Why is my Ambient Weather Station wireless remote not reporting to the console?
- K
  katieriosAug 12, 2025
  There could be several reasons why your Ambient Weather Station's remote isn't reporting to the console. First, try resynchronizing the unit by pressing and holding the + key for 10 seconds. Also, check that the remote sensor is powered on and displaying temperature and humidity. Installing a fresh set of batteries in the remote thermo-hygrometer can help. Ensure the sensor isn't transmitting through metal or earth barriers. You might need to move the sensor assembly closer to or away from the display console, or move the console away from electrical devices. Also, consider moving the remote sensor to a higher location.

Why doesn't the relative pressure agree with the official reporting station on my Ambient Weather Station?
- D
  Donald RodriguezAug 16, 2025
  The relative pressure on your Ambient Weather Station may not agree with an official reporting station if you are viewing the relative pressure instead of the absolute pressure. Make sure you properly calibrate the barometer to an official local weather station. Also, the barometer is only accurate to ± 0.08 inHg.

  If your Ambient Weather Station's display console shows dashes, try these steps: Resynchronize the unit by pressing and holding the + key for 10 seconds. Check that the remote sensor is powered and displaying temperature and humidity. Install a fresh set of batteries in the remote thermo-hygrometer. Adjust the sensor's position; it may need to be closer to or further from the console. Ensure there are no metal or earth barriers interfering with transmission. Also, move the display console away from potential sources of electrical noise.

Why doesn't the forecast icon seem accurate on my Ambient Weather Station?
- M
  Melissa WilliamsAug 25, 2025
  The forecast icon on your Ambient Weather Station may not be accurate initially because the console needs several days to trend barometric pressure. Keep in mind that the weather forecast is an estimation of weather changes within the next 24 to 48 hours.

Why does the Ambient Weather Station temperature sensor read too high during the day?
- M
  Marie KellyAug 27, 2025
  If your Ambient Weather Station's temperature sensor reads too high during the day, ensure the thermo-hygrometer is mounted in a shaded area on the north-facing wall.

The Ambient Weather WS-1171A is an advanced weather station designed for home use, providing real-time temperature, humidity, and barometric pressure readings, along with weather forecasting. It consists of a display console (receiver) and a thermo-hygrometer (remote transmitter).

Function Description:

The primary function of the WS-1171A is to monitor indoor and outdoor environmental conditions. It displays indoor and outdoor temperature and humidity, barometric pressure (absolute and relative), and provides a weather forecast based on pressure changes. The station also features a Radio Controlled Clock (RCC) for accurate timekeeping, an alarm mode for various weather parameters, and a Min/Max mode to track extreme readings. The weather forecast includes icons for Sunny, Partly Cloudy, Cloudy, and Rainy, along with a weather tendency indicator to show increasing or decreasing air pressure. A storm threshold indicator can be adjusted by the user to signify an expected storm. The device also includes a pressure graph displaying barometric pressure for the last 24 hours.

Weather Forecasting: Provides an estimation of weather changes for the next 24 to 48 hours based on barometric pressure trends. Includes animated arrows to indicate improving or deteriorating weather.
Radio Controlled Clock (RCC): Automatically receives and sets the time, with a WWVB icon indicating successful reception. The outdoor sensor transmits weather data for 30 seconds, then attempts RCC reception for up to 10 minutes. If unsuccessful, it retries every two hours.
Sensor Operation Verification: Users are advised to place the remote sensor 5-10 feet from the console initially to verify readings and allow stabilization.
Restoring Lost Outdoor Sensor Signal: If the remote sensor signal is lost, users can press and hold the '+' key for 10 seconds to re-synchronize the unit.

Maintenance Features:

Battery Replacement: The console uses 3 x AA batteries, and the remote sensor uses 2 x AAA batteries. Users are advised to note battery polarity and use fresh batteries, with lithium batteries recommended for cold climates in the remote sensor.
Calibration: The device offers calibration for indoor and outdoor temperature and humidity, as well as relative barometric pressure, to ensure accuracy. For humidity calibration, an accurate source like a sling psychrometer or salt bath kit is recommended. For temperature, a fluid thermometer is suggested.
Troubleshooting Guide: The manual includes a comprehensive troubleshooting section for common issues such as lost remote sensor signals, dashes on the display, inaccurate temperature/humidity readings, and incorrect relative pressure. It provides steps like re-syncing the unit, checking batteries, repositioning sensors, and performing calibrations.
Wireless Reception Considerations: The manual provides guidance on factors affecting wireless signals, such as distance, interference from other electronic devices, and transmission barriers (e.g., solid metal, thick walls), and suggests optimal sensor placement (north-facing wall, shaded area, at or above receiver height).
Product Revisions: The manual details product revisions, including added humidity and temperature calibration, increased programming timeout, changes to the barograph display, and a function to reacquire lost remote signals without powering down the console.
Environmental Responsibility: Users are encouraged to return used batteries to an authorized depot for proper disposal, as electrical and electronic waste contains hazardous substances.
