Q: How long does it take for the Lisbon Marathon to display the outdoor temperature?

The Lisbon Marathon displays the outdoor temperature a few minutes after inserting the batteries of the outdoor sensor. Here is the exact process: Step 1: Once the batteries of the outdoor sensor are inserted, it automatically starts transmitting temperature and humidity conditions to the weather station. Step 2: The main unit automatically receives this data once you have set the current weather conditions on the main screen. Step 3: The RF icon appears on the LCD screen confirming that communication is established and the outdoor temperature begins to display. If the temperature does not appear: The display “ --.--.-- ” will appear on the screen. This means that the station has failed to receive transmissions from the outdoor sensor. Press and hold the SEARCH button for 3 seconds to manually reset the transmission. Important points for optimal reception: The transmission range is 70 meters in open areas (without obstacles such as buildings, trees, or vehicles). Check that: The batteries of the outdoor sensor are in good condition and properly inserted. The distance between the sensor and the station does not exceed 70 meters. There are no significant obstacles between the sensor and the station (thick walls, metal structures). The sensor is securely and vertically mounted on a surface. Once these checks are made and after a few minutes of operation, the station will correctly display the outdoor temperature.

Question 1

How to connect the sensor to the Marathon Lisbon weather station?

Accepted Answer

To connect the wireless sensor to your Marathon Lisbon weather station, follow this procedure:

Preparing the devices — Insert 2 AA batteries into the battery compartment of the outdoor sensor, respecting the indicated polarity. Likewise, power the main weather station (batteries or power adapter). Wait a few seconds for both devices to power on.

Starting the synchronization — On the weather station, press and hold the SEARCH button (button B7) for 3 seconds. The station will then start searching for the outdoor sensor. The sensor will automatically transmit its RF signal at 433 MHz.

Checking the connection — Observe the LCD screen of the station. The appearance of the RF icon confirms that the transmission was successful and that the sensor is connected. The outdoor temperature and humidity will then display normally. The connection should be established within minutes.

In case of failure — If the screen displays “--.--” instead of temperature values, it means that the station did not receive the transmission from the sensor. Check that the sensor's batteries are fresh and properly inserted, then press the SEARCH button again for 3 seconds to restart the search.

Positioning the sensor — Place the outdoor sensor in a vertical position on a stable surface, sheltered from the elements but in an airy area for accurate measurements. The theoretical range is about 70 meters in open space, but decreases in the presence of obstacles (walls, metals, structures). Ensure that the sensor is not exposed to temperatures below -20 °C or above 50 °C, beyond which its operation may be compromised.

Once connected, the sensor will regularly transmit temperature and humidity data to the station. If the signal is lost later, proceed in the same manner by pressing the SEARCH button to restore the connection.
