1. Introduction
Thank you for your purchase of the WN30BN probed thermometer. The following user guide provides
step by step instructions for installation, operation and troubleshooting.
The sensor is not a stand-alone device, and requires a WS-290B (or greater revision), WS-2000 or
WS-5000 weather station to view and upload the data to our cloud hosting service.
2. Features
10’water-proof probed thermometer
Long wireless range up to 330 feet (100 meters) in open areas
Transmits readings approximately once per minute.
Suspension eye for easy mounting

4. Setup Guide
4.1 Batteries and Dip Switches
The WN30BN probed thermometer requires 2 x AA batteries (not included). We recommend
Energizer Lithium batteries for longer life and a wider operating temperature range.
1. Remove the battery door on the back of the transmitter(s) by sliding down the battery door, as
shown in Figure 2 .
Figure 2
2. BEFORE inserting the batteries, locate the dip switches on the inside cover of the lid of the
transmitter.
3. Channel Number: The WS-2000 and WS-5000 supports up to eight transmitters. To set each

Page 3
channel number (the default is Channel 1), change Dip Switches 1, 2 and 3, as referenced in
Figure 3.
4. Temperature Units of Measure: To change the transmitter display units of measure (°F
vs. °C), change Dip Switch 4, as referenced in Figure 3.
Switch in down position. Switch in up position.
Figure 3
5. Insert two AA batteries.
6. Verify the correct channel number (CH) and temperature units of measure (°F vs. °C) are on
the display, as shown in Figure 4.

7. Close the battery door.
8. Repeat for the additional remote transmitters, verifying each remote is on a different channel.
5. Sensor Placement
To mount or hang the sensor:

Page 4
Use a screw or nail to affix the remote sensor to the wall, as shown in Figure 5 (a) or
Hang the sensor using a string or zip tie, as shown in Figure 5 (b).

Note: Make sure the sensor is mounted vertically and not lying down on a flat surface. This will
insure optimum reception. Wireless signals are impacted by distance, interference (other weather
stations, wireless phones, wireless routers, TVs and computer monitors), and transmission barriers,
such as walls. In general, wireless signals will not penetrate solid metal and earth (down a hill, for
example).
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.
Medium
RF Signal Strength Reduction
Glass (untreated)
5-15%
Plastics
10-15%
Wood
10-40%
