B. Thermometer-Transmitter Sensor
The data from the outdoor sensor is transmitted every 128 seconds
to bring you the latest weather information which is displayed
on the television screen or PC (updating information faster is
prohibited by FCC criteria and would drastically reduce battery
life). The thermometer-transmitter sensor connects to the wind
and rain sensors via insulated cables, whereby power and weather
information is transferred. The collected data is then transmitted by
the thermometer-transmitter back to the indoor receiver wirelessly.
Weather data is sent from the thermometer-transmitter sensor by
Thermometerradio signal at 433MHz (up to 60 yards / 60 meters, approximately 200
Transmitter
feet, in open space). The thermometer-transmitter sensor consists of
Sensor
the main unit, rain protection cover and base bracket.
Wind
Sensor
Power Adaptor: a special transmitter adaptor is available to supply power
to the transmitter rather than using batteries. It is a perfect solution for
your HWS during extremely cold temperatures in the winter months when
batteries may cause problems. Please call 1-866-753-0181 for ordering
information if not found at your local retailer.
Rain Sensor
C. Wind Sensor
The wind sensor measures wind speed and wind direction and sends the data to the thermometer-transmitter
sensor, which in turn transmits the data to the indoor receiver. Operating power is taken from the thermometertransmitter sensor by cable connection. The wind sensor consists of the main unit with wind vane, 30 ft./9 m wired
phone cord (already attached to the main unit), mast, and base bracket.
D. Rain Sensor
The self-emptying rain sensor measures cumulative rainfall and sends the data to the thermometer-transmitter
sensor which in turn transmits the data to the indoor receiver. Operating power is taken from the thermometertransmitter sensor by cable connection. The rain sensor consists of the main unit and 30 ft./9 m wired phone cord
(already attached to the main unit).
4. MOUNTING
CAUTION: Great care must be taken when mounting the Home Weather Station for Television or PC components.
The manufacturer/supplier can not be held liable for personal or property damage when setting up the components.
Please use caution when choosing a mounting point.
Prior to drilling mounting holes and permanently affixing any of the units, please ensure the following points are
considered:
1. Cable lengths of the units meet with your distance requirements at mounting points.
2. Signal from the thermometer-transmitter sensor can be received by the indoor receiver at mounting point.
3. Make sure the transmitter is easily accessible. You will have to periodically replace batteries. Mount it as close to
the ground as possible.
A. Indoor Receiver
For accurate data transmission:
• Make sure that the indoor receiver is not placed in direct sunlight or placed in an area with drafts caused by heaters
or air conditioners
• Do not mount the indoor receiver on a wall
• Do not place the indoor receiver on or near any appliances that emit heat, i.e. televisions, VCR's, DVD players,
amplifiers, etc. Doing so may result in inaccurate temperature and humidity readings.
• The receiver has air vents to help ensure accurate temperature. Make sure that water does not enter the unit.
B. Wind Sensor
NOTE: Make sure the following contents have been included with your
HWS for mounting the wind sensor:
• 2 x U-bolts to secure to a mast
• 8 x washers
• 4 x nuts
• 8 x 0.25” screws (to fix mast to main unit and base bracket)
• 4 x 2.75” screws (to fix base bracket to a flat surface)
First, choose whether the wind sensor will be mounted vertically or
horizontally (on a mast). Make sure that you position the wind sensor
in a free, open area that is not protected by objects, which may distort
or interfere with the wind (e.g. large buildings, trees, chimney, etc.).
Cable Preparation for Vertical Mounting
1. Run the cable that is already fastened to the wind sensor through
the vertical joining section (see right).
2. Run the cable through the extension pole but do not secure the
pole to any sections yet.
3. Now run the cable through the top of the base-bracket and the
through the small rectangular section found on one side of the
base-bracket.
NOTE: Make sure that you completely pull the cable through the wind
sensors extension pole and base-bracket to reduce the amount of
slack on the cord.
