I am in hotel H10 in Berlin, one of the
places with a keycard slot to control power on in the room.
At bedtime we located the switch for the entrance light, and turned it off - however, it now seems to have been a mains switch for the room, as the ac is now off.
Help - how can I get the ac back without the
light? Not currently able to experiment a
whole lot as my companion is asleep :-( But
for me - too hot.

Any suggestions?

Thanks,
DanishFlyer
