5.Set up Guide
5.1 Pre Installation Checkout
To complete assembly you will need a Philips screwdriver (size PH0) and a
wrench (size M5; included in package).
Before installing the weather station on the place of operation, we recommend
placing the weather station at a temporary location with easy access for one
week. This will let you check all functions, ensure proper operation, and get
familiar with the weather station and its calibration procedures. During this
time, you can also test the wireless range between the main unit and the
integrated wireless sensor.
Attention:
Follow suggested order for battery installation (outdoor sensor first,
console second)
Ensure batteries are installed with correct polarity (+/-)
Do not mix old and new batteries
Do not use rechargeable batteries
If outdoor temperature may go below 32F or 0C for prolonged periods,
Lithium based batteries are suggested over alkaline type batteries for the
outdoor sensor array
5.2 Site Survey
Perform a site survey before installing the weather station. Consider the
following:
1. Avoid radiant heat transfer from buildings and structures. In general,
install the sensor array at least 5’ or 1.52m from any building,
structure, ground, or roof top.
2. 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
Page 11
11
obstruction. For example, if the building is 20’ or 6.10m tall and the
mounting pole is 6’ or 1.83m tall, install the sensor array 4 x (20 – 6)’
= 56’ or 4 x (6.1-1.83)=17.08m away.
3. Installing the weather station over sprinkler systems or other
unnatural vegetation may affect temperature and humidity readings.
We suggest mounting the sensor array over natural vegetation.
4. Radio Interference. Computers, radios, televisions and other sources
can interfere with radio communications between the sensor array
and console. Please take this into consideration when choosing
console or mounting locations. Make sure your display console is at
least five feet or 1.52 meter away from any electronic device to avoid
interference.
5.3 Outdoor Sensor Package Assembly
5.3.1 Install U-bolts and metal plate
Slide the U-bolts into the metal plate on the underside of the integrated
wireless sensor and screw the nuts from the other side so that the bar on which
the integrated wireless sensor is placed can be inserted into this hole.
Figure 4: U-Bolt installation
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. Handling of the
sensor package with wind vane and speed cups installed to install these bolts
is more difficult and more likely to lead to damage.
Page 12
12
5.3.2 Install wind vane
Push the wind vane onto the shaft on the top side of the sensor package, until
it goes no further, tighten the set screw, with a Philips screwdriver (size PH0).
Make sure the wind vane can rotate freely. The wind vane’s movement has a
small amount of friction, which is helpful in providing steady wind direction
measurements.
Figure 5: Wind vane installation diagram
The wind direction section on the main unit display shows the letters N
(North), E (East), S (South) and W (West). The integrated wireless
sensor must be oriented so that the arrow marked “North” on the top
of the wireless sensor is pointing north. If the integrated wireless
sensor is oriented incorrectly, wind direction measurement will be
inaccurate.
5.3.3 Install wind speed cups
Push the wind speed cup assembly onto the shaft on the top side of the sensor
package, Tighten the set screw, with a Philips screwdriver (size PH0). Make
sure the cup assembly can rotate freely. There should be no noticeable friction
when it is turning.
Page 13
13
Figure 6: Wind speed cup installation diagram
5.3.4 Install the Rain Gauge Funnel
Rotate clockwise to attach the funnel to the sensor array.
Figure 7: Rain Gauge Funnel installation diagram
5.3.5 Install Batteries in sensor package
Open the battery compartment and insert 2 AA batteries in the battery
compartment. The LED indicator on the back of the sensor package will turn
on for 4 seconds and then flash once every 16 seconds indicating sensor data
transmission.
Page 14
14
Figure 8: Battery installation diagram
Note: If LED does not light up or is on permanently, make sure the battery
is inserted the correct way and inserted fully, starting over if
necessary. Do not install the batteries backwards as it may
permanently damage the outdoor sensor.
Note: We recommend Lithium batteries for cold weather climates, but
alkaline batteries are sufficient for most climates. Rechargeable
batteries have lower voltages and should never be used.
5.3.6 Mount assembled outdoor sensor package
Install the integrated wireless sensor in an open space, away from obstacles
such as other buildings, trees, etc. that prevent free wind flow, to ensure
undistorted measurements of individual weather elements. Point the part with
the vane and propeller north for correct wind direction measurement. Place
the integrated wireless sensor onto the stand (not included) at a minimum
distance of 1.5 metres from the ground to prevent the measured values being
affected by the ground surface and tighten the bolts. Use the spirit level on the
top of the integrated wireless sensor to ensure that it is level. Tighten the
U-bolt nuts.
Page 15
15
Figure 9: Sensor package mounting diagram
.
Note: If you tested the full assembly indoors and then came back here for
instructions and mounted to sensor package outdoor you may want to
make some further adjustments on the console. The transportation
from indoor to outdoor and handling of the sensor is likely to have
“tripped” the rainfall sensing bucket one or more times and
consequently the console may have registered rainfall that did not
really exist. You can use console functions to clear this from history.
Doing so is also important to avoid false registration of these readings
with weather services..
5.3.7 Reset Button and Transmitter LED
In the event the sensor array is not transmitting, reset the sensor array.
Using a bent-open paperclip, press and hold the RESET BUTTON (see
Figure 0) to affect a reset: the LED turns on while the RESET button is
depressed, and you can now let go. The LED should then resume as normal,
flashing approximately once every 16 seconds.

