The Acu-Rite 00684L "Garden Decor" Wireless Digital Weather Forecasting Center displays both the indoor temperature and, as received from the included remote sensor, the outdoor temperature. Maximum range of the remote sensor is 100 feet, and the main unit can accommodate up to 2 sensors. In addition, the 00684L displays the indoor relative humidity and, above it, a weather forecast icon along with a barometric pressure trend arrow. The 00684L also contains a precision digital quartz clock, and the time can be displayed as an alternative to the indoor humidity. The main unit can be mounted on a wall or placed on a shelf, table, or desk.

This wireless digital weather station monitors and displays the temperature both indoors and in up to 2 remote/outdoor locations by means of the included remote sensor and 1 additional remote sensor, which is optional and sold separately. Also displayed is the indoor relative humidity (if selected instead of the current time).

Temperatures can be displayed in either °F or °C, as selected via pushbutton. Four different modes of temperature alert can be programmed for each remote channel in use. These are:

• In Between: Alert activates when the temperature enters the preset range.

• Out of Range: Alert activates when the temperature goes outside of the preset range.

• Lower Than: Alert activates when the temperature goes outside of the preset range.

• Higher Than: Alert activates when the temperature goes outside of the preset range.

The weather center's integral memory records maximum and minimum values for indoor temperature, indoor relative humidity, and outdoor/remote temperature for each remote sensor in use. These values are available at the push of a button, and you can easily clear and reset the memory if desired.

Four different weather-forecasting icons can be displayed on this weather center: Sunny, Partly Sunny, Cloudy, and Rainy. Each provides an accurate forecast for the next 12 to 24 hours based on barometric pressure. If the forecasting icons do not seem to be indicating and updating accurately according to the weather, you can manually calibrate the station so that the icons read and update properly. Such inaccuracies can occur, for example, if you live at an altitude where average barometric pressure is significantly lower than at sea level. Displayed along with the forecast icon is a barometric pressure trend arrow that indicates increasing, steady, or falling.

The Acu-Rite 00684L uses only one model of wireless remote temperature sensor: the Acu-Rite 00689. One 00689 is included with the station, and the station accepts up to two. The additional sensor is sold separately. The 00689 features a water-resistant case and is designed for wall mounting. This can be done either via the included two-sided tape or via two included screws that are used to secure the case's outer back cover to a wall (the outer cover acts as a mounting bracket). Mount the sensor away from direct sunlight and rainfall.

The 00689 sensor has an attached, submersible probe on a 3-foot wire that tucks into a compartment at the bottom of the sensor case. For monitoring of remote indoor temperatures (such as in a wine cellar or greenhouse) or of outdoor temperatures above +12°F ( -10°C), you need not pull the probe from the sensor case. For colder temperatures, however, you should bring the sensor indoors so the battery doesn't freeze, extend the wire, and place the probe out of a window. You'll also need to extend the wire and probe if you want to monitor the temperature in a freezer, in a liquid (e.g., in a pool, spa, aquarium, or pond), or in soil.

The 00689 remote sensor can transmit up to 100 feet (30 meters) without outside interference, i.e., in an open area. The 00684L center has a user-selectable auto-scroll feature by which each active remote sensor's temperature reading is displayed for 5 seconds.

This weather station also features a precision digital quartz clock that indicates hour, minutes, and seconds in either 12- or 24-hour mode (user-selectable). Please note that this is a regular digital quartz clock--not a radio-controlled, or "atomic," clock.

Operating temperature range of the station main unit is 32° to 122°F (0° to 50°C). Operating temperature range of the remote sensors is -58° to +158°F (-50° to +70°C).

If you're looking for a medium-small wireless digital weather station with big, bold LCD displays (main numbers about 7/8-inch tall)--plus special features such as min/max memory for temperature and humidity and a choice of 4 temperature alert modes--the Acu-Rite 00684L surely deserves your serious consideration.

All required batteries are included and preinstalled in both the main unit and the remote sensor. All you need to do is access them according to the instructions and remove the insulator strips. The main unit uses two AA (1.5V) batteries, and the remote sensor uses one 9-volt battery. We strongly recommend alkaline cells when replacement time comes around. The main unit displays a low-battery indication when its batteries or the battery in a remote sensor becomes weak.

This wireless digital weather forecasting center is perfect for the serious weather watcher or for the novice--and for any room in the house, or your office. It comes with a 1-year factory warranty.
