Functional description
The yearly timer sets the output at a specific on-time, and
resets it at a specific off-time. The off-date identifies the day
on which the output is reset again. The first value identifies
the month, the second the day. For "MM" you can select a
placeholder (**), so that the on- and off-time is set for a
specific day each month.