5.4 Indoor Sensor Set Up
Note: To avoid permanent damage, please take note of the battery polarity
before inserting the batteries.
Remove the battery door on the back of the sensor. Insert two AA batteries.
Figure 11: Indoor sensor battery installation
Page 17

5.5 Multi-channel temperature and humidity sensor
(Optional)
The HP2550 supports up to 8 additional thermo-hygrometer sensors (WH31),
which can be viewed on the display tablet and Internet.
Note: Do not use rechargeable batteries. We recommend fresh alkaline
batteries for outdoor temperature ranges between -10 °C and 60 °C and fresh
lithium batteries for outdoor temperature ranges between -40 °C and -10 °C.
5.5.1 Install batteries
1. Remove the battery door on the back of the transmitter(s) by sliding
down the battery door, as shown in Figure 2 .
Figure 12: Battery installation for Multi-channel sensor
2. BEFORE inserting the batteries, locate the dip switches on the
inside cover of the lid of the transmitter.
3. Channel Number: The device supports up to eight sensors. To set
each channel number change Dip Switches 1, 2 and 3, as
referenced in Figure .
4. Temperature Units of Measure: To change the transmitter display
units of measure (°F vs. °C), change Dip Switch 4, as referenced in
Page 18

Repeat for the additional remote transmitters, verifying each remote is on a
different channel.
5.5.2 Sensor Placement
The best mounting location for the indoor sensor is in a location that never
receives direct sunlight, not even through windows. Also, do not install in a
location where a nearby radiant heat source (radiator, heaters, etc.) will affect
it. Direct sunlight and radiant heat sources will result in inaccurate
temperature readings.
The sensor is meant to provide indoor conditions for display on the console,
but if you would rather have a second source for outdoor conditions instead,
you can mount this unit outside. Recommend to mount the unit under cover
(eve or awning or similar).
To mount or hang the unit on a wall or wood beam:
Use a screw or nail to affix the remote sensor to the wall, as shown on the
left side of Figure 1, or
Hang the remote sensor using a string, as shown in right side of Figure 1
Figure 15: Indoor sensor mounting
Note: Make sure the sensor is mounted vertically and not lying down on a
flat surface. This will insure optimum reception.
Page 20

5.6 Best Practices for Wireless Communication
Wireless (RF) communication is susceptible to interference, distance, walls
and metal barriers. We recommend the following best practices for trouble
free wireless communication between both sensor packages and the console:
Indoor sensor placement: The sensor will have the longest reach for its
signal when mounted or hung vertically. Avoid laying it down on a flat
surface.
Electro-Magnetic Interference (EMI). Keep the console several feet
away from computer monitors and TVs.
Radio Frequency Interference (RFI). If you have other devices
operating on the same frequency band as your indoor and/or outdoor
sensors and experience intermittent communication between sensor
package and console, try turning off these other devices for
troubleshooting purposes. You may need to relocate the transmitters or
receivers to avoid the interference and establish reliable communication.
The frequencies used by the sensors are one of (depending on your
location): 433, 868, or 915 MHz (915 MHz for United States).
Line of Sight Rating. This device is rated at 300 feet line of sight (under
ideal circumstances; no interference, barriers or walls), but in most
real-world scenarios, including a wall or two, you will be able to go about
100 feet.
Metal Barriers. Radio frequency will not pass through metal barriers
such as aluminum siding or metal wall framing. If you have such metal
barriers and experience communication problems, you must change the
placement of sensor package and or console.
The following table shows different transmission media and expected signal
strength reductions. Each “wall” or obstruction decreases the transmission
range by the factor shown below.

