1. Introduction
Thank you for your purchase of the WS2900C-PRO Solar Powered
Wireless WiFi Weather Station. The following user guide provides step
by step instructions for installation, operation and troubleshooting.
2. Warnings and Cautions
Warning: Any metal object may attract a lightning strike, including
your weather station mounting pole. Never install the weather station
in a storm.
Warning: Installing your weather station in a high location may
result in injury or death. Perform as much of the initial check and
operation on the ground and inside a building or home. Only install the
weather station on a clear, dry day.
3. Quick Start Guide
Although the manual is comprehensive, much of the information
contained may be intuitive. In addition, the manual does not flow
properly because the sections are organized by components.

5
The following Quick Start Guide provides only the necessary steps to
install, operate the weather station, and upload to the internet, along
with references to the pertinent sections.
4. Pre-Installation Checkout and Site Survey
4.1 Pre-Installation Checkout
Before installing your weather station in the permanent location, we
recommend operating the weather station for one week in a temporary
location with easy access. This will allow you to check out all the
functions, ensure proper operation, and familiarize you with the
weather station and calibration procedures. This will also allow you to
test the wireless range of the weather station.
4.2 Site Survey
Perform a site survey before installing the weather station. Consider
the following:
1. You must clean the rain gauge every few months and change
the batteries every 2-3 years. Provide easy access to the
weather station.

2. Avoid radiant heat transfer from buildings and structures. In
general, install the sensor array at least 5’ from any building,
structure, ground, or roof top.
3. Avoid any wind or rain obstructions. The rule of thumb is to
install the sensor array at least four times the distance of the
height of the tallest obstruction. For example, if the building is
6m tall, and the mounting pole is 1.8m tall,
Then install 4 x (6 –1.8m) = 17m away.
4. Wireless Range. The radio communication between receiver
and transmitter in an open field can reach up to a distance of
100 meters, providing there are no interfering obstacles such
as buildings, trees, vehicles and high voltage lines. Wireless
signals will not penetrate metal buildings. Under most
conditions, the maximum wireless range is around 50 meters.
5. Radio interference such as PCs, radios or TV sets can, in the
worst case, entirely cut off radio communication. Please take
this into consideration when choosing console or mounting
locations. Make sure your display console is at least five feet
away from any electronic device to avoid interference.

5.2.1 Install U-bolts and mounting pole
Installation of the U-bolts, which are in turn used to mount the sensor
package on a pole, it requires installation of the included metal plate to
receive the U-bolt ends. The metal plate, visible in Error! Reference
source not found.1, has four holes through which the ends of the

8
two U-Bolts will fit. The plate itself is inserted in a groove on the bottom
of the unit (opposite side of solar panel). Note that one side of the plate
has a straight edge (which goes into the groove), the other side is bent
at a 90-degree angle and has a curved profile (which will end up
“hugging” the mounting pole). Once the metal plate is inserted, remove
nuts from the U-Bolts and insert both U-bolts through the respective
holes of the metal plate as shown in Figure 8.
Loosely screw on the nuts on the ends of the U-bolts. You will tighten
these later during final mounting. Final assembly is shown in Figure 9.
The plate and U-Bolts are not yet needed at this stage but doing this
now may help avoid damaging wind vane and wind speed cups
later-on.
Figure 1
Figure 2

5.2.2 Install wind vane
Push the wind vane onto the shaft on the top of the sensor, until it
cannot move further, as shown in figure 3. Tighten the set screw, with
a Philips screwdriver (size PH0), until the wind van cannot be removed
from the axle, as shown in figure 4. Make sure the wind vane will spin
freely. The wind vane’s movement has a small amount of friction, which
is helpful in providing steady wind direction measurements.
Figure 3 Figure 4
There are four alphabet letter of “N”,”E”,”S” and “W” around the wind
direction, representing for the direction of North, East, South and West.
Wind direction sensor has to be adjusted so that the directions on the
sensor are matching with your real location. Permanent wind direction
error will be introduced when the wind direction sensor is not
positioned correctly during installation when the complete WH65
outdoor COMBI unit is facing North. (see clause 5.2.6.2)
5.2.3 Install wind speed
Push the wind speed into the shaft as shown in figure 5.
Tighten the set screw with as shown in figure 5. Make sure the wind
speed can spin freely.

10
Figure 5 Figure 6
5.2.4 Install Rain Gauge
Keep the Indication mark in straight line. As show below photo.
5.2.5 Install Batteries
Insert 2XAA batteries in the battery compartment. The LED indicator on
the back of the transmitter will turn on for four seconds and normally
flash once every 16 seconds (the sensor transmission update period).