Vertical Mount
1. Make sure that the wind vane can rotate freely before fastening the
unit permanently into position.
2. Insert one end of the extension pole provided into the base-bracket.
3. Secure the connection point of the extension pole and base-bracket
using the 0.25” metal screws provided to prevent rotation at the
joining point. (Use 4 x 0.25” screws to ensure stability).
4. Insert the vertical joining section on the bottom of the wind sensor
into the top of the extension pole. (Ensure that you pull all cable
slack through the side of the base-bracket to prevent creasing or
cutting the cable).
5. Secure the wind sensor to the extension pole using the 0.25” screws
provided to make sure that the pole connection does not rotate.
(Use 4 x 0.25” screws to ensure stability).
IMPORTANT: For accurate readings, it is important to mount the
wind sensor so that the “N” (north) on the casing is facing the correct
direction (north). If necessary, use a standard compass to determine
north.
6. Using
4 x 2.75”screws provided, secure the wind sensors basebracket to a flat surface.
NOTE: Make sure that when you are securing the base
bracket with the 2.75“ screws, you are aware of the
cable. Prevent driving a screw through the cable.
VERTICAL
MOUNT
NOTE: For proper wind speed measurement ensure the
vertical joining section is at 90° to the horizon (Fig. A)
Fig. A
Horizontal Mounting
Cable Preparation for Horizontal Mounting
1. Run the cable that is already fastened to the wind sensor through the horizontal joining section (see below).
2. Run the cable through the extension pole but do not secure the pole to any sections yet.
3. Now run the cable through the top of the base-bracket and then through the small rectangular section found on
one side of the base-bracket.
NOTE: Make sure that you completely pull the cable through the wind sensor's extension pole and base-bracket to
reduce the amount of slack on the cord.
Horizontal mount – using a mast/antenna/pole
NOTE: It is not recommended to secure the wind sensor horizontally from a wall or chimney because doing so will
interrupt the flow of wind from at least one direction.
1. Make sure that the wind vane can rotate freely before fastening the unit permanently.
2. Using 2 x U-bolts, 4 x nuts and 4 x washers, secure the base-bracket of the wind sensor
to a stable mast/antenna/pole. (Masts made of magnetic materials, such as lead or
other dense metals will cause faulty readings).
IMPORTANT: Make sure that the pole insert of the base-bracket is facing north (N) and
the pilot holes are on the top AND bottom.
3. Use the pole extension provided to distance the wind sensor from the stable mast/antenna/pole. Insert one end of
the pole extension into the base-bracket.
4. Secure the connection point of the pole extension and base-bracket using the 0.25” screws provided to prevent
rotation at joining point. (Use 4 x 0.25” screws to ensure stability).
5. Insert the pole extension into the horizontal joining section. (Ensure that you pull all cable slack through the side of
the base-bracket to prevent creasing or cutting the cable).
IMPORTANT: For accurate readings, it is important to mount the wind sensor so that the “N” (north) on the casing is
facing the correct direction (north). If necessary, use a standard compass to determine north.
6. Secure the horizontal joining section to the mounting pole using the 0.25” screws provided to make sure that the
pole connection does not rotate.
HORIZONTAL MOUNT
C. Self-Emptying Rain Sensor
NOTE: make sure the following contents have been included with your HWS for mounting the rain sensor:
• 2 x 2.75” screws (to fix rain sensor to a flat surface)
Place the rain sensor as far away as possible from tall buildings, trees or other obstructions. It is suggested that the
rain sensor should be no closer to tall objects or obstructions than twice the height of the object compared to the
sensor. However, low bushes, fences or walls in the vicinity of the rain sensor are not objectionable, as these usually
help break up the force of the wind during stormy weather conditions.
NOTE: It is recommended that you mount the rain sensor 18“ (46 cm) above ground or surface to prevent water from
splashing off the ground/surface, into your rain sensor.
1. In order for the rain sensor to work properly, you MUST place the rain sensor on a level, horizontal surface.
Use of a bubble level (not included) will ensure a proper mounting.
