
Move the outdoor sensor to a closer location.

Distance/Resistance can cause loss of outdoor sensor signal.

Check Batteries.
Freezer test: Confirm the temperature station is reading the correct outdoor sensor. Place the outdoor
sensor in the freezer for an hour and watch the temperature drop on the temperature station.
Indoor distance test:
Please complete the Restart with outdoor sensor and temperature station 5-10 feet
apart and inside to establish a strong connection.

After 15 minutes, if there is a reading in the outdoor temperature area, move the outdoor sensor to
another room with one wall between the outdoor sensor and the temperature 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 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 indication 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 several hours 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 temperature 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 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 needs to be replaced. Outdoor sensors are water resistant, not waterproof.
