Overview

The La Crosse Technology Color Weather Forecast Station is a comprehensive device designed to provide users with detailed weather information and timekeeping functions. It features a vibrant color LCD display that presents various data points in an easy-to-read format, making it a practical addition to any home or office.

Function Description:

The primary function of this weather station is to offer a local weather forecast, outdoor and indoor temperature and humidity readings, and precise time and date information. It utilizes an outdoor sensor to collect external environmental data, which is then wirelessly transmitted to the main display unit. The station's "Intelligent Weather Forecast" feature learns over time, using barometric pressure changes to predict weather conditions for the next 12 hours with an accuracy of 70-75%. This learning process typically takes 7-10 days for calibration.

Usage Features:

The display unit features a clear layout with dedicated sections for forecast, outdoor conditions, and indoor conditions.

  • Forecast: The forecast section displays one of six icons (Sunny, Partly Sunny, Cloudy, Rain, T-Storm, Snow) based on barometric pressure. The "Snow" icon specifically appears when the outdoor temperature is below 32°F and the forecast indicates rain or a storm. Forecast Tendency Arrows indicate whether pressure is rising (improving weather) or falling (worsening weather).
  • Seasonal Trees: A unique visual feature is the "Seasonal Trees," where the trees and foliage color on the display change automatically according to the programmed dates for Spring (March 20th – June 20th), Summer (June 21st – Sept. 20th), Autumn (Sept. 21st – Dec 20th), and Winter (Dec 21st - Mar 19th).
  • Outdoor Conditions: This section shows the outdoor temperature in °F or °C, outdoor humidity, and trend arrows for both. The trend arrows update every 15 minutes, reflecting changes (2°F and 3% humidity) over the past hour. A sensor strength indicator and a low battery icon for the outdoor sensor are also present.
  • Indoor Conditions: Similarly, the indoor section displays indoor temperature, indoor humidity, and their respective trend arrows. A low battery icon for the display unit is also included.
  • Time and Date: The station features Atomic Time, which automatically sets the time and date for accuracy. Users can select their time zone and choose between 12-hour or 24-hour formats. Daylight Savings Time settings are also configurable. The month, date, and weekday are clearly displayed.
  • HI/LO Records: The device tracks and displays the highest and lowest indoor and outdoor temperatures and humidity levels. These records automatically reset at midnight. Additionally, it calculates and shows the outdoor Heat Index and Dew Point.
  • Temperature & Humidity Alerts: Users can set customizable HI/LO alerts for outdoor and indoor temperature and humidity. When an alert value is reached, the display will beep for 5 seconds each minute until the conditions are out of the alert range. The alert sound can be silenced by pressing any button.
  • Backlight: The display unit has an adjustable backlight (HI-LOW-OFF) when operating with the power cable. When running on batteries only, the backlight will briefly illuminate when the LIGHT button is pressed.
  • Sensor Search: A dedicated SEARCH button allows users to manually initiate a search for the outdoor temperature/humidity sensor. The signal strength icon animates during the search until a signal is received or after 3 minutes if no signal is available.

Setup and Configuration:

Initial setup involves powering up the outdoor sensor with 2-AA batteries and plugging the power cable into the display. Optional 3-AA batteries can be inserted into the weather station for backup. Basic settings like time, date, time zone, and temperature units (°F/°C) are configured through a step-by-step menu accessed by holding the SET button. The outdoor sensor should be placed in a shaded location after 5 minutes of power-up, ideally on a north-facing wall, under an eave, or on a deck rail, mounted vertically to drain moisture. The maximum wireless transmission range for the sensor is over 300 feet in open air, without walls or floors obstructing the signal. For optimal Atomic time reception, the display should be oriented with the front or back facing Ft. Collins, Colorado, and placed at least 6 feet away from other electronics.

Maintenance Features:

  • Battery Replacement Indicators: The display shows low battery icons for both the outdoor sensor and the main display unit, prompting users to replace batteries when needed.
  • Battery Care: The manual provides guidelines for battery care, including not mixing old and new batteries, not mixing different battery types (Alkaline, Standard, Lithium, Rechargeable), purchasing the correct size and grade, replacing all batteries in a set at the same time, and promptly removing expired batteries.
  • Cleaning: While not explicitly detailed in the provided text, general care for electronic devices typically involves cleaning with a soft, dry cloth and avoiding harsh chemicals.

The La Crosse Technology Color Weather Forecast Station is designed for user-friendliness and provides a wealth of environmental data to help users stay informed about their local weather and indoor conditions.
