TEMPERATURE SCALE (ºF or ºC)
BAROMETRIC PRESSURE SCALE (inHg or hPa)
If you live in an area that observes daylight saving time, DST should be set to ON, even if it is not currently Daylight Savings Time.
You will automatically exit SETUP MODE if no buttons are pressed for 10
ox seconds. Enter setup mode at any time by pressing the ” ” button.

Backlight Settings
This weather station’s color display features three different lighting settings: High (100%) brightness, Medium (60%) brightness, and Low (30%) brightness.

Using battery power alone, the backlight is available momentarily for 7 seconds by pressing the Momentary Backlight button.

When the display is powered with the power adapter, the backlight remains on at 100% brightness. Press the Momentary Backlight button once to dim to 60% brightness; press again to dim to 30%, press a 3rd time to enter “AUTO DIM” mode. AUTO DIM appears below the time.

AUTO DIM MODE: Automatically adjusts display brightness based on time of day & year.

MARCH 11- NOVEMBER 4| 6:00 a.m. – 9:00 p.m. = 100% brightness
9:01 p.m. – 5:59 a.m.= 30% brightness
NOVEMBER 5 – MARCH 10| 7:30 a.m. – 7:00 p.m.= 100% brightness
7:01 p.m. – 7:29 a.m. = 30% brightness

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

Display Unit Placement
Place 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 Placement
Sensors 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.).

devices

Setup is Complete
The 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.

OPERATION

Using the Weather Station

Learning 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 Forecast
AcuRite’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 Pressure
Subtle variations in barometric pressure greatly impact the weather. This weather center displays the current pressure and indicates the direction the pressure is trending (FALLING, STEADY, or RISING).
Humidity Level Indicator
The Humidity Level Indicator easily conveys a low or high indoor humidity level for your home and health: Learn more at http://www.acurite.com /humidity-health

High & Low Records
Today’s high and low records are displayed for the indoor and outdoor temperature and humidity. Today’s records automatically clear at 12:00 am- midnight every day. View today’s high or low records by pressing the “ ∧ ” or “ ∨ ” buttons. Press and release again to view current readings.
To manually clear all of today’s LOW recorded values, press and release the “ ∨ ” button to view low records, then press and HOLD the “ ∨ ” button for 2 seconds. Dashes will display to confirm you have cleared the LOW records.
To manually clear all of today’s HIGH recorded values, press and release the “ ∧ ” button to view high records, then press and HOLD the “ ∧ ” button for 2 seconds. Dashes will display to confirm you have cleared the HIGH records.

Troubleshooting

Problem	Possible Solution

No outdoor sensor retention
no 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 sensor to synchronize after batteries are replaced.
Outdoor temperature is flashing or showing 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. Make sure the A-B-C switch on both units matches.
3. Reinstall the battery in the outdoor sensor.
4. Reinstall the battery in the display unit.
5. Let the units sit within a couple of feet of each other for about 20 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 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 9).
• Make sure both units are positioned away from moisture sources (see page 9).
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.
The unit lost power or batteries were changed and the time is not correct| • The Intelli-Time battery needs to be replaced (see page 13). Once the new battery is installed, the time and date will need to be set manually.

Calibration
The indoor/outdoor temperature and humidity readings, and barometric pressure can be calibrated on the display unit to improve accuracy. Calibration can improve accuracy when sensor placement or environmental factors impact the data accuracy.

To access calibration mode, press AND HOLD the “ ∧ “, “ “, and “ ∨ ” buttons simultaneously for at least 5 seconds.
To adjust the currently selected (flashing) item, press and release the “ ∧ ” or “ ∨ ” buttons to calibrate the data value higher or lower from the actual reading.
To save your adjustments, press and release the ” ” button to adjust the next preference. The ” ” icon will remain illuminated next to calibrated values.

The preference set order is as follows:

OUTDOOR TEMPERATURE
OUTDOOR HUMIDITY
INDOOR TEMPERATURE
INDOOR HUMIDITY
BAROMETRIC PRESSURE (must be set to MANUAL mode to calibrate)*

*To change from AUTO to MANUAL pressure mode and vice versa, press
AND HOLD the “ ” button for at least 10 seconds. The display indicates the current pressure mode selected,”AUTO” or “MANUAL”. After 5 seconds of inactivity, the display will save the adjustments and exit calibration mode. Note: Calibrations will be erased if the display is reset or if batteries are removed and the power adapter is unplugged.

Care & Maintenance

Display Unit Care
Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives. Keep away from dust, dirt and moisture. Clean ventilation ports regularly with a gentle puff of air.
Outdoor Sensor Care
