Fiddling with appliances
Got a Waterlogic cooler in office? Is it set to lousy +87 degrees and you prefer it hotter? Wait no more. Just press all buttons simultaneously for 5 sec and switch to setup mode. From there use two left buttons to scroll throught menu, rightmost button to cancel/return back, button next to it to accept changes. Now that it is set to 95 degrees it feels much nicer!