Note: If you are testing the setup with the outdoor sensor package nearby
and indoor, you may want to consider connecting to Wi-Fi, but not yet
configuring any of the weather services. The reason is that while indoor the
temperatures and humidity recorded by the outdoor sensor, and as reported
to the weather service(s) will reflect indoor conditions, and not outdoor
conditions. Therefore, they will be incorrect. Furthermore, the rainfall
bucket may be tripped during handling, causing rain to register while it may
not actually have been raining. One way to prevent this is to follow all
instructions, except to use an incorrect password, on purpose! Then, after
final outdoor installation, come back and change the password after clearing
console history. That will start uploading to the services with a clean slate.

(1) Temperature errors can occur when a sensor is placed too close to a
heat source (such as a building structure, the ground or trees).
To calibrate temperature, we recommend a mercury or red spirit
(fluid) thermometer. Bi-metal (dial) and digital thermometers (from
other weather stations) are not a good source and have their own
margin of error. Using a local weather station in your area is also a
poor source due to changes in location, timing (airport weather
stations are only updated once per hour) and possible calibration
errors (many official weather stations are not properly installed and
calibrated).
Place the sensor in a shaded, controlled environment next to the fluid
thermometer, and allow the sensor to stabilize for 3 hours. Compare
this temperature to the fluid thermometer and adjust the console to
match the fluid thermometer.
(2) Humidity is a difficult parameter to measure electronically and drifts
Page 64
64
over time due to contamination. In addition, location has an adverse
affect on humidity readings (installation over dirt vs. lawn for
example).
Official stations recalibrate or replace humidity sensors on a yearly
basis. Due to manufacturing tolerances, the humidity is accurate to
± 5%. To improve this accuracy, the indoor and outdoor humidity can
be calibrated using an accurate source, such as a sling psychrometer.
(3) The display console displays two different pressures: absolute
(measured) and relative (corrected to sea-level).
To compare pressure conditions from one location to another,
meteorologists correct pressure to sea-level conditions. Because the
air pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be at if located at sea-level)
is generally higher than your measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an
altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg
(1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the
average sea-level pressure around the world. Relative pressure
measurements greater than 29.92 inHg (1013 mb) are considered high
pressure and relative pressure measurements less than 29.92 inHg are
considered low pressure.
To determine the relative pressure for your location, locate an official
reporting station near you (the internet is the best source for real time
barometer conditions, such as Weather.com or Wunderground.com),
and set your weather station to match the official reporting station.
Page 65
65
(4) Only use this if you improperly installed the weather station sensor
array, and did not point the direction reference to true north.
(5) The default conversion factor based on the wavelength for bright
sunlight is 126.7 lux / w/m2 . This variable can be adjusted by
photovoltaic experts based on the light wavelength of interest, but for
most weather station owners, is accurate for typical applications, such
as calculating evapotransporation and solar panel efficiency.
(6) Wind speed is the most sensitive to installation constraints. The rule
of thumb for properly installing a wind speed sensor is 4 x the
distance of the tallest obstruction. For example, if your house is 20’
tall and you mount the sensor on a 5’ pole:
Distance = 4 x (20 – 5)’ = 60’ or =4 x (6.10-1.52)=18.32m.
Many installations are not perfect and installing the weather station
on a roof can be difficult. Thus, you can calibrate for this error with a
wind speed multiplier.
In addition to the installation challenges, wind cup bearings (moving
parts) wear over time.
Without a calibrated source, wind speed can be difficult to measure.
We recommend using a calibrated wind meter (not included) and a
constant speed, high speed fan.
(7) The rain collector is calibrated at the factory based on the funnel
diameter. The bucket tips every 0.01” or 0.1m of rain (referred to as
resolution). The accumulated rainfall can be compared to a sight glass
rain gauge with an aperture of at least 4” or 0.1m.
Make sure you periodically clean the rain gauge funnel.
Page 66
66
Note: The purpose of calibration is to fine tune or correct for any sensor error
associated with the devices margin of error. Errors can occur due to electronic
variation (example, the temperature sensor is a resistive thermal device or
RTD, the humidity sensor is a capacitance device), mechanical variation, or
degradation (wearing of moving parts, contamination of sensors).
Calibration is only useful if you have a known calibrated source you can
compare it against, and is optional. This section discusses practices,
procedures and sources for sensor calibration to reduce manufacturing and
degradation errors. Do not compare your readings obtained from sources such
as the internet, radio, television or newspapers. The purpose of your weather
station is to measure conditions of your surroundings, which vary
significantly from location to location.
NOTE: UV Calibration MUST be performed every 2 to 3 months to
improve results. Over time, UV Index may alter results based on bright and
strong sunlight conditions. This is why diligent UV Calibration is
recommended.