2. Remove the rain sensor lid by pushing on the tabs on the front and back, and pulling it upwards off the base.
3. Test that water can flow freely between the base of the rain sensor and horizontal mounting surface – pour clear
water over the water collection device and view the flow.
4. Using 2 x 2.75” screws, secure the base of the rain gauge to the flat, horizontal surface.
D. Thermometer-Transmitter Sensor
NOTE: make sure the following contents have been included with your HWS for mounting the thermometertransmitter sensor:
• 2 x 1.75” wall mounting screws
• requires 4 x “AA” batteries
• plastic anchors for screws
It is recommended that you mount the transmitter in a shaded area out of direct sunlight. Placing the transmitter in
direct sunlight will affect the outdoor temperature considerably.
It is recommended to mount the unit approximately 6 ft/2 m above the ground on the north side of a structure,
preferably in a shaded area.

8. CHANGING THE BATTERIES IN THE TRANSMITTER
1. Press and hold the RAINFALL and WIND SPEED/GUST button at the same time until the red LED light starts to flash
quickly.
2. Follow steps 6-9 in the "Powering up your HWS for Television" section above.
9. WIRELESS TRANSMISSION
The HWS utilizes a transmitter, which broadcasts at 433MHz approximately every 128 seconds. Like a cell phone
signal, the transmission strength is affected by many external objects that cause electromagnetic interference.
Proximity to power and electrical appliances adversely affect the signal. Therefore, we strongly advise that you
experiment with the placement of both the transmitter and the indoor receiver. If the conditions are good, you will
be able to transmit at the maximum range of 60 yards / 60 meters but if you are in an area with a lot of
interference, the range will be less.
10. WIRED TRANSMISSION
You may also link your indoor receiver directly to the transmitter using wired cord, rather than using
batteries. This is a perfect solution for your home weather station during the cold months when the life of
batteries is drastically reduced or non-existent.
To purchase wired phone cord, you can go to your local phone and electronics store.
NOTE: It is important to only use 4 conductor phone cord.
To power up your HWS using wired phone cord, follow the “Powering up your HWS for Television” steps, except don't
insert any batteries into the transmitter, instead insert one end of the wired phone cord into the indoor receiver and
the other end into the transmitter. Do the same when powering up your HWS for PC.

After about 40 seconds, the reading will return to 0.0 inch (or 0.0 cm).
11
15. RAIN GAUGE MAINTENANCE
• It is recommended that you inspect and clean your rain gauge every couple of months. Remove any
leaves that may have fallen into the collection bowl, especially after a particularly windy period.
• Remove the lid on the rain gauge and check if there is anything obstructing the tipping bucket
mechanism.
• The rain gauge is not designed to register snowfall, therefore, to avoid damage to the unit, it is
recommended that you bring the unit in during the winter, or if it is mounted in a permanent position,
cover it to protect it from snowfall.
16. TREND CHART
Please review the following tips on understanding your trend chart.
NOTE:
• The trend chart will not appear on the television screen or PC after powering up the indoor receiver for
the first time. It has to collect air pressure data for 24 hours before it can display a trend.
• If at anytime power is lost to the indoor receiver, all trend information will be erased and must be
collected again for 24 hours to display a trend once the power is restored.
12
17. WEATHER FORECASTING
• Weather forecasting is an extremely complex science. Even professional meteorologists with the best
equipment and the aid of radar and satellite imagery often have difficulty forecasting with absolute
certainty. The prediction models meteorologists use consider many weather variables; including:
barometric pressure, wind direction, wind speed, dew point, etc.
• The forecast function in the Home Weather Station is based solely on barometric pressure and the trend
recordings of general weather conditions associated with various pressure levels. It therefore has a
limited ability to forecast for the multitude of specific conditions it will encounter. It provides a general
forecast of weather changes in the same way a wall barometer forecasts changes in weather, however it
does record and account for trends that influences the forecast icon.
