    Product overview guide for the La Crosse Alerts TX60U-IT Wireless Remote Temperature/Humidity Monitor — a wireless ambient sensor (with optional external temperature probe) that uploads readings to your La Crosse Alerts online account for remote monitoring and text/email alerts.

    Important — Set Up Online

    This document provides general product information and specifications only. Complete set up and activation instructions are online at www.lacrossealerts.com. First, create an account, then choose model TX60U-IT on the website to begin the step-by-step setup process. Enter the key from the included Activation Key Card when prompted.

    General Use and Applications

    Use a smartphone, tablet, or computer to remotely monitor ambient temperature and humidity affecting your home, second home, office, or rental property. The 6-foot detachable dry probe measures temperature of air outside a window, or inside a refrigerator or freezer. Text and email alerts can flag power outages to help protect property or prevent frozen pipes.

    Monitoring Options

    • Home, second home, office, or rental property
    • Indoor or outdoor temperature and humidity
    • Basement, garage, attic, and utility room
    • Refrigerators, freezers, and dry food storage
    • Plants, gardens, and greenhouses
    • Outdoor pets, farms, and livestock
    • Books, photos, and musical instruments
    • Computers, servers, and electronics
    • Wine storage and humidors
    • Fireplace mantel

    Package Contents

    • Wireless Ambient Temperature and Humidity Monitor with mounting bracket (TX60U-IT)
    • Optional temperature probe on 6 ft. detachable cable (select packages only)
    • Internet Gateway with mounting bracket, AC adapter, and LAN cable
    • Mounting hardware (screws and drywall anchors)
    • Printed Product Overview Guide (this document)
    • Activation Key Card — required for setup and activation of every device; do not throw away

    Additional equipment needed (not included): two fresh AAA alkaline batteries, two-sided tape as needed, a browser with high-speed internet, and a network router.

    Features and Measurements

    (A) Wireless Ambient Temperature & Humidity Monitor:

    • LCD displays ambient air temperature and humidity (CH1)
    • LCD displays probe temperature (CH2)
    • Transmits collected data to the Internet Gateway within a 200 ft. wireless range
    • Weather-resistant case (not waterproof) — the case with LCD cannot get wet and may be affected by high humidity
    • Wall-hanging or free-standing

    (B) Optional Temperature Probe on 6 ft. Detachable Cable: Wet and dry temperature probes sold separately; attach a probe at any time with no need to reset the sensor. Attach a dry probe (Model #D000.101.BG) to monitor dry environments like air or soil, or a wet probe (Model #D000.102.BG or D000.103.BG) for wet/humid conditions such as a pool, aquarium, or terrarium. The socket on the sensor is ONLY for the external probe — do not insert a power plug into it.

    How It Works

    • The wireless sensor transmits temperature and humidity data to the Internet Gateway (200 ft. wireless range).
    • The Internet Gateway connects to your existing network router and uses your internet connection to upload measurements to your account at www.lacrossealerts.com.
    • Once activated, monitor sensors online from a smartphone, tablet, or computer, and set up custom email/text alerts.
    • Add up to 5 sensors (sold separately) per Internet Gateway to monitor additional areas.

    Setup and Activation

    1. Begin setup near your existing network router and a computer with high-speed internet access.
    2. Unpack the package and insert the temperature probe into the TX60U-IT case, if applicable.
    3. Locate the Activation Key Card in the package for setup instructions and the Activation Key. A unique key is necessary to activate your sensor and Internet Gateway — keep this card for reference.
    4. Visit www.lacrossealerts.com with your Activation Key Card to create your account and activate the product.

    Activation info: the included Activation Key provides 1 year of Enhanced Service (early-warning text and email alerts) plus 4 more years of Basic Service (standard remote monitoring) — a total of 5 years.

    Select a Location to Mount the Sensor

    • Choose a location protected from water and precipitation. The case is water-resistant, not waterproof.
    • Place the sensor in a dry, shaded area — avoid direct sun to prevent inaccurate readings.
    • Fog and mist won't harm the sensor, but direct precipitation must be avoided.
    • Extreme humidity may temporarily disrupt data; the sensor case should not be submerged in water.
    • Select a location within range of the Internet Gateway.

    Confirm Connection Before Mounting

    Important: Before permanently mounting, test the sensor in the desired location for at least 1 hour to confirm good reception. Confirm consistent readings in your online account before permanently mounting — move the sensor closer to the Internet Gateway if signal is lost or not received.

    Mounting Instructions

    Mount to Wall with Screws

    1. Remove the mounting bracket.
    2. Place the bracket over the desired location.
    3. Mark the mounting surface with a pencil through the 2 holes of the bracket.
    4. Screw the bracket onto the surface and tighten screws.
    5. Insert the sensor back into the bracket.

    Free Standing

    Attach the mounting bracket to the bottom or top of the sensor and place it on any flat surface.

    Placement of Temperature Probe (Optional)

    • Confirm the probe cable end is secured in the socket inside the sensor.
    • Insert the dry probe (Model #D000.101.BG) into a refrigerator, freezer, or dry soil for a separate air/soil temperature reading. The dry probe wire is not for use in water — use the optional wet probe (Model #D000.102.BG or D000.103.BG) for wet environments instead.
    • Loosely coil and secure extra cord with a twist tie or tape (not included).

    Important Setup & Operation Notes

    • The sensor has a wireless range of 200 feet in open air with no obstructions — radio waves do not curve around objects. Each obstruction (roof, walls, floors, ceilings) effectively cuts signal range in half.
    • Metal, stucco, and some types of glass can reduce signal range by ¾ or more, compared to the typical ½ reduction from most obstructions.
    • The sensor measures and updates temperature and humidity on the LCD every 6 seconds; the new measurement is reported to your account at intervals you select online.

    Measurement Log Download

    Once activated and building a measurement log, you can download data as a CSV file (viewable in Microsoft Excel, Google Docs, or similar applications).

    Battery Replacement

    1. Remove the battery cover by sliding it down.
    2. Install 2 AAA batteries observing correct polarity, ensuring they fit tightly (avoid start-up problems from batteries springing free).
    3. Do not mix old and new batteries, or mix alkaline, lithium, standard, or rechargeable battery types.
    4. Replace the battery cover by sliding upward and confirm it's securely fitted.

    Low Battery Indicator

    A low-battery icon appears on the LCD when batteries run low, and you'll receive an email or mobile text alert — change the batteries immediately. The LED light turns on briefly after changing batteries and then turns off to save power. Previously stored data is not affected by a battery change.

    Maintenance and Care

    • Avoid extreme temperatures, vibration, and shock.
    • Clean the sensor with a soft, damp cloth — no solvents or scouring agents.
    • Do not submerge the sensor case in water or kink the 6 ft. sensor cable.
    • Secure the 6 ft. cable to avoid tripping hazards.
    • Immediately remove low-powered batteries to avoid leakage and damage.
    • Opening the casing invalidates the warranty — do not attempt repairs; contact La Crosse Technology for service.
