Overview

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.

Usage Features:

  • Quick Display Mode: Allows users to quickly toggle between outdoor temperature/dew point and absolute/relative pressure readings by pressing the SET key.
  • Set (Program) Mode: Accessed by holding the SET key for three seconds, this mode allows configuration of various settings including:
    • Daylight Savings Time (DST) ON/OFF
    • Time Zone (TZ) adjustment (-12 to +12 GMT)
    • 12/24 Hour Format
    • Hour, Minute, Year, Month, Day settings
    • Temperature Units (Celsius or Fahrenheit)
    • Calibration for Indoor Temperature, Indoor Humidity, Outdoor Temperature, and Outdoor Humidity.
    • Barometric Pressure Display Units (hPa or inHg)
    • Relative Pressure Calibration (default 29.92 inHg)
    • Pressure Threshold Setting (default level 2, adjustable from 2 to 4 mbar/hour)
    • Storm Threshold Setting (default level 4, adjustable from 3 to 9 mbar/hour)
  • Alarm Mode: Allows users to set high and low alarms for various parameters including time, indoor humidity, indoor temperature, outdoor humidity, outdoor temperature/dew point, and pressure. Alarms sound and flash for 120 seconds when triggered. A snooze feature or 30-second timeout returns to normal mode.
  • Min/Max Mode: Displays maximum and minimum recorded values for indoor humidity, indoor temperature, outdoor humidity, outdoor temperature, and pressure. These values can be reset individually.
  • 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.