6.2Weather Forecasting
The five weather icons are Sunny, Partly Cloudy, Cloudy, Rainy and

The forecast icon is based on the rate of change of barometric pressure.
Please allow at least one month for the weather station to learn the
barometric pressure over time.

6.3 Lightning Alert
The lightning icon will appear if the Dew Point exceeds 70 F. This
means there is a chance of lightning storms forming.
6.4 Weather Forecasting Description and Limitations
In general, if the rate of change of pressure increases, the weather is generally
improving (sunny to partly cloudy). If the rate of change of pressure decreases,
the weather is generally degrading (cloudy, rainy or stormy). If the rate of
change is relatively steady, it will read partly cloudy.
The reason the current conditions do not match the forecast icon is because
the forecast is a prediction 24-48 hours in advance. In most locations, this
prediction is only 70% accurate and it is a good idea to consult the National
Weather Service for more accurate weather forecasts. In some locations, this
prediction may be less or more accurate. However, it is still an interesting
educational tool for learning why the weather changes.
The National Weather Service (and other weather services such as
Accuweather and The Weather Channel) have many tools at their disposal to
predict weather conditions, including weather radar, weather models, and

7. Maintenance
The following steps should be taken for proper maintenance of your station
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 40: Rain gauge maintenance
2.Clean the solar radiation sensor and solar panel every 3 months with a
non-abrasive slightly damp cloth.
3.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 (while cleaning the solar panel).
4.When replacing the batteries, apply a corrosion preventing compound
on the battery terminals, available at Amazon and most hardware stores.
5. In snowy environments, spray the top of the weather station with
anti-icing silicon spray to prevent snow build up.

Problem
Solution
Wireless remote
(thermo-hygrometer) not
reporting in to console.
There are dashes on the
display console.
The maximum line of sight communication range
is about 150m. Move the sensor assembly closer
to the display console.
Resynchronize the remote sensor(s). Reference
Section 5.13.1&5.13.2.
Install a fresh set of batteries in the remote
sensor(s).
Make sure the remote sensors are not transmitting
through solid metal (acts as an RF shield), or earth
barrier (down a hill).
Radio Frequency (RF) Sensors cannot transmit
through metal barriers (example, aluminum
siding) or multiple, thick walls.
Move the display console around electrical noise
generating devices, such as computers, TVs and
other wireless transmitters or receivers.
Outdoor sensor array
does not communicate to
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 Installation.
With an open ended paperclip, press the reset
button for 3 seconds to completely discharge the
voltage.
Take out the batteries and wait one minute, while
covering the solar panel to drain the voltage.
10. Troubleshooting Guide
Look through the following table and locate an issue or problem you are
experiencing in the left column and read possible solutions in the right
column.
Page 76
76
Problem
Solution
Put batteries back in and resync with console by
powering down and up the console with the
sensor array about 10 feet away.
Bring the sensor array inside the house (you can
disconnect it from the rest of the sensors). 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 outside sensor array.
If the batteries were recently replaced, check the
polarity. If the sensor is flashing every 48
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.
Replace the batteries in the outside sensor array.
With the sensor array and console 10 feet away
from each other, remove AC power from the
display console and wait 10 seconds. Re-connect
power.
Temperature sensor
reads too high in the day
time.
Make certain that the sensor array is not too close
to heat generating sources or strictures, such as
buildings, pavement, walls or air conditioning
units.
Use the calibration feature to offset installation
issues related to radiant heat sources. Reference
6.6.