IMPORTANT:
• The forecast icon will always appear as “Partly Cloudy” upon powering up the indoor receiver. During this
time the main station is collecting pressure information in order to generate a proper forecast.
• The first 72 hours of forecast icons may be inaccurate from what you are viewing out your window,
however, the unit continually gathers pressure data to develop trends, in turn predicting forecasts of
coming weather conditions. The longer the station is powered increases the forecast accuracy.
18. WIND CHILL
• Wind chill is a combination of both the outdoor temperature and wind speed.
• For the wind chill to display on the television screen the outdoor temperature needs to be above -58ºF
(–50ºC ) and below 50 ºF (10 ºC) and the wind speed needs to be above 3 mph (4.8 km/hr) and below 110
mph (177 km/hr). If the outdoor temperature and wind speed are out of range, the wind chill will display
dashes (“---“).
19. BAROMETRIC PRESSURE
• The Home Weather Station’s barometer display will differ from local sources (TV, radio, internet, etc.). This
is because barometric pressure quoted in these types of mediums is “barometric pressure adjusted to sea
level”, which is theoretical atmospheric pressure that accounts for decreasing air pressure with elevation.
Air pressure decreases 1.0 inHg for every 1000 feet you go up in elevation. Consequently, the air pressure
at the top of a mountain is considerably less than at sea level.
• The HWS uses a sensor to measure the “absolute” or actual barometric pressure. For forecasting purposes,
however, the relative changes in pressure and pressure trends indicate the coming weather. In general,
rising pressure indicates improving weather, while falling pressure indicates deterioration of current
conditions.
• To determine theoretical atmospheric pressure, please follow this procedure:
13
NOTE: If using the PC please refer to the Weather Analyzer Software instruction manual enclosed with this
unit (Section 6B: Basic Settings and Alarm Settings - Altitude).
1. Determine your elevation (meters or feet above sea level) by using TABLE 1 or 2 below. The internet
or an atlas are also good sources to determine your elevation if the chart does not provide the correct
information for your general area (View section: Resources to look at).
2. Using the barometric tables (TABLE 3 - TABLE 11), find the table that is close to your current elevation:
TABLE 3 = 250 m above sea level
TABLE 8 = 1500 m above sea level
TABLE 4 = 500 m above sea level
TABLE 9 = 1750 m above sea level
TABLE 5 = 750 m above sea level
TABLE 10 = 2000 m above sea level
TABLE 6 = 1000 m above sea level
TABLE 11 = 2250 m above sea level
TABLE 7 = 1250 m above sea level
3. Once you have chosen the correct table, view the pressure reading on the television screen and run your
finger along the top of the table until the current pressure falls between the correct range.
4. Now view the outdoor temperature reading on the television screen and run your finger down the
pressure column to match the temperature range along the left side of the table.
5. Your finger now lays on the number of millibars (mb) you must add to the absolute pressure on the
television screen to determine theoretical atmospheric pressure.
NOTE: You must repeat the actions above every time there is a change in pressure, temperature or altitude
to retrieve the correct theoretical atmospheric pressure.
Example:
AUSTIN, TX
Elevation (TABLE 1): 505 ft above sea level
HWS current barometric pressure reading: 29.16 inHg
HWS current outdoor temperature reading: 77°F
a) Go to TABLE 3 (820 ft above sea level), which is the closest table to Austin's elevation.
b) Run finger along the top of table to reach 28.64-29.23 inHg.
c) Run finger down chart to reach 60.8 to 78.7 ºF.
d) Add 0.85 inHg to the current pressure reading on HWS: 0.85 inHg + 29.16 inHg = 30.01 inHg
Theoretical Atmospheric Pressure = 30.01 inHg

21. TROUBLESHOOTING
Screen does not appear on
television or PC
A. This occurs because there is no power supplied to the main unit.
1. Check the AC power connections to the receiving unit and the power from
the wall outlet.
