Remote Transmitters
Power requirements
2-AAA batteries power the Thermohygro transmitter
2-AA batteries for the Rain transmitter
2-AA batteries for the Wind transmitter
We recommend Alkaline
batteries
for the transmitters.
You may choose to use lithium batteries for temperatures below 32°F (0°C).
Compatible outdoor transmitters
TS21 Thermohygro
TS805 Wind
TS906 Rain
The above 433MHz transmitters will read to this weather station.
Dashes shown for outdoor temperature/humidity
Dashes means the connection is lost between the weather station and the outdoor transmitter.
Batteries
often resolve the connection.
Distance/Resistance
can cause loss of connection between the transmitter and the weather station.
Reorientation of the weather station 90 degrees towards the thermohygro transmitter may provide
better reception by the antenna.
Complete a
factory restart
.
Inaccurate outdoor temperature/humidity
The thermohygro transmitter reads the environment. When the transmitter reads high during the day
but not at night it is a
mounting
problem.
Side-by-side test:
Bring the thermohygro transmitter in the house and place it next to the weather
station for 2 hours.
Compare indoor and outdoor temperature. The temperatures should be within 4 degrees to be within
tolerance. The humidity should be within 10% to be within tolerance.
If the transmitter reads correctly when next to the weather station, try a different location outside.
Look for heat sources such as sunlight, door or window frames, or reflected heat.
Intermittent outdoor temperature/humidity
RF (radio frequency) communication may come and go occasionally. This can be normal in some
environments (e.g. moister climates). If transmitter signal is lost, please wait 2-4 hours for the signal
to reconnect on its own.
Move the remote transmitters to a location closer to the weather station.
Indoor distance test:
Please complete the
Restart
with transmitters and weather 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 transmitter to another
room with one wall between the transmitter and the weather station. Observe to see if the remote
readings remain on consistently for 1 hour.
If the remote reading remains on while in the house then it is likely a
distance/resistance
issue.
Move the transmitter to different locations outside to find a location where the remote readings will
hold.
Distance/Resistance
can cause loss of transmitter signal.

Thermohygro transmitter fell, and does not work
The fall may not have caused internal damage if there is no physical damage.
A thermohygro transmitter that has fallen into a puddle or other standing water or snow may have
water damage.
