F66 – Daylight Saving Time (DST) Mode
Use function F66 to enable or disable Daylight Saving Time (DST), and to schedule when
Local time enters and leaves DST. The factory setting for F66 is Manual (i.e., DST On). The
hour for entering/leaving DST is given in the 24-hour format. Entering/leaving DST can be
scheduled for any hour of the day, any day of the year. However, transitions scheduled
within 24 hours of the beginning/end of the year may not occur at the desired time. This
function also works for locations in the southern hemisphere, where DST spans the new
