Digitech XC0412 Wireless Weather Station User Manual

Wireless Thermo-Hygro Sensor

Description of Sensor Components:

• 1. LED indicator: Flashes when the remote unit is transmitting.
• 2. LCD display: Shows the detected temperature or humidity of the sensor.
• 3. Wall mounting holder: For mounting the sensor.
• 4. [RESET] key: Press to restart the sensor.
• 5. [CHANNEL] slide switch: Assigns the transmitter to Channel 1, 2, or 3.
• 6. Battery compartment: Accommodates 2 x AA size batteries.

Getting Started: Wireless Sensor

1. Remove the battery door.
2. Insert 2 x AA size batteries into the battery compartment, ensuring correct polarity.
3. Replace the battery door.

Note: Once a channel is assigned, it can only be changed by removing batteries or resetting the sensor. Pairing with the main unit requires holding the [12/24 / ] key for 3 seconds. If the unit fails to receive wireless signals after replacing batteries, repeat the pairing process. Avoid placing the transmitter in direct sunlight, rain, or snow. Building materials and positioning affect the effective range (up to 30 meters). Minimize interference by placing units away from metal objects and electrical appliances.

Reading Indoor/Outdoor Temperature & Humidity

In normal mode, press the [°C / °F] key to switch between Celsius (°C) and Fahrenheit (°F) temperature units. The temperature and humidity will display "HI", "LO", or "--" under specific conditions:

Note: If no signals are received or transmission is interfered with, "--" will appear on the LCD. Relocate the clock or transmitter to ensure transmission is within the effective range (approx. 30 meters).

Baro, Temperature and Humidity Trend

The Barometric pressure, temperature, and humidity trend indicators show changes over the next few minutes. Arrows indicate the trend:

• [rising trend arrow]: Rising trend
• [steady trend arrow]: Steady trend
• [falling trend arrow]: Falling trend

Barometric/Atmospheric Pressure

To Select Pressure Display Mode:

Press and hold the [BARO] key for 2 seconds to enter the mode selection, allowing you to choose between:

• abs: Absolute atmospheric pressure of your location.
• rel: Relative atmospheric pressure based on sea level.

To Set Relative Atmospheric Pressure Value:

1. Obtain the sea-level atmospheric pressure data (also the relative pressure for your area) from local weather services or the internet.
2. Press and hold the [BARO] key for 2 seconds until the "abs" or "rel" icon flashes.
3. Press the [CH / ] or [12/24 / ] key to switch to "rel" mode.
4. Press the [BARO] key again until the relative atmosphere pressure digit flashes.
5. Use the [CH / ] or [12/24 / ] keys to adjust the value.
6. Press the [BARO] key to save and exit, or the unit will exit automatically after 30 seconds of inactivity.

To Select Measurement Unit for Barometer:

Use the [BARO] key to change the unit between hPa (mb) and inHg.

Notes:

• Upon power-up, the main unit displays the relative pressure reading with a default value of 1013 mb/hPa (29.91 inHg), representing average atmospheric pressure.
• Changing the relative atmosphere pressure value will affect the weather indicators.
• Relative atmosphere pressure is based on sea level but will adjust based on absolute pressure changes after about 1 hour of operation.

Weather Forecast

The built-in barometer monitors atmospheric pressure changes to predict weather conditions for the next 24 to 72 hours:

• [sunny icon]: Sunny
• [partly cloudy icon]: Partly Cloudy
• [cloudy icon]: Cloudy
• [rainy icon]: Rainy
• [stormy icon]: Stormy
• [snowy icon]: Snowy

Notes:

• The accuracy of pressure-based weather forecasts is approximately 70% to 75%.
• The forecast is for the next 24 to 72 hours and may not reflect the current situation.
• The "Snowy" weather indicator is based on temperature, not atmospheric pressure. It displays when the outdoor temperature is below -3°C.

Past 24 Hours History Pressure Record

The current and historical atmospheric pressure is shown near the 24 HOUR FORECAST section. To view pressure history for a specific hour within the past 24 hours, press the [HISTORY] key. Each press moves back one hour. Press any key other than [HISTORY] to return to normal mode, or the unit will exit automatically after 30 seconds.

Max / Min Record

The main unit stores the maximum and minimum temperature and humidity data since the last manual reset.

1. In normal mode, press the [MEM] key once to display the maximum indoor and current outdoor channel temperature and humidity records.
2. Press the [MEM] key repeatedly to view the minimum records.
3. Press the [MEM] key again to exit the record view.
4. To erase all MAX/MIN records, press and hold the [MEM] key for 3 seconds.

Moon Phase

The main unit displays the northern hemisphere moon phase status. The table below illustrates the moon phase icons:

Low Battery Icon

When the [low battery icon] appears on the clock section or the LCD becomes dim, replace the batteries in the main unit with 2 new AA size batteries. If the [low battery icon] appears in the outdoor sensor section, replace the transmitter's batteries with 2 x AA size batteries.

Important Notes

• This main unit is intended for indoor use only.
• Do not subject the unit to excessive force, shock, dust, extreme temperatures, or humidity.
• Do not cover ventilation holes with items like newspapers or curtains.
• Do not immerse the unit in water. If liquid is spilled on it, dry immediately with a soft, lint-free cloth.
• Do not clean the unit with abrasive or corrosive materials.
• Do not tamper with the unit's internal components, as this invalidates the warranty.
• Use only fresh batteries. Do not mix new and old batteries.
• Dispose of old batteries separately as unsorted municipal waste, requiring special treatment. Dispose of used units or batteries in an ecologically safe manner.
• Technical specifications and user manual contents are subject to change without notice.
