If your AcuRite Atlas® (7-in-1) High Definition Display or My AcuRite® account is displaying the incorrect wind direction, please review the suggestions below.

First, please ensure that the sensor is mounted in the correct orientation. If you are located in the Northern Hemisphere, the center solar panel should be facing South to receive optimal sunlight. 

NOTE: If you are located in the Southern Hemisphere, please refer to the following article instead.

Using the AcuRite Atlas® (7-in-1) Weather Station in the Southern Hemisphere

Check All Connections

We have also determined that the wind direction can read inaccurately if a connection within the sensor is loose or disconnected. Please check that all connections inside the AcuRite Atlas® (7-in-1) sensor are secure.
NOTE: Silicone grease can be added directly to all of the connectors to ensure a more secure connection.

• Wind Assembly Connectors:
  1. Please remove the wind assembly as shown below.
  2. Unplug the connectors, as shown below, for 1-2 minutes.
     
  3. Reconnect the connectors. When re-connecting the assembly plug, you should feel/hear a snap when the connection is 100%.
  4. Reinstall the wind assembly.
     
     
     
• Rain Bucket Connectors
  1. Open your AcuRite Atlas® (7-in-1) sensor by detaching the rain bucket (black portion) from the bottom half of the sensor, as shown below.
  2. Unplug the connectors between the rain bucket and base of the sensor for 1-2 minutes.
  3. Reconnect the connectors. When re-connecting the plug, you should feel/hear a snap when the connection is 100%.
  4. Reassemble the AcuRite Atlas® (7-in-1) sensor by reattaching the rain bucket to the bottom half of the sensor.
     
     
     
• Temperature and Humidity Sensor
  1. On the bottom of the AcuRite Atlas® (7-in-1) sensor, there is a vent cover that is held in place by 2 tabs. Remove the vent.
  2. Under the vent, there is a cylinder that is clipped in with 2 tabs. This is the temperature and humidity sensor. Remove the temperature and humidity sensor to expose the fan.
  3. Unplug the white cable connector and check for corrosion on both ends. If there is corrosion, use a wire brush to clean the connectors. If the temperature and humidity sensor board is corroded, an AcuRite Atlas® Temperature and Humidity Sensor Replacement model #06097M is recommended. 
  4. Reconnect the temperature and humidity sensor's connectors after 1-2 minutes. When re-connecting the sensor assembly plug, you should feel/hear a snap when the connection is 100%.
  5. Install the temperature and humidity board over the fan assembly, confirm the tabs do not block the fan from spinning.

If you have confirmed that your sensor is mounted correctly and all connectors are secure, the wind direction calibration button could have accidentally been bumped during battery installation or other maintenance and will need to be reprogrammed. The following steps can be used to manually reprogram the wind direction.

Correcting The Wind Direction

Perform the following steps to adjust the wind vane orientation:

1. In the battery compartment of the outdoor device, locate the calibration button. Press and hold the calibration button until the red LED begins flashing rapidly.
2. Point the small end of the wind vane to the north. You may need a compass to find the proper north orientation. 
3. While holding the vane facing North, press and hold the calibration button in the battery compartment again until the LED stops flashing rapidly. Wind direction information will now use the new orientation.

If the wind vane is no longer spinning freely:

Ensure wind cups and vane are spinning freely. If they hesitate or stop, try lubricating with graphite powder or spray lubricant. 
To lubricate:

1. 1. Remove the wind vane and cups if possible. If not, you may apply lubricant to the spindle from underneath the vane and cups.
   2. Apply the desired lubricant to the points on the wind assembly shown in the image below:
      
   3. Reinstall wind cups and vane, if removed.
      
      NOTE: The spindle and wind vane can only be reinstalled in one direction. Both the spindle and the hole in the vane are circular-shaped with one flat side. Make sure to line up the flat sides when reinstalling the wind vane. 
      
      If either the wind cups or vane no longer spin freely even after lubrication, we recommend replacing the wind assembly found in the link below.
