Indoor Comfort Level Indicator

Using relative humidity (RH), these indicators show your indoor comfort level, helping to keep your home safe and comfortable.

Note: The visual indicators are arrows showing WET, GOOD, or DRY states.

Forecast

The forecast icons use the station's internal barometer to predict conditions for the next 12 hours. The Snow icon appears when temperatures are below 0°C (32°F) and rain or storms are predicted.

• [t-storm-icon] T-STORM: Thunderstorm
• [snow-icon] SNOW: Snow

The sun icon displays during daylight hours, and the moon icon displays during nighttime hours for sunny or partly sunny forecasts.

Pressure / Extra Sensor Area

Pressure: Your Relative Pressure reading comes from the station's internal barometer. Allow up to 10 days for automatic calibration, or manually program your local pressure value in the Settings Menu. Arrows on the left indicate rising [pressure-rising] or falling [pressure-falling] pressure tendency.

Extra Sensors (sold separately): This station can display data from up to 3 additional Temperature/Humidity or Rain Sensors.

To Add Extra Sensors:

1. Install batteries into your extra sensor(s). For Temperature/Humidity sensors, ensure you select different channels (1, 2, or 3) before inserting batteries (channel switch is inside the battery compartment).
2. Hold the [extra-button] EXTRA button until the Reception Indicator animation starts, indicating a sensor search.
3. Sensors should connect within minutes. Press the [extra-button] EXTRA button to cycle through Extra Sensor and Pressure data. The Auto Scroll Icon will appear when activated. Press the [extra-button] EXTRA button again to stop auto-scrolling.
