Mounting Temperature Sensors

Temperature Sensor Placement/Mounting Instructions

Location of your outdoor temperature sensor is important.

Note:  Temporarily secure sensors in place for a few hours before permanently mounting them, to be sure they will read to your clock or weather station from that location.

Temperature / Temperature-Humidity Sensors

  • Mount the sensor vertically at least 6 feet off the ground.
  • Provide good airflow around the sensor.
  • Direct sunlight can inflate the temperature reading, so a north-side, shaded location is best.
  • If you have a solar panel on the sensor it will need to be charged. Mounting the sensor facing east will allow it to charge with the cooler morning sun.
  • Be aware of heat sources such as soffit or dryer vents, windows or door frames.

 iconSensor Weather Shield - Hard to find a good spot for your sensor?  The Sensor Weather Shield is designed to protect your outdoor temperature/humidity sensor from rain and snow.  This shield will offer limited protection from the sun's heat.  Click here for more information.

IMPORTANT: Some rain and wind sensors transmit to the temperature/humidity sensor and others send directly to the weather station display. Consider the transmission distance to the unit that will receive the signal when choosing a location to mount your sensors. If your sensors are corded, be sure to secure any additional cord from blowing around.

Mounting Rain Sensors

Rain Sensor Placement/Mounting Instructions

Location of your rain sensor is important.

Note:  Temporarily secure sensors in place for a few hours before permanently mounting them, to be sure they will read to your clock or weather station from that location.

 Rain Sensors

  • Mount the sensor at least 6 feet off the ground and make sure it is level.
  • Choose an open area (50 feet all directions) for the most accurate rainfall reading.
  • Rain gauges require regular maintenance to remove leaves, debris and insects. Consider this when choosing a location.
  • While rain sensors cannot measure snowfall, they can be left outside all year long. Remove batteries when not in use.

Daylight Savings Time Questions

Daylight Saving Time

Our Radio Controlled clocks, watches and weather stations receive an embedded radio signal from the Atomic Clock in Ft. Collins, Colorado that tells the product to change to or from Daylight Saving Time. Radio signals are subject to atmospheric and other types of interference. The signal is best received at night.

The antenna in your clock, watch or weather station is directional. It is not unusual for it to take 3-5 nights for signal reception to occur depending on location. Watch antennas are much smaller, so please allow extra time for them to change.

 How can I improve reception?

  • Have good plain alkaline batteries dated 7 years in advance or batteries that have been tested with a voltmeter reading 1.48 or higher. Batteries are the #1 warranty issue we see.
  •  
  • At night, place the clock, watch or weather station on a wall or in a window with the Front or Back facing Ft Collins Colorado. This allows the widest portion of the antenna to be positioned to receive the signal.
  •  
  • Be sure you have the correct Time Zone set on your device. If your clock, watch or weather station is not set to a North American time zone, it may not change for DST.
    • Atlantic - ATL -4
    • Eastern - EST -5
    • Central - CST -6
    • Mountain - MST -7
    • Pacific - PST -8
    • Alaskan - ALA -9
    • Hawaiian - HAW -10
     
  • If your clock, watch or weather station has a DST OFF feature, please be sure to have it turned ON. (Default is ON).
  •  
  • If your clock, or weather station has an ATOMIC OFF, RCC OFF or WWVB OFF feature, please be sure to have it turned ON.

What should I do if the time hasn't changed?

Please allow 3-5 nights for your Clock, Watch or Weather station to correctly change for the start of DST before contacting us. Often it is just an interference issue that will resolve on its own. Product specific information can be found by using the magnifying glass at the top of this screen. If the time has not set after 5 nights, please contact customer support using the below link.

Basic Restart/Missing Outdoor Temperature

Basic Restart

For product specific information enter your model # in the search using the magnifying glass above.

Following is a basic restart procedure for clocks and weather stations that do not have wind or rain:

  • Bring both units inside and have the units 3-5 feet apart with nothing between them.
  • Remove all power from both units.
  • Press one of the buttons on the display at least 20 times to clear all memory. Verify that the display is blank before proceeding.
  • Let all the units sit with batteries out for 10 minutes.
  • Be sure to use a new, Brand Name Alkaline battery dated at least 7 years in advance (super, ultra, max, heavy duty and rechargeable types should be avoided). Place them back into the remote sensor; making sure they are installed according to the diagrams in the battery compartment.
  • Next, taking care not to press any buttons, reinstall the batteries in the display according to the diagram in the battery compartment.
  • Do not press any buttons for at least 15 minutes after installing the batteries. (Let them establish a good connection.)
  • The temperature should be showing on your display. You can now put your sensor back outside.

