Configuració
1. Alimentació de la unitat principal
- Obriu la tapa del compartiment de la bateria a la part posterior de la unitat principal.
- Introduïu les 3 piles AAA, respectant la polaritat correcta (+/-).
- Tanqueu la tapa del compartiment de la bateria.
- For continuous power, connect the supplied AC power adapter to the DC IN port on the back of the main unit and plug it into a standard wall outlet.
2. Powering the Wireless Outdoor Sensor
- Obriu el compartiment de la bateria del sensor exterior.
- Insert 2 AAA batteries (not included), observing the correct polarity (+/-).
- Tanqueu la tapa del compartiment de la bateria.
3. Sincronització inicial
Upon powering on both the main unit and the outdoor sensor, the main unit will automatically attempt to connect with the outdoor sensor and synchronize with the atomic clock signal. This process may take a few minutes. Ensure the sensor is within range of the main unit.
- If the outdoor temperature/humidity does not display after a few minutes, press the "SENSOR SEARCH" button on the back of the main unit to manually initiate a search.
- The atomic clock signal icon will flash during synchronization and become solid once successfully received.
4. Col·locació del sensor
For accurate readings, place the wireless outdoor sensor in a shaded area, protected from direct sunlight and precipitation. Avoid placing it near large metal objects or electronic devices that could interfere with the wireless signal. The maximum transmission range is approximately 30 meters (100 feet) in open air.
Instruccions de funcionament
1. Visualització de l'hora i la data
The weather station automatically synchronizes with the atomic clock signal for precise timekeeping. No manual adjustment is typically required. The display shows the current time and date.
- To switch between 12-hour and 24-hour format, press the "MODE/SET" button.
2. Visualització de temperatura i humitat
The main unit displays both indoor and outdoor temperature and humidity readings.
- Press the "°C/°F" button to toggle between Celsius and Fahrenheit temperature units.
- A view the 24-hour minimum and maximum temperature/humidity records, press the "TEMP MEMORY" button. Press again to cycle through Min/Max values.
3. Previsió meteorològica
The weather station provides a forecast for the next 12-24 hours based on changes in atmospheric pressure. The forecast is indicated by graphical icons:
- Assolellat: Clear skies expected.
- Partly Cloudy: Barreja de sol i núvols.
- Ennuvolat: Condicions ennuvolades.
- Plujós: Precipitacions previstes.
- Snowy: Snowfall expected (if temperature is low enough).
The forecast is an estimation and may not always reflect actual weather conditions.
4. Indicador de confort
The comfort indicator scale provides a visual representation of indoor comfort levels based on temperature and humidity. It typically displays "COLD", "COMFORT", or "HOT".
5. Funció d'alarma
The unit includes an alarm with a snooze function. Refer to the detailed instructions in the full manual for setting and disabling the alarm.
Manteniment
- Neteja: Wipe the unit and sensor with a soft, damp tela. No utilitzeu netejadors abrasius ni dissolvents.

- Emmagatzematge: If storing the unit for an extended period, remove all batteries to prevent leakage.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| No hi ha cap pantalla a la unitat principal | Les piles estan gastades o mal inserides; l'adaptador de CA no està connectat o està defectuós. | Check battery polarity and replace if necessary. Ensure AC adapter is securely connected and functional. |
| No hi ha lectura de temperatura/humitat exterior | Outdoor sensor batteries are dead; sensor out of range; interference; sensor not paired. | Replace sensor batteries. Move sensor closer to the main unit. Avoid sources of interference. Press "SENSOR SEARCH" button on main unit. |
| Visualització de l'hora incorrecta | Atomic clock signal not received. | Ensure the unit is placed in an area where it can receive the atomic signal (e.g., near a window). Allow time for synchronization. |
| Previsió meteorològica imprecisa | Weather forecast is an estimation based on pressure changes. | This is normal. The forecast is a general guide and not a real-time prediction. |
