The WS-2801A replaces the popular WS-2801. The WS-2801A adds a scroll mode which automatically displays each sensor every 5 seconds. The WS-2801 replaced the WS-2800. The WS-2800 only supported one remote wireless sensor. The WS-2801 supports up to three wireless remote sensors.

The WS-2801A Advanced Wireless Color Forecast Station is packed with features at a very affordable price and includes a logical, easy to read color screen layout.

The WS-2801A features a color forecast icon that reacts to changes in barometric pressure, providing a forecast for upcoming weather in the next 24 to 48 hours with reasonable accuracy.

Equipped with an atomic clock, time is set automatically via radio and in synch with the U.S. atomic clock for utmost accuracy and automatically sets adjusts for daylight savings time.

The remote wireless sensor transmits up to 300 feet line of sight (100 feet under most conditions) includes an LCD display, so the temperature and humidity can be read in both locations.

The WS-2801A supports up to three wireless remote sensors (WH32M), available below.

Optional calibration is provided for the utmost accuracy, Although calibration is optional and not required, the purpose of calibration is to fine tune or correct for any sensor error associated with the devices margin of error and inevitable sensor drift associated with electronic measurements. The measurement can be adjusted from the console to calibrate to a known source.

Other features include min and max that resets daily or manually, barometric pressure trend arrow, and moon phase.

Special Notes and Caveats: The backlight requires AC power to operate. The batteries are intended for back-up power only. The backlight will remain on for 5 seconds when on back up battery power only. The backlight will stay on if you use the AC adapter.

Product Support Questions

If the Radio Controlled Clock does not set on your clock or weather station:

  • Make sure Daylight Savings Time (DST) is set properly. All states except Hawaii and Arizona observe Daylight Savings Time. If you observe DST, make sure this setting is turned ON. The default is OFF (except for the RC-8427)
  • Be patient. Wait at least one week. The RCC is a shortwave signal originating near Fort Collins, Colorado, and travels thousands of miles by bouncing off the ionosphere. The signal is better at night due to solar interference during the daytime. The farther you are from Colorado, the weaker the signal. Urban environments can also effect the signal strength.
  • Locate the console or clock at night near a window or outer wall, and away from other radiating sources, like wireless routers or TVs. This will insure the best reception possible.
  • Test and replace the batteries in the console, if required. Low batteries are often the cause for weak reception.
  • Check your Time Zone Setting. Make sure your time zone is set properly in the display console settings. All times zones in the USA are negative. It is very common for the customer to enter 6 instead of -6 for example.Here is a list of Time Zones:

  1. The sensor receives the radio controlled time and sends it to the console. For the radio controlled clock to work, you must have one or more sensors communicating to the console.
  2. Check the remote sensor for the Radio Controlled Clock (RCC) icon:
  3. If the sensor is receiving the signal (icon is on), try moving the sensor closer to the console.
  4. If the sensor is not receiving the signal (icon is off):
  5. Make sure the sensor is not near or surrounded by metal.
  6. Try moving the sensor to a new location to receive a clear line of sight to the WWVB clock in Colorado.
  7. If the problem persists, please reference:Clock Never Synchronizes To The Atomic Clock, Is Off By Increments Of An Hour, Or Does Not Adjust To Daylight Savings Time (DST)
  8. If the problem persists after reading the Help Article above, the issue is likely with the remote sensor.We have a one year warranty. To replace under warranty, please visit: www.AmbientWeather.com/rma.html.
  9. If out of warranty, a replacement sensor is available here:https://www.ambientweather.com/amwh32m.html

You will want to calculate your barometric pressure to an official reporting station in your area.  Since barometric pressure does not drastically change in a 50 mile radius (unless the weather is rapidly changing), this method of calibration is acceptable.

To determine the relative pressure for your location, locate an official reporting station near you using Ambientweather.net/baro , and set your weather station to match the official reporting station.

To calibrate the relative pressure, you must be in the SET Mode. To enter the SET mode, press and hold the SET button for two seconds. Refer to the table below.

Note that it is the second of the pressure settings. The first changes the pressure units of measure, the second is the relative pressure calibration. It is a common mistake to confuse the two settings.

When the relative pressure is flashing, press the TEMP/+ button to increase the barometer value and BARO/- to decrease the barometer value from the official source.

If you have multiple wireless sensors, while in normal mode, press the SET/CH key to the different channels. Temperature, humidity, and MAX/MIN records will be displayed for each channel.

To scroll automatically, press the channel button again, and the scroll icon   will be displayed next to the channel number, and will scroll every 5 seconds.

To turn off the scroll feature, press the channel button when the scroll icon is on . It will turn off and display channel 1.

Temperature errors can occur when a sensor is placed too close to a heat source (such as a building structure, the ground or trees).

To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Here is an example:

https://www.amazon.com/dp/B00551N8Q2

Bi-metal (dial) and digital thermometers (from other weather stations) are not a good source and have their own margin of error. Using a local weather station in your area is a poor source, due to changes in location, timing (airport weather stations are only updated once per hour) and possible calibration errors (many official weather stations are not properly installed and calibrated).

  1. Place the sensor in a shaded, controlled environment next to the red spirit thermometer, and allow the sensor to stabilize for 3 hours. We recommend bringing both sensors inside.  Compare this temperature to the red spirit thermometer and adjust the console to match the fluid thermometer.
  2. Adjust the temperature from the console.  Note that the sensor will always read the non-calibrated or measured value.
  3. While in the normal node, press and hold the SET/CH and BARO/- keys for five seconds to enter calibration mode (note: the SET/CH mode will appear after three seconds. Continue pressing the two keys until you see the CAL icon appear in the upper right hand corner of the display).
  4. Enter the calibration offset to match the calibration source. Here is a detailed guide for all of the settings:

    Example:
    The calibrated temperature from a red spirit thermometer, or actual temperature is 60.0 °F.
    The uncalibrated or measured temperature is 58.7 °F.
    Offset = Calibrated Temperature – Uncalibrated Temperature = 60.0 – 58.7 = 1.3 °F.
    Enter the temperature offset +1.3 °F.

  1. The backlight has three settings – high, medium and low. Press the LIGHT/SNOOZE button to toggle the screen brightness between HIGH, MEDIUM and
    LOW. If the backlight does not stay on,
  2. Check the AC adapter is working. Remove the batteries but leave the console plugged into AC power. Make sure the console is not on a switched AC outlet. If the console completely powers off, there is a problem with the AC adapter, or the connection to the console.
  3. Unplug and re-plug the AC adapter to make sure it is firmly plugged into the clock.
  4. If you have a volt meter, check for that the AC adapter is working. It should measure about 5 Volts. If the AC adapter measures zero volts, it must be replaced. We have a one year warranty. Please visit: www.AmbientWeather.com/rma.html
    If out of warranty, the AC adapter can be replaced here:https://www.ambientweather.com/amws2800ac.html
  5. If the problem persists, try a factory reset.  To perform a factory reset of the console, press and hold the SET button while the console is
    powering up. After the power up sequence is completed, let go of the SET button.
