•
Dashes means the unit have lost connection between the display and the outdoor
sensor.
•
Batteries are the most common problem.
•
Distance/Resistance can cause loss of sensor signal. Avoid having more than 1 wall,
window, tree etc., between the display and your sensor. UV coated windows may
actually reflect the signal. Stucco walls will absorb the signal.
•
It may be helpful to orient the weather 90 degrees towards your sensor for better
reception.
•
Sensors operate best when elevated at least 6 feet.
•
Remove the batteries from your sensor for 2 minutes. Replace the batteries in the
Thermohygro sensor and after 5 minutes press and hold the SEARCH button for 5
seconds. Wait 10 minutes. If the unit does not receive a reading from all your sensors,
please try the
INACCURATE OUTDOOR TEMPERATURE/HUMIDITY
•
The thermo-hygro sensor reads the environment. When one of your sensors reads
high during the day but not at night it is often a mounting problem.
•
Side-by-side test: Bring the thermo-hygro sensor in the house and place it next to
your station for 2 hours.
•
Alternatively, place your inaccurate sensor right next to a working sensor for 2
hours.
•
Compare temperatures. The temperatures should be within 4 degrees to be within
tolerance. The humidity should be within 14% to be within tolerance.
•
If your sensor reads correctly when next to your station then try a different location
outside.
•
Look for heat sources such as sunlight, door or window frames, or reflected heat.
OUTDOOR READINGS ARE STUCK OR HI OR LO
•
Check batteries. Overpowered or underpowered batteries can cause this reading.
•
Replace sensor.
INTERMITTENT SENSOR READINGS
•
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 the signal is lost, the RX will display the LAST DATA recorded from sensor for 10
minutes.
•
After that 10 minutes if the signal does not come back then display dashes "--".
•
After 30 minutes, start looking for the RF signals automatically.
If a miss happens:
