Why hour setting 11:00 PM is not possible for "free rule" and "fixed date" on Theben Timer?
Setting the hour to 11:00 PM for "free rule" and "fixed date" is not possible on Theben Timer because of software complexities related to the summer/winter changeover. To avoid this, set the summer/winter changeover to 10:00 PM or 12:00 AM.

Why summer/winter changeover does not work properly in Australia on Theben Timer?
The summer/winter changeover might not work correctly in Australia on your Theben Timer because the changeovers in the southern hemisphere are opposite to those in the northern hemisphere. To fix this, use the free rule and set a date from the first half of the year (e.g., March) for the summer/winter changeover and a date from the second half of the year (e.g., October) for the winter/summer changeover.
Why the two left-hand buttons do not work when OBELISK top2 is inserted in Theben SELEKTA 171 top2 RC?
