- Out of direct sunlight to avoid artificially high temperature readings.
- Protected from direct precipitation.
- Within 330 feet (100 meters) of the main alarm clock unit.
- Away from large metallic objects or thick walls that could interfere with the wireless signal.
The sensor has an integrated hanger for easy mounting.
4. Intelli-Time Technology
The AcuRite 13020 features Intelli-Time technology, which automatically sets the time and date upon initial power-up. It also automatically adjusts for Daylight Saving Time. Ensure your time zone is correctly set if needed (refer to Operating Instructions for time zone adjustment).