2. Check the batteries and replace if needed. (View section 8: Changing
Batteries in the Transmitter)
3. Check the polarity of the batteries in the battery compartment.
4. Check to make sure your television is on the correct video/input.
Outdoor information not
displayed, “---”
A. This is usually caused by transmission interference or low battery power in
the transmitter.
Items in the home that
generate frequency trouble:
• Family radios
(CB’s, walkie-talkie)
• Digital cable or satellite boxes
radiate frequencies that will
interfere with transmission
• HAM radios
• Microwave ovens
• High voltage wiring
B. Did you perform the SET ID operation with the outdoor sensors plugged into
the thermometer-transmitter?
i) Are there dashes for the outdoor temperature reading?
ii) Are there dashes for the wind speed reading?
iii) Are there dashes for the wind direction reading?
IF YES TO ALL QUESTIONS ABOVE:
1. Check batteries in the transmitter. Replace if needed. (View section 7:
Changing Batteries in the Transmitter)
2. Bring the indoor receiver beside the transmitter and remove all the batteries
and AC adaptor. Replace them all (View section 6: Powering up Your HWS)
and observe whether ALL the outdoor readings show up. Check the timing
of updates on the television screen or PC (outdoor readings should change
every 128 seconds). Then, place the indoor receiver back in the regular
position. Check the timing of updates AGAIN on the television screen or
PC. If you notice the updates occur every 40 seconds, there should be no
problem.
If the screen has not updated within 5 minutes or no updates occur there is
transmission interference between the indoor receiver and the transmitter.
BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE
TRANSMISSION INTERFERENCE.
IF THERE ARE DASHES ONLY WHERE THE WIND SPEED AND DIRECTION ARE
DISPLAYED AND THE UNIT IS REGISTERING AN OUTDOOR TEMPERATURE:
3. Check that the wires are connected from the wind sensor to the transmitter
in the right slot (labeled "wind") and are fully inserted. If the wind sensor
was not inserted properly, remove the batteries / AC adaptor from both
components and re-insert them. (View section 6 or 7: Powering up Your
HWS)
20
Outdoor readings stopped after
two days, one week, etc
1. Battery voltage supplied by the 4 x “AA” batteries in the transmitter
is affected by cold weather, especially alkaline batteries. Low voltage
decreases the transmission distance significantly. If you are experiencing
weather below 14 ºF/-10 °C, it is suggested to use lithium batteries and
place the indoor receiver and transmitter as close as possible to each other.
Power Adaptor: a special transmitter adaptor is available to supply power
to the transmitter rather than using batteries. It is a perfect solution for
your HWS during extremely cold temperatures in the winter months when
batteries may cause problems. Please call 1-866-753-0181 for ordering
information.
Wired Transmission: you may also link your indoor receiver directly to the
transmitter using wired phone cord (View section 10: Wired Transmission)
1. Electrical storms can cause transmission to stop. If this occurs, you must
reset the indoor receiver and transmitter by removing the batteries / AC
adaptor and resetting the HWS (View section 6 or 7: Powering up your HWS).
DO NOT do this during the electrical storm!
2. Electromagnetic interference can occur from different sources that transmit
radio waves that may affect how the indoor receiver receives data from
the transmitter (if at all). It is recommended that you place the transmitter
and indoor receiver significantly close together if there is a large amount
of electromagnetic interference in your area. Even interference from
appliances in your home may cause transmission to stop.
3. Bring the indoor receiver beside the transmitter and remove all the batteries
and AC adaptor. Replace them all (View section 6 or 7: Powering up Your
HWS) and observe whether ALL the outdoor readings show up. Check
the timing of updates on the television screen or PC (outdoor readings
should change every 128 seconds). Then, place the indoor receiver back in
the regular position. Check the timing of updates AGAIN on the television
screen or PC. If you notice the updates occur every 128 seconds, there
should be no problem.
If the screen has not updated within 5 minutes or no updates occur there is
transmission interference between the indoor receiver and the transmitter.
BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE
TRANSMISSION INTERFERENCE.
