Oregon Scientific THGR228NF Wireless Remote Sensor User Manual

1. Introduction

This manual provides detailed instructions for the setup, operation, and maintenance of your Oregon Scientific THGR228NF Wireless Remote Sensor. This sensor is designed to monitor both temperature and humidity, transmitting data wirelessly to compatible Oregon Scientific weather stations, such as the Ferrari Monza, Ferrari Modeno, or Ferrari Maranello Projection Clock.

The device is splash-proof, making it suitable for various remote outdoor or indoor environments like yards, greenhouses, or auto shops. Please read this manual thoroughly before using the sensor to ensure proper functionality and longevity.

3. Product Overview

The THGR228NF sensor features a clear digital LCD display for local readings and a robust casing designed for remote placement.

This image displays the Oregon Scientific THGR228NF Wireless Remote Sensor. The front features a digital LCD screen showing temperature (30.8°C) and humidity (30%), along with 'DRY' and 'CH 2' indicators. Below the screen, a small red LED indicator is visible. The text '433MHz CABLE FREE' is printed, followed by the 'Oregon Scientific' logo at the bottom. The device has a dark grey casing with a checkered pattern around the LCD display.

Key Components:

• LCD Display: Shows current temperature and humidity.
• Battery Compartment: Located on the back, for AAA batteries.
• Channel Switch: Allows selection of transmission channel (1, 2, or 3) to avoid interference with other sensors.
• Reset Button: Recesses button for restarting the sensor.

4. Setup

4.1 Battery Installation

1. Open the battery compartment cover on the back of the sensor.
2. Insert the two AAA batteries, ensuring correct polarity (+ and -).
3. Close the battery compartment cover securely.

4.2 Channel Selection

Before placing the sensor, select a transmission channel (1, 2, or 3) using the switch inside the battery compartment. If you are using multiple remote sensors, ensure each sensor is set to a different channel to prevent interference.

4.3 Pairing with Main Unit

After installing batteries and selecting a channel, the sensor will automatically begin transmitting data. To receive data on your main Oregon Scientific weather station (e.g., Ferrari Monza, Modeno, or Maranello), refer to your main unit's instruction manual for specific pairing procedures. Typically, this involves initiating a sensor search function on the main unit.

4.4 Placement Guidelines

• Place the sensor within the recommended transmission range of your main weather station (typically up to 30 meters / 100 feet, line of sight).
• Avoid placing the sensor near large metal objects, electrical appliances, or other sources of interference.
• While splash-proof, avoid direct exposure to heavy rain or submersion in water. Position it in a sheltered location if possible.
• For accurate temperature readings, avoid direct sunlight.

5. Operation

5.1 Reading the Display

The sensor's LCD display shows the current temperature in Celsius or Fahrenheit (depending on the main unit's setting or internal switch, if available) and relative humidity. It also indicates the selected channel (e.g., 'CH 2').

5.2 Data Transmission

The sensor transmits data periodically to the main weather station. The red LED indicator on the front of the sensor may flash briefly during transmission.

6. Maintenance

6.1 Battery Replacement

When the battery low indicator appears on the sensor's display or the main unit, replace the batteries promptly. Use only new AAA batteries. Follow the battery installation steps in Section 4.1.

6.2 Cleaning

Clean the sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or display.

6.3 Environmental Considerations

Although splash-proof, prolonged exposure to extreme weather conditions (e.g., heavy rain, direct intense sunlight, freezing temperatures) can affect performance and lifespan. Store the sensor indoors if not in use for extended periods.

7. Troubleshooting

• No display on sensor: Check battery polarity. Replace batteries if low. Press the reset button.
• No data received by main unit:
  • Ensure the sensor and main unit are within range.
  • Verify the sensor's channel matches the channel selected on the main unit for that sensor.
  • Check for sources of interference (e.g., other electronic devices).
  • Re-initiate the sensor search on the main unit.
  • Replace sensor batteries.
• Incorrect readings: Ensure the sensor is not in direct sunlight or near heat/cold sources. Allow time for readings to stabilize after placement.
