Intelli-Time® Clock

Intelli-Time products are pre-programmed with the correct time and date.
Intelli-Time technology instructs the time and date to set themselves. All you
need to do is select your Time Zone and Daylight Saving Time preferences. The
clock will then automatically set itself and change for Daylight Saving Time.

Set the Time, Date & Units

Press the “ ” button, located on the back of the display, to enter
SET MODE. Once in set mode, the preference you are currently setting will
blink on the display.

To adjust the currently selected (ashing) item, press and release the “ “ or
“ “ buttons (press and HOLD to fast adjust).

To save your adjustments, press and release the “ ” button again to adjust
the next preference. The preference set order is as follows:

TIME ZONE ( PST MST CST EST AST HAT AKT)
DST (Daylight Saving Time ON or OFF)*

CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
TEMPERATURE UNITS (ºF or ºC)
PRESSURE UNITS (inHg or hPa)

*If you live in an area that observes DST, DST should be set to ON, even if it is
not currently Daylight Saving Time.

You will automatically exit SET MODE if no buttons are pressed for 10 seconds.
Enter setup mode at any time by pressing the “ ” button.

Display Backlight Settings

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

When display is powered with the power adapter, backlight remains on at
100% brightness. Press the 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 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 and outdoor sensor are critical to the accuracy
and performance of this product.

Display Placement

Place the display in a dry area free of dirt and dust. Display
stands upright for tabletop use or is wall-mountable.

Outdoor Sensor Placement

Sensor must be placed outside to observe outdoor conditions.
Sensor is water resistant and is designed for general outdoor
use, however, to extend its life place the sensor in an area

l

1111

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 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.).

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.

humidity. Located in the top right corner of the screen, a date and time stamp
are shown for when each value was recorded. You will automatically exit

all-time records if no buttons are pressed for 5 seconds.
To manually clear an all-time LOW record, press and hold the “ ” button

Troubleshooting

Tull

Outdoor

temperature

is ashing or

showing dashes

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 sensor
when temperature is below -4ºF/-20ºC). Do not use heavy duty
or rechargeable batteries. NOTE: It may take a few minutes for
display and sensor to synchronize after batteries are replaced.

• Check that the power adapter is plugged into the display
and an electrical outlet.

• Check that the batteries are installed correctly. Batteries may
need to be replaced.

• Reset display by pressing the RESET button, located on the

back of the display. Date and time will need to be

entered after a reset.

Flashing of the outdoor temperature is generally an
indication of wireless interference.

1. Bring both the sensor and display indoors, side by
side and remove power adapter/batteries from each.

2. Make sure the A-B-C switch on both units match.

3. Reinstall batteries in outdoor sensor.

4. Reinstall power adapter/batteries in display.

5. Let the units sit within a couple feet of each other
for a few minutes to gain a strong connection.

• Weather Forecast icon predicts conditions for the next

12 to 24 hours, not current conditions.

• Has Learning Mode icon disappeared from the display?
Learning Mode must complete before forecast and pressure

Inaccurate forecast

Inaccurate

temperature

or humidity

will be accurate.

• Allow unit to run continuously for 33 days. Battery removal
or resetting the display will restart Learning Mode. After
14 days, forecast should be fairly accurate, however,
Learning Mode calibrates for a total of 33 days.

• 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).

Care & Maintenance

Display 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

Clean with a soft damp cloth. Do not use caustic cleaners or abrasives.

Calibration

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

1. To access calibration mode, press AND HOLD the “
buttons simultaneously for at least 5 seconds.

2. To adjust the currently selected (ashing) item, press and release the
“ “ or “ “ buttons to calibrate the data value higher or lower from the
actual reading.

3. 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 20 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.
