AUTO DIM MODE: Automatically adjusts display brightness based on time of day.6:00 a.m. – 9:00 p.m. = 100% brightness9:01 p.m. – 5:59 a.m.= 30% brightness

Placement for Maximum Accuracy

AcuRite sensors are sensitive to surrounding environmental conditions. Proper placement of both the display and the outdoor sensor is critical to the accuracy and performance of this product.

Display PlacementPlace the display in a dry area free of dirt and dust. Display stands upright for tabletop use or is wall-mountable.Outdoor Sensor PlacementSensors 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 (1 to 2 meters) 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 and outdoor sensors 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 (90 cm) away from electronic devices (TV, computer, microwave, radio, etc.).

Setup is CompleteThe sensor will now synchronize with the display. 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 Station

Learning ModeSelf-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.

Barometric PressureSubtle variations in barometric pressure greatly affect the weather. This weather station displays the current pressure with an indicator to show the direction the pressure is trending (FALLING or RISING).High & Low Records High and low records reflect the minimum and maximum temperature and humidity recorded since the unit was powered on, since the batteries were replaced, or since the records were manually reset (whichever was most recent).To view the LOW records, press and release the “ ” button. The low record indicator appears on the display next to the low records.To view the HIGH records, press and release the “ ” button. The high record indicator appears on the display next to the high records.To reset the LOW records, press AND HOLD the “ ” button while viewing the low records. Dashes will display to confirm all low records have been reset.To reset the HIGH records, press AND HOLD the “ ” button while viewing the high records. Dashes will display to confirm all high records have been reset.


Problem Possible Solution
No outdoor sensor reception no bars If the wireless signal indicator shows no bars:• Relocate the display 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 -4°F/-20°C). Do not use heavy-duty or rechargeable batteries. NOTE: It may take a few minutes for the display and sensor to synchronize after batteries are replaced.
Outdoor temperatureis flashing or showing dashes Flashing of the outdoor temperature is generally an indication of wireless interference.1. Bring both the sensor and display indoors and remove batteries/power adapter from each.2. Make sure the A-BC switches on both units match.3. Reinstall batteries in the outdoor sensor.4. Reinstall batteries/power adapter in the display.5. Let the units sit within a couple of feet of each other for a few minutes to gain a strong connection.
Inaccurate forecast • Weather Forecast icon predicts conditions for the next 12 to 24 hours, not current conditions.• Has the Learning Mode icon disappeared from the display? 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 will restart Learning Mode. After 14 days, the forecast should be fairly accurate, however, Learning Mode calibrates for a total of 33 days.
Inaccurate temperatureor humidity • Make sure both the display 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).
Display swoon not working • Check that the power adapter is plugged into the display and an electrical outlet.• Reset the display by pressing the reset button, located on the back of the display. The date and time will need to be entered after a reset.
