Astronomical clock

Short description

IDEC SmartRelay Base Module is between the time of sunrise (TR) and the time of sunset
(TS). IDEC SmartRelay automatically calculates these times based on the geographical
location, the settings for automatic summertime/wintertime conversion, and the current time
of the module.
