V61 / C75716 Troubleshooting the Rain Sensor (LTV-R3)

Why Does My Rain Reading Show 0.00 When It Is Raining?

Your Rain Sensor will show 0.00 when it loses connection. 24 hours after it loses connection to the station, you will see DAYS WITHOUT RAIN appear.

• Check that your Rain Sensor Reception Icon  is present.  
• If it is not Hold the Rain button to search for your rain sensor.
• Check that your Batteries are good and that, Distance, Resistance, and Interference are not causing signal loss.

Why Does My Rain Reading Show "Days Since Last Rain" When It Is Raining?

When new rainfall is counted your DAYS WITHOUT RAIN will immediately switch to the last rainfall unit (1 hour, 24 hour etc.) that you previously selected.  If this does not happen, you have lost connection to your Rain sensor.

Your Rain Sensor will show 0.00 when it loses connection. 24 hours after it loses connection to the station you will see DAYS WITHOUT RAIN appear.

• Check that your Rain Sensor Reception Icon is present.
• If it is not Hold the Rain button to search for your rain sensor.
• Check that your Batteries are good and that, Distance, Resistance, and Interference are not causing signal loss.

Rain Intermittent:  Why Do My Readings Come and Go?

• RF (radio frequency) communication may come and go occasionally. This can be normal in some environments (e.g., moister climates). 
• If a sensor goes out, please wait 2-4 hours for it to reconnect on its own. Please be patience – these stations can reconnect on, after many hours out.
• RF (radio frequency) communication is not always 100% on. Certain temporary conditions can cause it to go out for a time (e.g., 100% humidity). 

 If a miss happens:

• If your rain sensor loses connection to your station for any reason, the station will show dashes after 30 minutes.
• The station will search for 5 minutes every hour to reconnect with rain sensor.
• Be sure you have good batteries. Manually search for your sensor.

Try this:

• Bring your rain sensor within 10 feet of your station and make sure it is connected to the station. Your station will show 0.00 for rain when connected and no rain has occurred.
• After 15 minutes move the rain sensor into the next room with a wall between the sensor and the station for 1 hour.
• If there is no loss of signal in that hour, move the rain sensor just outside.
• Continue moving the rain sensor back to its original location.
• If you lose connection, look for sources of interference.

Rain Low:  Why Is My Rainfall Reading Low?

• Low rain readings indicate the rain sensor and station are connected.
• Check that the rocker tips freely.
• Check the funnel and the inside of the rain sensor for insect nests or debris that may cause loss of rocker motion.
• Be sure to mount the rain sensor level.

Complete a Tip Test:

Write down the Total Rain reading or reset the Rain Total to 0.00. With rain sensor mounted slowly pour water into the funnel to tip the rocker of the rain sensor 10 times. Wait at least 2 minutes for all the rain to collect. Repeat three times.

• Compare these tests. If they are the same, then your rain is reading correctly. If the rain readings are different, repeat the test 3 times to avoid human error. Then look for causes such as mounting too tight or debris clogging the funnel.

Rain High:  Why Is My Rainfall Reading High?

• Check for sources of RF (radio frequency) interference such as other wireless rain sensors, ham radios or electric transformers.
• Keep the station six feet from cordless phones or wireless routers etc.

Complete a Tip Test:

Write down the Total Rain reading or reset the Rain Total to 0.00. With rain sensor mounted slowly pour water into the funnel to tip the rocker of the rain sensor 10 times. Wait at least 2 minutes for all the rain to collect. Repeat three times.

• Compare these tests. If they still read high then contact support.

How Can I Clean My Rain Sensor?

1. Remove rain funnel (open locking tabs on both sides and pull off funnel)
2. Gently remove debris or insects inside the rain
3. Clear debris from drain
4. Clear debris from the rain
5. Reinstall the rain

Note: Do not oil the rain sensor.

What Can I Do With My Rain Sensor in the Winter?

• Your Rain Sensor and all your sensors are designed to be outside all year around.
• Since your Rian Sensor cannot accurately count snowfall, many people choose to cover it in the winter, or take it down, remove the batteries and store it until spring.
