The 00592W Acu Rite Wireless Indoor Outdoor Thermo-Hygrometer & Moon Phase Atomic Clock is a tall unit with large, easy to read time and weather digits. The display includes indoor and outdoor temperature and humidity, date, day of the week, moon phase display, and in larger numbers, the time.  The time and calendar functions are all atomic, that is, they receive radio broadcasts carrying highly accurate timing information, and set themselves.

At the top of the display is the indoor temperature and humidity display.  Temperature degree and humidity digits are fairly large at 1/2 inch (degree tenths are 1/4 inch). Temperature may be displayed in °F or °C. Pressing the Memory button displays the minimum and maximum temperature and humidity readings experienced since midnight.  Minimum and maximum values are automatically reset every night at midnight.

The second display section indicates outdoor temperature and humidity, in digits the same size as the indoor display. Temperature may be displayed in °F or °C. The Acu-Rite 00592W can receive and display temperature from up to three remote sensors (selectable by the "CH" button).  One remote sensor is included, additional sensors are available separately. Pressing the Memory button displays the minimum and maximum temperature and humidity readings experienced since midnight for any remote channel. These minimum and maximum values are also automatically reset every night at midnight. The remote temperature sensor is white in color and about 3 1/4 inches tall, 2-1/4 inches wide, and 1 inch deep. The sensor has a small temperature display of it's own.  

Below the outdoor display is the date in 3/8 inch digits, followed by a day of the week display.  Below that is the moon phase display which will display one of 8 icons representing the phase of the moon.

Toward the bottom of the display is the time display in 12 hour format.  Hours and minutes are in large 3/4 inch digits, seconds digits are a little less than 1/2 inch.   

The Acu-Rite has alarm clock functionality with an 8 minute snooze alarm.  The alarm is an electronic crescendo alarm. 

Low battery indicators are included on the display to indicate a low battery condition at either the main unit or the remote.

This product comes with a 1-year factory warranty.

Note:  This product has "atomic" clock functionality. Atomic, or Radio Controlled clocks receive a radio signal to set themselves. Like any radio receiver however, they may not be able to receive the signal if they are in a building with a lot of steel in the structure, near computers or other electrical equipment that may generate interference, or if the weather is unsuitable. The signal they receive does not propagate well during the day. That's the nature of the signal, not the clock. These clocks are designed to catch the signal when they can, generally in the middle of the night, calibrate themselves, and then run quite accurately for days until they can catch another signal. When you first put in the batteries, they will most likely not set themselves until the middle of the night. That's normal. By morning, weather permitting, it should be correct. Under less than ideal conditions, it could take a few days. Daylight savings time changes may not be made the first night if location and weather are not favorable.
