The Acu-Rite 00787 Wireless Weather Forecast Station displays a wealth of information in its large, backlit, 3-line LCD panel. The top line is where you'll see an animated weather forecast icon along with a barometric pressure trend arrow. Displayed to the right of the forecast icon in vertical order are the time, a moon phase animation, and the month, date, and weekday. The top line is also where several clock-related function icons appear when active. The second line of the LCD panel displays the outdoor temperature and relative humidity from up to three locations, and the third line displays the indoor temperature and relative humidity. Trend arrows are displayed adjacent to all temperature and humidity values. Outdoor temperature data is transmitted to the 00787 main unit by the included 00911 remote sensor/transmitter, and the main unit can operate with up to three of these remotes. The 00911 has its own temperature and humidity display for local viewing, and you can select °F or °C for the display on both the 00787 and 00911 simply by pushing a button on each unit.

This compact wireless weather station has a minimum/maximum memory for all temperature and humidity readings, both indoor and from all remotes in use. Its integral Atomix^® radio controlled ("atomic") clock has dual daily alarms with snooze. The 00787 main unit is free-standing, while the 00911 remote can be wall-mounted or free-standing.

In addition to an animated weather forecast, the 00787 has an animated moon phase display that's a little different from most. The 00787 actually scrolls through eight different moon phases at a rate of one phase per second. When the current moon phase is reached, that phase remains displayed for 10 seconds (not 5 seconds as indicated in the manual), and then the scrolling continues. 

The 00787 also monitors and displays the indoor temperature and relative humidity and, as measured and reported by the included 00911 wireless sensor, the temperature at an outdoor or other remote location. Trend arrows are displayed with all temperature readings and the indoor humidity reading. Indoor humidity is displayed in %, and temperatures can be displayed in either °F or °C, as selected by a pushbutton on the side of the case. The 00787 has a total of seven control pushbuttons, six on the right side of the case and one on the back. There's also a SNOOZE/LIGHT bar on the top.

The integral memory in the 00787 records maximum and minimum indoor temperature and humidity values plus maximum and minimum outdoor temperature and humidity values for all remotes in use These are available for display at the push of the MIN/MAX button and remain displayed for about 5 seconds. Minimum and maximum temperatures and humidity are stored and updated until the memory is reset. To reset the memory, you press CLEAR with maximum values displayed and then again with minimum values displayed.

The 00787 forecast station uses the Acu-Rite 00911 remote sensor, which has its own temperature and humidity display for local viewing. One 00911 is included, and the 00787 actually works with up to three 00911s. Additional remote sensors are sold separately. The 00911 should be mounted in a sheltered location where direct precipitation cannot fall on it. Maximum transmission range of the 00911 is 100 feet (30 meters) in open space. Although this remote is splash-resistant, it is not waterproof. If multiple remotes are used, you can press the CH (channel) button to select the desired remote or to select an auto-scroll channel display.

Indoor temperature measuring range of the 00787 is +32°F to +122°F (0°C to +50°C). Outdoor/remote temperature measuring range is  -4°F to +122°F (-20°C to +50°C). If the 00911 remote will be used in sub-freezing temperatures, lithium AA batteries are recommended instead of alkaline. The display may fade, but the remote will continue measuring and sending temperature and humidity data. When the temperature warms back up, the display will return.

The clock in the 00787 is an atomic (radio controlled) clock that sets itself automatically and adjusts automatically for daylight saving time. This clock keeps perfect time by calibrating itself to 60kHz low-frequency AM radio signals containing time information supplied by the official U.S. atomic clock source in Boulder, Colorado. The signals are transmitted from radio station WWVB located in nearby Fort Collins. Both the atomic clock source and WWVB are operated by the National Institute of Standards and Technology, or NIST (a part of the U.S. Commerce Department).

Successful reception of the time-synchronization radio signal is indicated by a radio tower and waves icon just above seconds in the top line of the display. After synchronization occurs, you then select your continental U.S. time zone (EST, CST, MST, or PST). If you live in an area that does not observe daylight saving time (Arizona and parts of Indiana), you can manually disable the automatic DST changes.

Time on the 00787 can be displayed in 12-hour mode with PM when appropriate, or in 24-hour mode. The clock has two daily alarms, each of which sounds with a 2-minute crescendo pattern. Pressing the SNOOZE/LIGHT when an alarm is sounding turns off the alarm for a 5-minute snooze period. Pressing the SNOOZE/LIGHT bar at any time lights the green LED backlight for the LCD panel.

Calendar and moon phase information is pre-programmed from year 2000 through 2099 (default is 2002). The year is displayed only during manual setup, which is optional. Month and date are displayed digitally, and the weekday is indicated by a box around the day abbreviation. If you do set the clock manually, you'll need to set the time, year, month, and date. The weekday and moon phase update automatically.

The 00787 main unit is powered by two AA (1.5V) alkaline batteries, and the 00911 remote is powered by two AAA (1.5V) alkaline batteries. These are not included and must be obtained separately. Expected battery life is 1 year. If the 00911 remote will be used in sub-freezing temperatures, lithium AA batteries are recommended instead of alkaline. The display may fade, but the remote will continue measuring and sending temperature and humidity data. When the temperature warms back up, the display will return.

The 00787 main unit is designed for free-standing use only (even though its stand is removable). The 00911 remote comes with its own snap-on mounting bracket. This bracket has a keyhole slot for wall mounting and an integral fold-out stand for free-standing use. Acu-Rite even includes a screw on which to hang the 00911.

If you're looking for a fairly small wireless weather forecast station with lots of features, the Acu-Rite 00787 may fit your needs perfectly. Its forecast and moon phase display are animated. And not only can it display temperatures in °F or °C, it also has a min/max memory for indoor and all outdoor/remote temperatures and humidity. Plus, its incredibly accurate atomic clock has dual alarms and snooze. The 00787 is ideal for home or office. Use it to monitor the temperature and humidity in your baby's room, wine cellar, greenhouse, garage, basement, crawl space, or wherever. This product comes with a 1-year factory warranty.
