Ambient Weather WS-2800-AC Replacement AC Adapter, WS-2700, WS-2800, WS-2801 and WS-2801A Wireless Weather Station

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:

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.

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.

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:

1. Remove the batteries
2. Disconnect from AC Power.
3. Press and hold the SET button.
4. Reconnect AC Power.
5. Wait for power up sequence to complete (about 10 seconds)
6. Let go of the SET button.

If the time is incorrect by multiples of an hour, you likely set the incorrect time zone. The most common issue for users in the USA is to set a positive time zone instead of a negative time zone (example, +5 instead of -5).

The following table summarizes time zones around the world.

Make sure your time zone agrees with the time zone programmed into the console SET MODE:

The Ambient Weather WS-2800 only supported one outdoor sensor.

The WS-2801 added three channel sensor support.

The WS-2801A added scroll mode to the WS-2801.

The WS-2700 Removed AC power requirement for console.

To turn the beep off, you must be is SET Mode. To enter the SET mode, press and hold the SET button for 2 seconds, and the function BEEP will flash. Press the TEMP/+ button to toggle on or off.

The WS-2800 only supported one remote wireless sensor. The WS-2801 supports up to three wireless remote sensors.

The WS-2801A adds scroll mode, which allows you to view all three channels without pressing any buttons.

While in normal mode, Press (do not hold) the TEMP/+ key to view the Dew Point in the outdoor temperature field. If key idle 30 seconds, the display will return to normal mode.

To exit the Dew Point display mode, press the SNOOZE/LIGHT key (on the top of the display console), or wait 30 seconds for the timeout to take effect.