Problem
Solution
Absolute pressure does
not agree with official
reporting station
You may be viewing the relative pressure, not the
absolute pressure.
Select the absolute pressure. Make sure you
properly calibrate the sensor to an official local
weather station. Reference Section 6.6 for details.
Rain gauge reports rain
when it is not raining
An unstable mounting solution (sway in the
mounting pole) may result in the tipping bucket
incorrectly incrementing rainfall. Make sure you
have a stable, level mounting solution.
Data not reporting to
Wunderground.com
1. Confirm your password is correct. It is
the password you registered on
Wunderground.com. Your
Wunderground.com password cannot
begin with a non-alphanumeric character
(a limitation of Wundeground.com, not
the station). Example, $oewkrf is not a
valid password, but oewkrf$ is valid.
2. Confirm your station ID is correct. The
station ID is all caps, and the most
common issue is substituting an O for a 0
(or visa versa). Example,
KAZPHOEN11, not KAZPH0EN11
3. Make sure the date and time is correct on
the console. If incorrect, you may be
reporting old data, not real time data.
4. Make sure your time zone is set properly.
If incorrect, you may be reporting old
data, not real time data.
5. Check your router firewall settings. The
console sends data via Port 80.

ABSOLUTE AIR PRESSURE
ABSOLUTE BAROMETRIC
PRESSURE
Absolute air pressure is the air pressure
registered on a barometer without regard to
altitude.
BAROMETER
A barometer is a device that measures the
pressure of the air pushing on it—this
measurement is called the barometric
pressure. We don’t actually feel the
barometric pressure because the air pressure
is pushing equally in every direction.
BEAUFORT (Bft)
An indicator of wind force strength (not
speed) as it would act on a ship’s sails. Still
commonly in used in some locales to
indicate wind force.
DEW POINT
The temperature to which air must be cooled
to become saturated with water vapor. When
further cooled, the airborne water vapor will
condense to form liquid water (dew), or frost
if below freezing.
HEAT INDEX
The heat index (HI) or humiture is an index
that combines air temperature and relative
humidity, in shaded areas, as an attempt to
determine the human-perceived equivalent
temperature, as how hot it would feel if the
humidity were some other value in the shade.
HECTOPASCALS (hPa)
This is an international standard (SI system)
for measuring air pressure. It used to be
referred to as milli-bar (mb) and sometimes
still is. They are equivalent.
HYGROMETER
An instrument that measure relative
humidity of the air. This is expressed as a

INCHES OF MERCURY
(inHg)
This is the common unit of measurement for
air pressure in the United States. It refers to
the length of a standard column of mercury
(a liquid metal) that can be pushed up by the
ambient air pressure. Standard pressure is
approximately 29.92 inHg
KNOTS (kn)
One knot is equivalent to one nautical mile
and is sometimes used to indicate wind
speed.
LCD
An acronym for “Liquid Crystal Display.”
This is a common type of display screen used
in televisions, computers, watches, and digital
clocks.
LUX (lx)
The unit of illuminance (a measure of the
intensity of illumination on a surface) as used
in the SI system.
MILLIBAR (mb)
See HECTOPASCALS.
MM OF MERCURY (mmHg)
This is similar to inches of mercury, except
expressed in millimeters. Standard pressure is
approximately 760 mmHg.
NIST
National Institute of Standards and
Technology. A United States institute that
keeps very accurate time using atomic
clocks and provides and internet-based
service to accurately set device clocks.
RELATIVE AIR PRESSURE
RELATIVE BAROMETRIC
PRESSURE
Relative air pressure is the absolute air
pressure compensated for the altitude of the
barometer. The result is what the air pressure
would be at sea level.
TFT
Thin-Film-Transistor, a type of LCD screen.
ULTRA VIOLET INDEX
The ultraviolet index or UV-Index (UVI) is an
international standard measurement of the
strength of sunburn-producing ultraviolet

TERM
DESCRIPTION
(UV) radiation at a particular place and time.
The purpose of the UV Index is to help people
effectively protect themselves from UV
radiation. The UV Index is a linear scale, with
higher values representing a greater risk of
sunburn (which is correlated with other health
risks) due to UV exposure. An index of 0
corresponds to zero UV radiation, as is
essentially the case at night. An index of 10
corresponds roughly to midday summer
sunlight with a clear sky when the UV Index
was originally designed, but values above 10
are sometimes possible. Levels above 8 are
considered “very high” and above 11 are
considered “extreme.”
WIND CHILL
Wind chill (popularly wind chill factor) is the
lowering of body temperature due to the
passing-flow of lower-temperature air. In
other words, the air “feels” colder than it is
because of the chilling effect of the wind on
the skin.

The primary power source for the outdoor sensor is the solar panel. When
available solar power (light over recent period) is insufficient, the batteries
will be used. In outdoor climates that frequently have sustained temperatures
below 0°C (or 32°F) the use of Lithium batteries is strongly suggested as
these are performing better than Alkaline batteries under such circumstances.
