Placement for Maximum AccuracyAcuRite sensors are sensitive to surrounding environmental conditions. Proper placement of both the display unit and outdoor sensor are critical to the accuracy and performance of this product.

Display Unit PlacementPlace the display unit in a dry area free of dirt and dust.The display unit stands upright for tabletop use or is wall-mountable.Outdoor Sensor PlacementThe sensor must be placed outside to observe outdoor conditions.The sensor is water-resistant and is designed for general outdoor use, however, to extend its life place the sensor in an area protected from direct weather elements.Hang the sensor using the integrated hang holes or hanger, or by using string (not included) to hang it from a suitable location, like a well-covered tree branch. The best location is 4 to 8 feet above the ground with permanent shade and plenty of fresh air to circulate around the sensor.

Important Placement Guidelines

  • To ensure accurate temperature measurement, place units out of direct sunlight and away from any heat sources or vents.
  • Display unit and outdoor sensor must be within 330 ft (100 m) of each other.
  • To maximize wireless range, place units away from large metallic items, thick walls, metal surfaces, or other objects that may limit wireless communication.
  • To prevent wireless interference, place both units at least 3 ft (.9 m) away from electronic devices (TV, computer, microwave, radio, etc.).

Setup is CompleteThe sensor will now synchronize with the display unit. It may take a few minutes for synchronization to complete. Please refer to the troubleshooting section of this manual if anything appears to be functioning improperly.


Using the Weather StationLearning Mode

Self-Calibrating Forecasting uses a unique algorithm to analyze changes in pressure over a time period (called Learning Mode) to determine your altitude.After 14 days, the Learning Mode icon disappears from the display screen. At this point, the self-calibrated pressure is tuned in to your location and the unit is ready for superior weather prediction.Weather ForecastAcuRite’s patented Self-Calibrating Forecasting provides your personal forecast of weather conditions for the next 12 to 24 hours by collecting data from the sensor in your backyard. It generates a forecast with pinpoint accuracy – personalized for your exact location.

Problem  Possible Solution 
No outdoor sensor receptionno bars If the wireless signal indicator shows no bars:• Relocate the display unit and/or the outdoor sensor.The units must be within 330 ft (100 m) of each other.• Make sure both units are placed at least 3 feet (.9 m) away from electronics that may interfere with the wireless communication (such as TVs, microwaves,computers, etc).• Use standard alkaline batteries (or lithium batteries in the sensor when the temperature is below -4ºF/-20ºC). Do not use heavy-duty or rechargeable batteries. NOTE: It may take up to 20 minutes for the display unit and sensorto synchronize after batteries are replaced.
Display screen not working • Check that the batteries are installed correctly.Batteries may need to be replaced.• Reset the display by pressing the reset button, located on the back of the display unit. The date and time will need to be entered after a reset.
Outdoor temperature is flashing orshowing dashes Flashing of the outdoor temperature is generally an indication of wireless interference.1. Bring both the sensor and display unit indoors and remove at least one battery from each.2. Reinstall the battery in the outdoor sensor.3. Reinstall the battery in the display unit.4. Let the units sit within a couple of feet of each other for about 20 minutes to gain a strong connection.
Inaccurate forecast The Weather Forecast icon predicts conditions for the next 12 to 24 hours, not current conditions.• Has the Learning Mode icon disappeared from the display unit? Learning Mode must complete before forecast and pressure will be accurate.• Allow the unit to run continuously for 33 days. Battery removal or resetting the display unit will restart Learning Mode. After 14 days, the forecast should be fairly accurate, however, Learning Mode calibrates for a total of 33 days.
Inaccurate temperature or humidity Make sure both the display unit and sensor are placed out of direct sunlight and away from any heat sources or vents (see page 8).• Make sure both units are positioned away from moisture sources (see page 8).
The unit lost power or batteries werechanged and the time is not correct • The Intelli-Time battery needs to be replaced (see page 13). Once the new battery is installed, time and date will need to be set manually.