Wind direction is displaying
faulty readings
i) Are you mounting the unit on a mast or metal pole?
ii) Do you know what the pole is made of?
Wind direction is stuck on one
direction
1. Aluminum poles should not affect the wind direction readings, however,
masts or poles made of lead or other dense metals can affect the magnetic
sensors in the wind sensor causing the unusual readings. Move the wind
sensor, if necessary, or use the vertical mount procedure. (View section 4B:
Mounting)
21
2. Freezing rain can cause the wind direction pointer to stop moving, thus
constantly displaying the same direction. You can attempt to remove
the ice from the wind sensor, but it is strongly advised to wait for milder
weather to do so.
3. This is also an indication that there is transmission interference or batteries
have died in the transmitter. Check the batteries in the transmitter. Replace
if needed. (View section 8: Changing Batteries in the Transmitter).
4. Make sure that the wind speed sensor is securely fastened in the “wind” slot
on the transmitter. (View section 5: Connecting the Sensors)
5. Bring the indoor receiver beside the transmitter and remove all the batteries
and AC adaptor. Replace them all (View section 6 or 7: Powering up Your
HWS) and observe whether ALL the outdoor readings show up. Check
the timing of updates on the television screen or PC (outdoor readings
should change every 128 seconds). Then, place the indoor receiver back in
the regular position. Check the timing of updates AGAIN on the television
screen or PC. If you notice the updates occur every 128 seconds, there
should be no problem.
If the screen has not updated within 5 minutes or no updates occur there is
transmission interference between the indoor receiver and the transmitter.
BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE
TRANSMISSION INTERFERENCE.
Only transmits when the
transmitter is right beside the
indoor receiver
A. There is a large amount of transmission interference with the current
location of the indoor receiver and transmitter. There may be too many
walls or electrical interference (caused by appliances in your home)
between the two units.
1. Significantly reduce the distance between the indoor receiver and the
transmitter.
2. Bring the indoor receiver beside the transmitter and remove all the batteries
and AC adaptor. Replace them all (View section 6 or 7: Powering up Your
HWS) and observe whether ALL the outdoor readings show up. Check
the timing of updates on the television screen or PC (outdoor readings
should change every 128 seconds). Then, place the indoor receiver back in
the regular position. Check the timing of updates AGAIN on the television
screen or PC. If you notice the updates occur every 128 seconds, there
should be no problem.
If the screen has not updated within 5 minutes or no updates occur there is
transmission interference between the indoor receiver and the transmitter.
BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE
TRANSMISSION INTERFERENCE.

No outdoor readings occur even
after resetting the units
A. Make sure that you have unplugged and removed the batteries / AC
adaptor from the main unit AND the transmitter. Re-insert the batteries
in the transmitter ONLY. Put the transmitter directly on top of a radio
(preferably a clock-radio due to the size – stereo radios may be too large
for this test), and tune the radio to FM 107.9. You should hear a loud beep
or pulse roughly every 128 seconds. Time the pulse to ensure this occurs
approximately every 128 seconds. If no pulse is heard, the transmitter’s
batteries are dead or the transmitter is defective.
If the pulse does occur approximately every 10 seconds, place the main unit
and the transmitter side by side (turn off your radio). Remove all the batteries
and AC adaptor. Replace them all (View section 6 or 7: Powering up Your HWS)
and observe whether ALL the outdoor readings show up. Check the timing of
updates on the television screen or PC (outdoor readings should change every
128 seconds). Then, place the indoor receiver back in the regular position.
Check the timing of updates AGAIN on the television screen or PC. If you
notice the updates occur every 128 seconds, there should be no problem.
If the screen has not updated within 5 minutes or no updates occur there is
transmission interference between the indoor receiver and the transmitter.
BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE
TRANSMISSION INTERFERENCE.
