Frequently Asked Questions

Temperature reads too high (or inaccurate) when placed in the sun or close to a radiant heat source, like a house, building or structure.

1. Place the sensor inside next to the indoor console sensor. Wait about 1 hour for stabilization. The sensors should agree within the accuracy specifications. Most RTD (resistive thermal device) sensors are accurate within +/- 2 degF. Thus, the sensors should agree within 4 degF.
2. Mercury or red spirit thermometers are very accurate. Inside your house, place a red spirit thermometer next to the digital thermometer. The thermometers should agree within 2 degF.
3. If the sensor is separate, place the sensor in a shaded area on the north side of the structure to avoid direct and radiant heat.
4. Temperature sensors that do not have radiation shields will absorb solar energy and read higher than the ambient temperature. To prevent this problem, purchase a solar radiation shield from Ambient Weather.
5. We have a one year warranty and a 30 day return policy. For details, please visit: www.AmbientWeather.com/rma.html
6. While at the website, enter the part number of the transmitter in the Search by Keyword to locate the product.

What is the correct Timezone/Time Zone setting for my location:

Here is a list of Time Zones:

Note: There are no half settings. Example: If your time zone is 5.5 then you would select a whole number such as 5 or 6.

To set the time mode, you must enter the Time Set Mode. To enter the time set mode, press and hold the TIME button for two seconds.

If your time is still off by one hour:

1. Make sure the Hour Offset is 0 for the USA.
2. Daylight Settings Time may take a day or two to adjust.

This weather station clock receives a signal from the Radio Controlled Clock (RCC) in Colorado.

The display color can interfere with this reception. Thus, a primary color is displayed when the RCC clock in searching for the signal, which occurs about once every 4 hours.

With the RC-8401, the search color was green. However, this was too bright at night for many users.

With the RC-8401A, the search color was changed to red. This color is much softer and will not disturb users.

If the clock backlight is dim, it is possible the backlight control is set to L (Low).

Reference the figure below, #18 and #19 below:

Make sure switch #18 LIGHT is switched to ON.

Make sure switch #19 is set to H (High)

If the backlight is off, make sure the clock is plugged into AC power, and if on a switchable outlet, the switch is turned on.

The clock display color will always display red while the clock is searching for the radio controlled clock (RCC) signal. The mono color red is best for avoiding interference from the display and provides the best opportunity to receive the RCC signal.
