1 Introduction
Thank you for your purchase of this 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 Pre-Installation Checkout and Site Survey
3.1 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 of the
functions, ensure proper operation, and familiarize yourself with the weather
station and calibration procedures. This will also allow you to test the
wireless range of the weather station.
3.2 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 1 year. 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,

4
or rooftop.
3. Avoid wind and 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 20’ tall, and the mounting
pole is 6’ tall, install 4 x (20 – 6)’ = 56’ away.
4. Wireless Range. The radio communication between receiver and
transmitter in an open field can reach a distance of up to 100 meters,
providing there are no interfering obstacles such as buildings, trees,
vehicles, or high voltage lines. Wireless signals will not penetrate metal
buildings. Under most conditions, the maximum wireless range is 100
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.

4.2.1 Install U-bolts and mounting pole
Installation of the U-bolts, which are in turn used to mount the sensor
package on a pole, requires installation of an included metal plate to receive

6
the U-bolt ends. The metal plate, visible in Figure 2, has four holes through
which the ends of the two U-Bolts will fit. The plate itself is inserted in a
groove on the bottom of the unit. 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 2.
Figure 2: U-Bolt installation
Loosely screw on the nuts on the ends of the U-bolts. You will tighten these
later during the final mounting. The final assembly is shown in Figure 3.
Figure 3: U-Bolts and nuts installed
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.

7
4.2.2 Install wind vane
Push the wind vane onto the shaft on the bottom of the sensor, until it stops
moving further, as shown in figure 4.
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 spins freely. The wind vane’s movement has a small amount of
friction, which is helpful in providing steady wind direction measurements.
Figure 4: Wind vane installation diagram
4.2.3 Install wind speed
Push the wind speed into the shaft as shown in figure 5.
Tighten the set screw with a screwdriver. Make sure the wind speed can spin
freely.
Figure 5: Wind speed cup installation diagram

8
4.2.4 Install Rain Gauge
Install the rain gauge funnel. Rotate clockwise to attach the funnel to the
outdoor sensor.
Figure 6: Rain gauge installation and maintenance
4.2.5 Install Batteries
Insert 2 AA 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).

9
Figure 7: Battery installation diagram
Note: If no LED light 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 backward. 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 range, and do not last as long, resulting in poorer
reception.
4.2.6 Mount assembled outdoor sensor package
4.2.6.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section, you
may want to skip to setup instructions in section 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 instance or interference related issues
from 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.

10
4.2.6.2 Mounting
You can attach a pipe to a permanent structure and then attach the sensor
package to it (see Figure 8). The U-Bolts will accommodate a pipe diameter
of 1-2 inches (pipe not included).
Figure 8: Sensor package mounting diagram
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 nece
ssary.
Once placed, the hand tightens 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 “WEST” 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 West. 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 the sensor
array is completely level. If the sensor is not level then the rain gauge will
measure inaccurately.

11
4.2.7 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 and resynchronize with the console by powering down and up
the console. Please put the console with the sensor array about 3 meters
away.

6 Maintenance
The following steps should be taken for proper maintenance of your station.

12
1. Clean the rain gauge once every 3 months. Rotate the funnel
counter-clockwise and lift to expose the rain gauge mechanism, and
clean with a damp cloth. Remove any dirt, debris and insects. If bug
infestation is an issue, spray the array lightly with insecticide.
Figure 10: Rain gauge installation and maintenance
2. Replace batteries every 1-2 years. If left in too long, the batteries may
leak due to environmental challenges. In harsh environments, inspect the
batteries every 3 months.
3. When replacing the batteries, apply a corrosion-preventing compound
on the battery terminals, available at Amazon and most hardware stores.
4. In snowy environments, spray the top of the weather station with
anti-icing silicon spray to prevent snow build-up.
7 Troubleshooting Guide
Look through the following and locate an issue or problem you are
experiencing in the left column and read possible solutions in the right
column.

13
Problem
Solution
The outdoor sensor
array does not
communicate with the
display console..
The sensor array may have initiated properly and
the data is registered by the console as invalid,
and the console must be reset. Press the reset
button as described in Section 5.2.
With an open-ended paperclip, press the reset
button for 3 seconds to resync the console with
the sensor array about 10 feet away.
The LED next to the battery compartment will
flash every 16 seconds. If the LED is not
flashing every 16 seconds…
Replace the batteries in the external sensor array.
If the batteries were recently replaced, check the
polarity. If the sensor is flashing every 16
seconds, proceed to the next step.
There may be a temporary loss of
communication due to reception loss related to
interference or other location factors,
or the batteries may have been changed in the
sensor array and the console has not been reset.
The solution may be as simple as powering
down and up the console (remove the AC power
and batteries, wait 10 seconds, and reinsert AC
power and batteries).
The temperature
sensor reads too high
in the daytime.
Make sure the sensor array is not too close to
heat-generating sources or strictures, such as
buildings, pavement, walls, is air conditioning
units.Use the calibration feature to offset
installation issues related to radiant heat sources.
Reference Section 10.6.
The rain gauge reports
An unstable mounting solution (sway in the

14
rain when it is not
raining
mounting pole) may result in the tipping bucket
incorrectly incrementing rainfall. Make sure you
have a stable, level mounting solution.
