THEBEN LUNA 133 KNX User manual

Brand: THEBEN

Model: LUNA 133 KNX

Type: User manual

THEBEN LUNA 133 KNX is a compact KNX brightness sensor that precisely measures ambient light levels and transmits the data via KNX. With its wide measuring range of 1 to 100,000 lux and a detection angle of ±60° horizontal and -35° to +66.5° vertical, it offers comprehensive coverage. The device can be easily configured using ETS software, allowing you to set parameters such as the brightness threshold for sending updates and the cyclic transmission interval.

3.3.2 Object description

• Object 0 "Brightness value"

Sends the current brightness value either if there is a change in brightness and/or

cyclically depending on the configuration.

Note:

As a result of the restrictions due to EIS5, some values are rounded up or

down, e.g. the value 10000 Lux can be displayed as either 9999.36 ($4FA1) or

10004.48 ($4FA2).

Only send cyclically (if

enabled)

Send, if the value has changed

by 10%, 20%, 30% or 50%

since last sent; however, if a

change of 10% equals to a

change in brightness of < 1 lx,

then values are sent from 1 lx

onwards.
