• Move the outdoor sensor to different locations outside to find a location where the
temperature reading will hold.
Outdoor Temperature is stuck or HH.H, LL.L
Explanation: These symbols are error messages indicating the outdoor sensor is outside
of its readable range.
• Check Batteries. Overpowered or underpowered batteries can cause this reading.
• Replace outdoor sensor.
Note: The last outdoor reading may remain (not change) for 30 minutes when connection
is lost. The outdoor temperature reading will flash when the connection is first lost or
intermittent.
Outdoor 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.
• Check the distance and resistance between the outdoor sensor and weather
station. Outdoor sensors at the end of the range may work while batteries are fresh
but not after they drain a bit.
• Check for leaking batteries, which may damage the outdoor sensor.
• Battery life is over 24 months when using reputable battery brands for both Alkaline
and Lithium batteries.
Outdoor Humidity goes to dashes when temperature is cold.
• The outdoor temperature/humidity sensor designed to work with this weather
station may drop the outdoor humidity and dew point reading in cold
temperatures.
• The humidity and dew point will return when the temperature rises. This is how the
sensor came from the factory. The temperature itself will continue to read.
Outdoor sensor fell. The sensor no longer works
Explanation: If there is no physical damage to the outdoor sensor, the fall may not have
caused internal damage. A fall can shock the outdoor sensor or the batteries in the
outdoor sensor. Batteries that have fallen on a hard surface may be damaged and unable
to function properly.
• Complete a Restart with fresh batteries.
• Use Batteries dated at least six years in advance of the current year. Batteries dated
earlier than six years from now may still work, but may be unstable in performance.
Note: An outdoor sensor that has fallen into puddle, snow, or other standing water, will
likely have water damage and need replacement. Outdoor sensors are water resistant, not
waterproof.
