Setup
1. Powering the Main Display Unit (Receiver)
- Connect the provided USB charger to the main display unit's power input.
- Plug the USB charger into a standard AC power outlet.
- For backup power during outages, insert 3 x AAA batteries (not included) into the battery compartment on the back of the unit. Note that display brightness control is only available when powered by the AC adapter.
2. Powering and Placing the Remote Sensor (Transmitter)
- The remote sensor comes with a built-in rechargeable battery. Use one of the provided USB charging cables to charge the sensor if needed.
- Place the remote sensor outdoors in a location that is sheltered from direct sunlight and rain for accurate readings. Ensure it is within the 500ft (150m) wireless range of the main display unit. Avoid placing it near large metal objects or strong electromagnetic interference sources.
3. Pairing the Units
- Once both units are powered on, they should automatically pair. The outdoor temperature and humidity readings will appear on the main display.
- If pairing fails, press and hold the "CHANNEL" button on the main unit for 3 seconds to re-enter pairing mode. Then, press the "RESET" button on the remote sensor.

Operating Instructions
Understanding the Display
The large LCD display provides a wealth of information at a glance:
- Indoor Temperature & Humidity: Located on the right side of the display.
- Outdoor Temperature & Humidity: Located on the left side of the display.
- Weather Forecast: Icons at the top center indicate predicted weather (Sunny, Partially Cloudy, Cloudy, Rainy, Snow).
- Barometric Pressure: Numeric value and 12-hour history graph in the center.
- MAX/MIN Records: Displays the highest and lowest recorded temperatures and humidity levels.
- Trend Arrows: Indicate whether temperature, humidity, or barometric pressure are rising, falling, or remaining steady.
- Comfort Level: An indicator showing the comfort level based on indoor humidity.
Adjusting Settings
- Brightness Adjustment: Press the "LIGHT/DIMMER" button on the top of the main unit to cycle through 3 brightness levels.
- Temperature Unit (°C/°F): Press the "°C/°F" button on the back of the main unit to switch between Celsius and Fahrenheit.
- Barometric Pressure Unit (inHg/mb): Press the "inHg/mb" button on the back of the main unit to switch between inches of mercury and millibars/hectopascals.
- MAX/MIN Records: Press the "MAX/MIN" button to view the maximum and minimum recorded values. Press again to clear them.
- Channel Selection: If using multiple outdoor sensors, press the "CHANNEL" button to cycle through the channels (1, 2, 3) and view readings from different sensors.
- Weather Forecast Calibration: The weather forecast is based on barometric pressure changes. To improve accuracy over time, you can manually adjust the forecast icon to match current conditions by pressing the "WEATHER" button on the back of the unit. This helps the unit learn your local weather patterns.
