Thermohygro Transmitter Drains Batteries Quickly; Outdoor Temperature/Humidity Is Stuck Or Ofl; Thermohygro Transmitter Stops Working When Hot; Humidity Shows Ofl But Temperature Works - La Crosse Technology WS-1517 Faqs

 Transmitters are water resistant, not waterproof.
 A fall can shock the transmitter or the batteries in the transmitter.
 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.

Thermohygro transmitter 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. This is helpful in determining the
problem.
 Check the
distance and resistance between the transmitter and weather station. Transmitters 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 transmitter.

Outdoor temperature/humidity is stuck or OFL

 Check
Batteries. Overpowered or underpowered batteries can cause this reading.
 Replace outdoor transmitter.

Thermohygro transmitter stops working when hot

Thermohygro transmitters show Dashes or OFL when the temperature reaches a certain degree, but
returns to normal readings when the temperature cools down; please check:

BATTERIES: At higher temperatures, batteries can overheat causing transmitter failure. Older and
weaker batteries are more likely to fail in hot weather. Try a fresh set of
is resolved.

DISTANCE/RESISTANCE: When the Thermohygro transmitter is at the edge of the
and the temperatures are very hot, the batteries can loose strength and the connection may be lost.

Humidity shows OFL but temperature works

 Complete a restart with fresh batteries.
 Replace the thermohygro transmitter.

Fahrenheit/Celsius

 With temperature and humidity icon flashing, hold the SET button to alternate between temperature in
Fahrenheit (ºF) or Celsius (ºC).

Temperature alerts

Set Temperature Alarm
1. With temperature and humidity icon flashing, press and release the ALARM/CHART button once
selecting the desired alarm limit–-Upper or Lower.
2. Hold the ALARM/CHART button until the temperature alarm icon starts flashing.
3. Use the UP or DOWN arrows to select the temperature alarm value. Press and hold either button for
fast digits advance.
4. Press the ALARM/CHART button to confirm selection and return to the temperature Alarm selection
screen.
Note: The temperature alarms have a 1°F (0.5ºC) deviation to prevent false alarms due to small
temperature fluctuations. Temperature has to fall below (or above) the programmed level(s) to
activate the alert.
Disable the Temperature Alarm
1. With temperature and humidity icon flashing, press and release the ALARM/CHART button once to
select the high or low temperature alarm.