** NOTE: the radio test is only confirming that the transmitter is sending out a
signal. This proves that the transmitter should not be sent back because it is
diagnosed as faulty**
Wind speed too high
(117 mph to 124 mph /
190 km to 200 km)
Transmission issues usually cause this to occur from other appliances or
radio waves in the air. If the problem persists, you should consider replacing
the batteries in the transmitter (View section 8: Changing Batteries in the
Transmitter) and possibly moving the location of the transmitter and indoor
receiver.
Wind speed too low
1. This situation can occur because the wind speed transmission is NOT REAL
TIME. The wind speed is an average reading of gusts collected before
transmission, therefore if wind gusts happen (every 128 seconds) to dip
below the perceived wind speed over the measuring period, the average
will be reduced, resulting in what appears to be a low reading.
Wind speed not accurate
Wind speed does not change
2. Is the wind sensor clear of obstructions?
Wind speed & direction can be affected radically by obstructions that
interfere with actual wind. This affect can take place many meters away
from the sensor.
Example: a 40’ tree even 50 yards from the sensor on the roof of a house
will disturb enough wind that the unit will never give proper data from the
direction of that tree.
23
3. Wind speed and directional data will not change if there is “transmission
interference”. That means that some of the data transmitted has been
corrupted by other sources emitting waves. This could be anything – wiring
in walls, appliances, other electrical devices operating in proximity of the
indoor receiver or transmitter, or between the two.
4. Freezing rain can cause the wind speed cups to stop moving, thus constantly
displaying 0.0 wind speed. You can attempt to remove the ice from the wind
sensor, but it is strongly advised to wait for milder weather to do so.
5. Make sure the wind speed sensor cord is securely fastened in the “wind” slot
on the transmitter. (View section 5: Connecting the Sensors) and that the
sensor is level with the horizon.
Bring the indoor receiver beside the transmitter and remove all the batteries
and AC adaptor. Replace them all (View section 6 or 7: Powering up Your
HWS) and observe whether ALL the outdoor readings show up. Check the
timing of updates on the television screen or PC (outdoor readings should
change every 128 seconds). Then, place the indoor receiver in the regular
position. Check the timing of updates AGAIN on the television screen or
PC. If you notice the updates occur every 128 seconds, there should be no
problem.
If the screen has not updated within 5 minutes or no updates occur there is
transmission interference between the indoor receiver and the transmitter.
BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE
TRANSMISSION INTERFERENCE.
Barometric trend doesn’t work
The trend function will not display after power up until it has collected 24
hours of pressure data. (View section 16: Trend Chart).
Forecast icons don’t change
The forecast icon will always appear as “Partly Cloudy” upon powering up the
indoor receiver. The first several hours of forecast data may be inaccurate,
because the indoor receiver needs to collect barometric pressure information.
Over time the forecast icon’s accuracy will improve. (View section 17: Weather
Forecasting)
Battery consumption
The Home Weather station requires constant battery power to accurately
scan outdoor weather readings. The wind speed sensor and the 60 yards (200
ft. approximately) transmission is the main cause of power consumption. In
normal temperature ranges (50 °F to 80 °F/10 °C to 25 °C), you can expect that
the 4 x "AA" batteries in the transmitter will last approximately 7 weeks (even
lithium batteries).
In colder temperatures, battery life is much less – note that the use of lithium
batteries allow the chemical reaction that is creating power to occur in colder
temperatures (-40 °F / -40 °C) compared to alkaline batteries, which fail at
approximately 14 °F (-10°C), but it does not necessarily mean that the battery’s
charge will last longer.
Consider the amount of times you must recharge your cell phone or digital
camera. All of these items, including the HWS, use a lot of power to perform
perfectly. For power saving consider:
24
Power Adaptor: a special transmitter adaptor is available to supply power to
the transmitter rather than using batteries. It is a perfect solution for your HWS
during extremely cold temperatures in the winter months when batteries may
cause problems. Please call 1-866-753-0181 for ordering information.
Wired Transmission: you may also link your indoor receiver directly to the
transmitter using wired phone cord. (View section 10: Wired Transmission)
