A Special Remote. The BAR321HGA comes with a unique remote temperature and humidity sensor and transmitter. The RTGR328NA is a 5-channel remote that contains not only a thermo-hygro sensor but also the atomic clock receiver for the BAR321HGA main station. The remote receives time synchronization signals from the U.S. atomic clock in Colorado (radio station WWVB, 60 kHz) and transmits this information, plus temperature and humidity data, to the BAR321HGA main station via 433 MHz radio waves. As a result, the main station's clock  maintains the same accuracy as the atomic clock.  Please be aware  that the RTGR328NA remote cannot function as an atomic clock receiver for any previous Oregon Scientific time and weather instruments.

The RTGR328NA remote has its own 2-line LCD panel for local viewing. The top line displays the time and a time-signal reception icon. The bottom line displays the selected channel number for the remote and automatically alternates between temperature and humidity. Although the BAR321HGA main station can operate with up to five remotes, only one can be a remote that receives time synchronization radio signals,

and that's the RTGR328NA that comes with the station. The additional remotes are other models that must be purchased separately. When using multiple remotes, be sure to select a different channel number for each.

Optional Remotes. The optional remotes (without time signal reception capability) that work with the BAR321HGA are as follows:

• THGR228N (3-channel sensor).
• THGR268 (3-channel sensor). This is a temperature and humidity sensor with its own display.
• THGR328N (5-channel sensor).
• THR228N (3-channel sensor).
• THR268 (3-channel sensor). This is a temperature-only sensor with its own display.
• THC268 (3-channel sensor). This is a temperature-only sensor with a probe on a 10-foot (3-meter) wire and its own display.

The RTGR328NA, THGR268, THR268, and THC268 are currently available. The three remotes whose numbers end in N are new units that, at the time of this writing, have not yet been released by the manufacturer. Please continue to check this website, as we will be offering these new remotes as soon as we receive them.

Controls and Display. Now, let's get back to what the BAR321HGA actually does. Except for the buttons that select °F or °C for temperature and inHg or mb/hPa for pressure and the RESET button, all station setup and operating functions are controlled by 8 pushbuttons on the right side of the station and the SNOOZE/LIGHT bar on the top. The station's backlit LCD panel has 4 display areas. From top to bottom, these are the weather forecast area, the clock/alarm/calendar area, the temperature/humidity/comfort zone area, and the UVI/barometer area. The forecast icon is continuously displayed. The other 3 areas have multiple user-selectable displays. You use the station's SELECT button to select an areas and additional buttons (e.g., MODE and CHANNEL) to bring up the desired displays in those areas.

Weather Forecast. The weather forecast area displays any of 5 animated forecast icons. The icons indicate Clear, Partly Cloudy, Cloudy, Rainy, and Snowy. The Clear and Partly Cloudy icons have day and night versions. The barometric pressure-based forecast is for 12 to 24 hours in the future. It covers an 19- to 31-mile (30- to 50-km) radius and is 70 to 75 percent accurate.

• Hour, minutes, seconds, month and date.
• Hour, minutes, weekday, date, month. The two-letter weekday abbreviation can be in your choice of English, German, French, Italian, or Spanish.
• Hour, minutes, weekday, plus hour and minutes for a second time zone.
• Hour, minutes, weekday, plus month and date for a second time zone.

Time can be displayed in 12-hour or 24-hour format. Month and date can be shown as month/date or date/month. The language you select for the weekday abbreviation is the language in which time and weather announcements are made if Audio Broadcast is activated. Also, all Audio Broadcast setup is done in the clock setting mode.

The BAR321HGA has 2 alarms. One is a daily alarm, and the other is a pre-alarm for cold, snowy, or icy weather. The daily alarm can be set to go off at the same time every day, and you can select either a crescendo beep pattern or a talking alarm. (If the supplied ac adapter is not plugged in, only the beep alarm is available.) The pre-alarm, when set, sounds only when the daily alarm is activated and the recorded temperature from the Channel 1 remote sensor falls to 2°C (36.5°F) or lower. You can set the pre-alarm to sound 15, 30, 45, or 60 minutes before the daily alarm.

Temperature, Humidity, and Comfort Zone. The temperature/humidity/comfort zone area displays the following:

• Indoor temperature and humidity along with trend arrows for both readings plus the indoor comfort level (wet, comfortable, or dry).
• For the selected remote (Channel 1 through 5), temperature and humidity along with trend arrows for both readings plus the comfort level at the remote's location.

Barometric Pressure and UVI. The UVI/barometer area has 2 display modes:

• In barometer mode, a 24-hour history bar graph is displayed at the top of the area. Below it, current and historical barometric pressure readings are displayed digitally. At the bottom is a digital display indicating hours in the past (0 through 24). You use the HISTORY button to view the barometric pressures recorded at these times.
• In UVI mode (with optional UVR138A UV Radiation Sensor active), you can view a 10-hour UVI record. You can also view acceptable UV exposure times that are automatically calculated based on preset user profiles that you enter (4 users maximum). A UV danger alert is given when the UVI reaches unsafe levels.

You can set the altitude for your location to obtain the correct sea-level barometric pressure reading. The settable range is -100 to +2500 meters (-328 to +8202 feet) in 10-meter increments. 

Audio Broadcast.  As mentioned above, Audio Broadcast setup is done in the clock setting mode, and the broadcast language is the one selected for the weekday display. The supplied ac adapter must be plugged in for the Audio Broadcast feature to work (and also the talking alarm). The BAR321HGA can broadcast the current time, indoor temperature and humidity, and weather forecast. This can be done on the hour for a specified time period (such as 6 p.m. to 10 p.m. nightly) or once every 24 hours at a selected time. You can also set the audio volume level for low, medium, or high. The icon for Audio Broadcast On is displayed in the UVI/barometer area.

Mounting. The BAR321HGA main station comes with both a wall mounting bracket and a table stand, either of which installs easily on the back of the unit.  The RTGR328NA remote sensor can be mounted on a wall, or you can fold out the integral stand and place it on a flat surface.

Powering. The BAR321HGA main station is powered by an ac adapter (7.5 Vdc, 300 mA output) and also requires three AA alkaline batteries primarily for memory backup. The RTGR328NA remote sensor uses two AA alkaline batteries. Both the ac adapter and all five batteries are included. Be sure to install batteries in the remote before you power up the main station. This will ensure that the remote registers properly with the main station. By the way, if you want to use an outdoor remote in sub-freezing conditions, we recommend that you replace its AA alkaline batteries with lithium batteries. Lithium cells retain their power down to about -40°F (-40°C).

Features and Benefits
