is empty.
100% functionality cannot be guaranteed under all circumstances. There are
simply too many possible sources of interference, both legal and illegal, impacting
range tremendously. This includes radio applications using the same frequency for
transmission, e.g. other control systems with wireless connection. In addition,
reflection based on room design or interior décor impacts signal quality and
transmission security.

14.2 Lighting conditions at mounting location
This section refers to room units equipped with solar cells. The data
provided below is based on QAX9x.4 room units.
For guaranteed operation (without battery), at least 200 Lux illuminance must be
present for at least 3 to 4 hours daily. Avoid direct exposure to the sun, as this
results in fault temperature readings. Avoid also shading by furniture as well as
mounting in wall recesses without sufficient lighting.
Startup time at empty energy store:
Approx. 1 min. at 400 lx
Illumination time required to charge the empty energy
store for 14 hours operation in total darkness:
Approx. 6 h at 400 lx 1), 2)
Illumination time to recharge a working energy store for
14 hours operation in total darkness:
Approx. 2 h at 200 lx 1), 2)
Maximum operating time at 100% charge and total
darkness:
Approx. 4 days
1) Sending a radio signal ca. every 15 minutes (average).
2) Typical value depending on prior charging of energy cell.
As brightness is hard to evaluate, we recommend control measurements using a
device to measure illuminance.
