Powering THEBEN 1409201

[ergo14]

Hello,
I plan to buy Theben 1409201 weather station (alternatively the MDT one).

Can I power the station from the white/yellow wires of the KNX bus?
The variant says 24V but the datasheet says:

Operating voltage 15 – 34 V DC Operating voltage KNX Bus voltage, ≤10 mA.

So maybe its fine if I power from the KNX cable without dedicated external power supply?

I've found the answer in the documentation, there is a dip switch for KNX Aux power.
