Frequently Asked Questions - DME 3228 Trevi

How to install the outdoor sensor?

Place the sensor outdoors sheltered from weather (under an eave). Insert 2 AAA batteries, then turn on the station. The signals pair automatically within 3 minutes.

What to do if the outdoor display stays at '--'?

Check the sensor batteries and distance (max 30 m). Press the RESET button on the sensor and reset the station by removing the batteries for 10 seconds.

How to set the time and alarm?

Press and hold SET to enter setting mode. Use +/- to change values. For the alarm, press ALARM then set similarly.

Is the atmospheric pressure calibrated?

The station displays relative pressure (altitude compensated). For more accuracy, set your location's altitude via the SET menu.

How to change the temperature unit (°C/°F)?

Press the °C/°F button on the back of the station to toggle between the two units.

Why doesn't the forecast icon match the actual weather?

The forecast is based on barometric trends over 12 hours. Sudden changes may not be immediate. Ensure the sensor is properly positioned.

Can I add a second outdoor sensor?

This model supports only one outdoor sensor. For multi-sensor stations, refer to a compatible model.

How to replace the batteries?

Open the battery compartment on the back of the station or sensor. Use branded alkaline batteries. Replace after change.

The station does not turn on

Check that batteries are inserted correctly (polarity). Try a new set of batteries. If nothing, press RESET with a paperclip.

METEO STATIONBATTERY & ADAPTEBATTERY & ADAPTER INSTALLATION

Home Receiver Unit:

Main Power Source: Plug in the 6.0V adapter into the adapter socket at the back for basic operation and continuous backlight. Backup Power: Lift off the battery cover, install 3 pieces of AAA backup batteries according to the polarity indicated, close the battery cover.

Remote Sensor:

Loosen the screws on the battery door with a small screwdriver, insert 2 pieces of AAA batteries according to the polarity indicated. Replace the cover and tighten the screws.

ALTITUDE SETTING

After inserting batteries or adapter, the main unit will enter altitude setting mode directly. Press "▲" or "▼" to select pressure unit in

hPa, mb or inHg. Press "PRESSURE" to confirm. Then press "or "to enter your current altitude in meter or feet. Press "PRESSURE" to confirm and exit the setting. This allows the unit to provide a more accurate barometric pressure & weather forecast reading. (For more information, see "WEATHER FORECAST & BAROMETRIC PRESSURE" section)

SETTING UP THE WIRELESS THERMO-HYGROMETER:

• For the first installation, always turn on the home unit and then the remote sensor. Set Channel 1 for the first remote sensor. Set channel 2 and channel 3 for the 2nd and 3rd sensor.
• Press and hold CHANNEL/SEARCH button on main unit until a beep is sound to search for remote sensor.
• Press the Tx button on the back of remote sensor to transmit RF signal.
• When RF connection is established, the respective temperature & humidity of the selected channel will appear on the main unit.

WEATHER FORECAST & BAROMETRIC PRESSURE

The unit predicts weather condition of the next 12 – 24 hours based on the change of atmospheric pressure. The coverage area is around 30 – 50 km. The weather forecast is based on atmospheric pressure change and is about 70-75% correct. As weather conditions cannot be 100% correctly forecasted, we cannot be responsible for any loss caused by an incorrect forecast.

To obtain an accurate weather forecast & barometric pressure reading, you need to input your current altitude. After the reset of the unit, it will enter altitude setting mode. Press "▲" or "▼" to set the pressure unit in hPa, mb or inHg. Press "PRESSURE" to confirm.

Then enter your current altitude in meter or feet. Press "PRESSURE" to confirm and exit the setting.

You can also hold "PRESSURE" button to enter altitude setting mode during normal use.

Press PRESSURE button to select pressure unit between hPa, inHg & mb.

IN/OUT TEMPERATURE & HUMIDITY

Temperature reading is located on the upper left of the display and humidity is on the right of the temperature. Press "C/F" button to select temperature unit C/F.

Press CHANNEL/SEARCH button to select indoor, Ch1, Ch2, Ch3 and auto-channel scrolling display modes.

IN/OUT HEAT INDEX

Heat Index combines the effects of heat and humidity. It is the apparent temperature of how hot the heat-humidity combination makes it feels.

Press "Heat Index/Dew Point" button once to show the respective indoor or outdoor heat index on the upper left display. "HEAT INDEX" icon will appear.

HEAT INDEX ALERT INDICATOR

During conditions indicating a high heat index, a Heat Index Alert Indicator will appear on screen.
