Getting started

Pre-installation checkout Before permanent installation, it is recommended to use the weather station for a week in easily accessible temporary location. This will allow you to test its performance, to become familiar with its functions and controls, and to determine its wireless range.

Site survey

Perform a survey of the site before installation. Consider the following:

• Maintenance access. Regularly clean the rain gauge and swap batteries every 2−3 years. Ensure easy access to the weather station.
• Radiant heat from buildings and structures. Install the multisensor at least 1.5m from any buildings, structures, ground, or rooftops.
• Rain and wind obstructions. For precise measurements of wind and rain, install the multisensor at a height at least 4 times that of the nearest obstacle. For example, if the building is 6m tall, and the mounting pole is 2m tall, the sensors should be installed at a height of at least 16m (4 х (6−2)).
• Wireless range. The optimal distance between the receiver and the transmitter is up to 100m in an open space. With obstacles in the way (buildings, trees, etc.), the maximum distance is 30m.
• Radio interference from computers, radios, or TVs. Install the display console at least 1.5m away from electronic devices to minimize interference.

Sensor setup

Installing U-bolts and the mounting pole Install the included metal plates to secure the U-bolts (8) to the mounting pole. The metal plate is inserted into the groove on the bottom of the device (opposite side from the solar panel (6)). One side of the plate has a straight edge (inserted into the groove), the other side is bent at a 90-degree angle and has a curved profile that wraps around the mounting pole. After inserting the metal plate, remove the nuts from the U-bolts and insert both bolts into the corresponding holes in the plate. Screw the nuts onto the ends of the U-bolts. Make sure to tighten them completely during final mounting.

Wind vane installation

Slide the wind vane (2) onto the sensor shaft. Tighten the fastening screw with a PH0 screwdriver to make sure the vane is tight in place.

Wind speed sensor installation

Place the wind speed sensor (1) onto the shaft. Tighten the fastening screw. Make sure the wind speed sensor spins freely.

Rain gauge installation

Install the rain gauge funnel (4) and rotate it clockwise to attach to the remote sensor

Batteries installation

Insert 2 AA batteries into the battery compartment (9). The LED indicator (11) on the back of the transmitter blinks every 48 seconds (sensor data transmission refresh period).

ATTENTION! If the LED does not light up or stays on, make sure the batteries are inserted properly and the device is reset correctly. Incorrect installation of batteries may cause permanent damage to the outdoor sensor.

ATTENTION! Alkaline batteries are suitable for most climates, but 1.5V lithium batteries are recommended in cold climates. Rechargeable batteries are not recommended due to their low voltage, instability over a wide temperature range, and short service life, which results in poor signal reception

Mounting the assembled multisensor

Attach the multisensor to the prepared 2.5−5.0cm diameter pipe using U-bolts and a bracket. Align the multisensor in the West direction by rotating it on the mounting pipe. The WEST arrow, located at the top of the multisensor next to the antenna (7), should point due west. Use a compass for fine adjustments. Once oriented correctly, tighten the bolts.

ATTENTION! Check with the bubble level (5), to ensure the multisensor is set up horizontally. The bubble must be completely inside the red circle, otherwise the wind direction and speed, as well as the amount of precipitation may be measured inaccurately. If the bubble is close to the center of the circle, but not completely inside it, and you cannot adjust the mounting pipe, you can place small wood or heavy cardboard wedges between the sensor and the top of the mounting pole to achieve the desired result (this will require loosening the bolts and some experimentation).

Reset button and transmitter LED

If the multisensor is not transmitting data, perform a reset. Press and hold RESET for 3 seconds until the LED (11) lights up. Once the LED lights up, release the button. The LED should resume its normal operation, flashing every 48 seconds

Recommendations for improving wireless connectivity

To avoid radio frequency interference, we recommend that you adhere to the following conditions.

• Place the console several meters away from computer monitors and TVs.
• If you have devices on the 433MHz frequency and are experiencing intermittent connectivity, please unplug them to troubleshoot.
• The maximum range of the device is 100m without, and 30m with obstacles.
• The radio signal does not pass through metal. With metal siding, place the sensor and console so that there is a window between them.

Base station

Open the battery compartment on the back of the console and insert 3 AA batteries into the display console, ensuring correct polarity. Installing the batteries will activate all segments of the weather station՚s LCD display for a few seconds. The weather station will start multisensor registration and the RF (radio frequency) icon will turn on. Do not press the buttons before receiving data from the outdoor multisensor, so as not to interrupt its pairing with the weather station. After registering the sensor, the station automatically switches to normal mode for further setup.

ATTENTION! When replacing the battery in a multisensor, it takes up to 3 hours to re-sync with the weather station. To speed it up, remove and reinstall the weather station batteries. However, this will result in the loss of recorded weather data and alert settings.

Weather station modes

The weather station has six operating modes: normal mode, setup mode, history mode, alert mode, min./max. values, and calibration mode.

Quick display mode

In normal mode press SET to display the following groups of parameters:

• wind/gusts speed;
• amount of precipitation over the last hour/day / week/month / total since the beginning of measurements;
• outdoor temperature/wind chill index/dew point.

Note: While the precipitation total is displayed, press and hold SET for 2 seconds to reset it. To view readings within a group, use the + (2) and MIN/MAX buttons.To return to normal mode, continue to press SET until you exit current mode.

Setup mode

In normal mode, hold SET for 2 seconds to enter setup mode. Use + (2) and MIN/MAX buttons to select values. Press and hold these buttons for more than 2 seconds to speed up switching through functions. Press SET to select the function to be adjusted. Settings order: Time zone > Time format > Manual time and date > Date format > Wind speed units > Wind direction > Precipitation units > Temperature units. Press SET to confirm changes and move on to the next function. Press HISTORY to exit setup mode.

Press SET to accept value changes and move to next sensor. Press HISTORY to exit calibration mode.

Wind speed calibration

The station should be installed away from buildings and trees. Apply a calibration factor if conditions are not ideal. Calibrate using a reference anemometer.

Temperature calibration

Errors may occur when the weather station is close to heat sources or when exposed to direct sunlight without protection. Use a mercury or alcohol thermometer for calibration. Place the sensors nearby in the shade for 48 hours. Compare the readings. Adjust the console according to the temperature of the alcohol/mercury thermometer.

Humidity calibration

The sensor factory error is ±5%. For increased accuracy, calibrate against a reference psychrometer.

Precipitation calibration

The factory calibration is set for 0.01 inches (0.3mm) of precipitation per funnel tipping. To calibrate, install a rain gauge tube of at least 4 inches (10cm) in diameter nearby, compare the readings over 3 rain events and calculate the average deviation. Do not compare values with data from television, radio, newspapers, etc. Such data reflects conditions elsewhere and is not applicable to your area.

History mode

In normal mode press HISTORY to enter history mode. In history mode, press SET to start the archive data clearing procedure. The word CLEAR will start flashing on the screen. Hold SET for 2 seconds to delete all entries. In history mode, press MIN/MAX to select records from the past 24 hours in 3 hour increments.