Side by Side Accuracy Test

Accuracy Test

The best way to test accuracy is with a side-by-side test of the indoor and outdoor unit. All electronics have different tolerances. Comparing a La Crosse Technology sensor to a La Crosse Technology display allows us to test with known tolerances.

Having trouble viewing this video? Click here to view this on YouTube.

CHECK CHANNELS: Some weather stations have a CH or channel button and can pick up a neighbors sensor on a channel that you believe your sensor is on. If your station has a CH or Channel button please press and release that button to determine if you are picking up more than one sensor.

CHECK MIN/MAX MODE: Please check that your display is not stuck in Min or Max mode, which will cause your temperatures to read incorrect.

SIDE-BY-SIDE TEST:

BRING SENSOR TO DISPLAY: Please bring your outdoor transmitter inside and place it beside the display unit (no further that 1-foot away) for at least two hours.

COMPARE: Then compare indoor and outdoor readings; the Temperature difference should be no more than four degrees (+/- 2 degrees) Humidity can be up to 14% difference (+/- 7%).

*If the difference is greater, Place your sensor in the freezer for 20 minutes to be sure you are reading your sensor and not a neighbor's.

*If the sensor reads correctly while next to the display then try a different location outside. Look for heat sources such as sunlight, door or window frames, or reflected heat.  Check for the same things on whatever you are comparing the reading to.

Projection/Backlight will not stay on

Projection/Backlight Function

The projection will be continuously displayed if the AC cord is plugged into the wall.  Please check that the AC cord is properly plugged in. On the unit, line the cord up with the hole and push it in firmly. Sometimes it helps to use a pen, as the opening is small. Once you are sure it is in correctly, remove the batteries. If the display goes blank, your AC cord is not solidly in place.

A unit that has a color display screen or is backlite will remain lite only if the AC cord is plugged into the wall.  If the AC cord is not used the display will stay lite for 5 - 15 seconds and then go dark. 

Product specific information can be found by using the magnifying glass above and searching for your model number.

Why does my outdoor temp come and go?

Outdoor Temperature Troubleshooting

Intermittent temperature readings are generally due to location of the sensor in relation to the indoor display. Following are some things to try.

  • RF (radio frequency) communication may come and go occasionally. This can be normal in some environments (e.g. moister climates). If transmitter signal is lost, please wait 2-4 hours for the signal to reconnect on its own.
  • Move the outdoor transmitter to a closer location.
  • Check channels on the display. The unit may be reading the sensor on a different channel. This can happen if more than one sensor is in the area and the station locks into a distant sensor first.
  • Reorientation of the Indoor display 90 degrees towards the outdoor transmitter may provide better reception
  • Fresh Batteries can often resolve connection issues
  • Freezer test: Confirm the station is reading the correct outdoor transmitter. Place the transmitter in the freezer for an hour and watch the temperature drop on station.

Indoor Distance Test

  • Complete a basic restart with the transmitter and indoor station both inside and 3-6 feet apart to establish a strong connection.
  • After 15 minutes if there is a reading in the outdoor temperature area, move the transmitter to another room with one wall between the transmitter and the Indoor display. Observe to see if the Temperature remains on consistently for 1-hour.
  • If the Temperature remains visible while in the house then it is likely a distance/resistance issue. Move the transmitter to different locations outside to find a location where the Temperature reading will hold.

Distance Considerations

  • Check the maximum transmitting range in open air for your unit on it's product page. Some units are 100-feet (30 meters) between the outdoor transmitter and the Indoor display. Some are over 200-feet (60 meters) open air.
  • Consider what is in the signal path between the Indoor display and the transmitter.
  • Consider the distance the Indoor display is located away from other electronics in the home.

Resistance Considerations

  • Obstacles such as walls, windows, stucco, concrete, and large metal objects can reduce the range.
  • When considering the distance between the transmitter and the Indoor display cut that distance in half for each wall, window, tree, bush or other obstruction in the signal path.
  • Closer is better.
  • Do not mount the transmitter on a metal fence. This significantly reduces the effective range.

Interference Considerations/Sources of Interference

  • Consider items in the signal path between the transmitter and the Indoor display.
  • Sometime a simple relocation of the transmitter or the Indoor station will correct the interference issue.
  • Windows can reflect the radio signal.
  • Metal will absorb the RF (radio frequency) signal.
  • Stucco is held to the wall by a metal mesh, thereby creating interference.
  • Transmitting antennas (ham radio, emergency dispatch center, airports, military base etc.)
  • Electrical wires (utilities, cable etc.)
  • Vegetation is full of moisture and reduces signal.
  • Earth: Trying to receive a signal through a hill is difficult.
