GENERAL INFORMATION
BATTERIES: WHAT DO I NEED TO KNOW ABOUT BATTERIES?
•
Good fresh batteries are important for best performance in your sensor and as backup in
your station.
•
Batteries are manufactured 10 years in advance of the date on the battery.
•
We recommend batteries with an expiration date no more than 6 years in advance of the
current year for best performance.
•
A minimum voltage of 1.48 v per battery is required for best performance.
•
Lithium batteries may be used in outdoor sensor. Alkaline batteries for the station.
HARDWARE: SENSOR AND STATION
Your WS-9023U-IT station comes with:
TX21U-IT Thermo-hygro sensor that reads Temperature and Humidity.
Your sensor operates at 915MHz RF.
Transmission range is 330 feet (100 meters) open air.
WHAT ARE THE POWER REQUIREMENTS FOR THIS STATION?
TX21U-IT: 2-AA batteries
WS-9023U-IT: 2-AA batteries
SETUP: HOW DO I SETUP MY STATION?
1.
Install batteries into your sensor.
2.
Install batteries into the station.
3.
Let sensor and station sit within 10 feet of each other for several minutes to lock the sensor
signals to the display.
MOUNTING: WHERE DO I MOUNT/POSITION MY SENSOR?
TX21U-IT:
•
Place your thermo-hygro sensor at least 6 feet off the ground.
•
For accurate temperature readings your sensor needs to be shaded from the sun in a well
vented area.
•
Mount your sensor vertically to allow moisture to drain out the bottom.
•
Preferred location is on a north facing wall under an eave or deck rail.
•
Avoid placing near a metal roof that will cause it to read high on sunny days.
•
Avoid other sources of heat such as soffit vents, and window or door frames.
•
For accurate humidity readings, avoid placement near vegetation and lakes or other bodies
of water when possible.
•
Place your sensor in a well-vented area. Trapped moisture will cause inaccurate readings.
•
Maximum transmission distance from your thermos-hygro sensor to your station, in open air
is 330 feet (100 meters).