11
Figure 7 Figure 8
Note: If no LED lights up or is permanently on, make sure the batteries
are inserted the correct way or a proper reset has happened. Do not
install the batteries backwards. You can permanently damage the
outdoor sensor
Note: We recommend 1.5V lithium batteries for cold weather
climates, but alkaline batteries are enough for most climates. We do
not recommend rechargeable batteries. They have lower voltages, they
do not operate well at wide temperature ranges, and do not last as
long, resulting in poorer reception.
5.2.6 Mount assembled outdoor sensor package WH65
5.2.6.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section,
you may want to skip to setup instructions in section Error!
Reference source not found. and onwards first, while you keep
the assembled outdoor sensor package nearby (although preferably
not closer than 5 ft. from the console). This will make any
troubleshooting and adjustments easier and avoids any distance or
interference related issues with the setup.
After setup is complete and everything is working, return here for
outdoor mounting. If issues show up after outdoor mounting they are
almost certainly related to distance, obstacles etc.

12
5.2.6.2 Mounting
You can attach a pipe to a permanent structure and then attach the
sensor package to it (see Figure 9). The U-Bolts will accommodate a
pipe diameter of 1-2 inches (pipe not included).
Finally, place the sensor package on top of the prepared mounting
pipe. The U-Bolts should be loose enough to allow this but loosen the
nuts as necessary. Once placed, hand tighten all four nuts, taking care
to do so evenly.
Now you will need to align the whole package in the proper direction by
rotating it on top of the mounting pipe as needed. Locate the arrow
labeled “NORTH”that you will find on top of the sensor package right
next to the light sensor. You must rotate the whole sensor package until
this arrow points due north. To achieve proper alignment, it is helpful to
use a compass (many cell phones have a compass application).
Once rotated in the correct orientation, lightly tighten the bolts a little
more (use a wrench) to prevent further rotation.
Note: Use the bubble level next to the rain sensor to make sure sensor
array is completely level. If the sensor is not level the rain gauge UV
and solar radiation sensors will not measure properly.

5.2.7 Reset Button and Transmitter LED
In the event that the sensor array is not transmitting, reset the sensor
array.
With an open-ended paperclip, press and hold the RESET BUTTON
for three seconds to completely discharge the voltage.
Take out the batteries and wait one minute, while covering the solar
panel to drain the voltage.
Put batteries back in and resynchronize with colour console by
powering down and up the console with the sensor array about 3 meter
away.
Figure 11
5.3 Best Practices for Wireless Communication
Note: To ensure proper communication, mount the remote
sensor(s) upright on a vertical surface, such as a wall. Do not lay the
sensor flat.

14
Wireless communications are susceptible to interference, distance,
walls and metal barriers. We recommend the following best practices
for trouble free wireless communication.
Electro-Magnetic Interference (EMI). Keep the console several feet
away from computer monitors and TVs.
Radio Frequency Interference (RFI). If you have other 433 MHz
devices and communication is intermittent, try turning off these other
devices for troubleshooting purposes. You may need to relocate the
transmitters or receivers to avoid intermittent communication.
1. Line of Sight Rating. This device is rated at 100 meters line of
sight (no interference, barriers or walls) but typically you will get
50 meters maximum under most real-world installations, which
include passing through barriers or walls.
2. Metal Barriers. Radio frequency will not pass through metal
barriers such as aluminum siding. If you have metal siding,
align the remote and indoor console through a window to get a
clear line of sight.
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

Glass (untreated)
5-15%
Plastics
10-15%
Wood
10-40%
Brick

5.4 Display console
1. Insert the 5V AC certified power adaptor into the back of the display
console
Note: Place the outdoor sensor array about 5 to 10 feet from the
display console and wait several minutes for the remote sensors to
synchronize with the display console.
2. Insert 3 AAA batteries into the display console。Please insert the
batteries as in the figure 12 below:
Figure 12
Note: The batteries are intended for back-up power only. The
backlight will remain on for 5 seconds when on back up battery
power only. Only when you use the power adapter the back-light
will be continuously on.
3. Keep both sensor and the display console together for 15 minutes
to lock in the sensor signals.
4. Spin the wind cups to simulate wind speed. Take the sensor to the
sink and slowly drip water into the rain bucket to simulate rain.
5. After 15 minutes, follow the mounting instructions for the proper

16
placement of sensors.
Figure 13
Note: Your display console should have readings in all sections. Wind
and Rain will show 0’s (connected) until wind or rain occur or are
simulated.
Note: If you only use battery to power up display console, you must
press LIGHT/SNOOZE key to light up the LCD before pressing any
other key.
5.4.1 Vertical Desk Stand
The console is best viewed above from a 20 to 30 degree angle.
In addition to the fold out desk stand on the back of the display console
it also includes a vertical desk stand to improve viewing on a desk, as
