Automated window coverings:
If you have automated window coverings that are sensor or timer driven, program the controller according to its capabilities.
Sensor operation: if your controller is able to automatically open and close at sunrise or sunset, use that automatic function.
Timer operation: set your controller to operate the window coverings at clock times close to the average sunrise and sunset time over the season instead (these times are listed above). Reprogram at the start of the heating season and the cooling season indicated for your LGA, OR at the beginning of April and October if your climate needs heating or cooling all year and your controller does not automatically adjust for sunrise/sunset at your location.
If your controller can use additional weather service or sensor inputs to control the window coverings, make sure that they will automatically close on hot sunny days in the heating season to avoid your home overheating.
Periodically check that your window coverings are operating as expected.
