Inaccurate Remote Temperature Reading
Explanation:
High remote temperature readings are generally a location issue. Low remote temperature
readings are power related or a sensors going bad.
 The remote sensor reads the environment where it is mounted. When mounted inside the home, it will
read inside temperature/humidity.
 When the remote sensor reads high during the day, but not at night, it is a positioning problem.
 Look for heat sources such as sunlight, door or window frames or reflected heat.
Side-by-side test:
Place the remote sensor right next to the weather station for 2 hours.
 Compare indoor and remote temperature. The temperatures should be within 4 degrees to be within
tolerance.
 If the remote sensor reads correctly when next to the weather station, try a different location outside.
Intermittent Remote Temperature
Explanation:
Intermittent problems are the hardest to resolve. RF (radio frequency) communication may
come and go occasionally. This can be normal in some environments (e.g. moister climates). If remote
sensor signal is lost, please wait 2-4 hours for the signal to reconnect on its own.
 Move the remote sensor to a closer location.
 Distance/Resistance can cause loss of remote sensor signal.
 Check Batteries.
Freezer test:
Confirm the weather station is reading the correct remote sensor (not a neighbor’s sensor).
Place the remote sensor in the freezer for an hour and watch the temperature drop on the weather station.
Indoor distance test:
Please complete the Restart with remote sensor and weather station 5-10 feet apart
and inside to establish a strong connection.
 After 15 minutes, if there is a reading in the remote temperature area, move the remote sensor to
another room with one wall between the remote sensor and the weather station.
 Observe to see if the temperature remains on consistently for 1 hour.
 If the temperature remains on while in the house, then it is likely a distance/resistance issue.
 Move the remote sensor to different locations outside to find a location where the temperature reading
will hold.
Remote Temperature is stuck or HH.H, LL.L
Explanation:
These symbols are error messages indicating the remote sensor is outside of its readable
range.
 Check Batteries. Overpowered or underpowered batteries can cause this reading.
 Replace remote sensor.
Note:
The last remote reading may remain (not change) for several hours when connection is lost. The
remote temperature reading will flash when the connection is first lost or intermittent.
Remote sensor drains batteries quickly
 Test a new set of alkaline batteries. Write down the date of installation and the voltage of the batteries.
 When the batteries fail, please note the date and voltage again.
