Display Console Set Up
It is recommended to plug in the power supply to reduce the battery consumption and extend the
service life.
Note: The sensor array must be powered and updating before powering up the console, or the
console will time-out searching for the sensors. Power up the console last.
Make certain the weather station sensor array is at least 3m away from the console and within 30m of the
console. If the weather station is too close or too far away, it may not receive a proper signal. If you have more
than one thermo-hygrometer transmitter, make sure they are all powered up and transmitting on different
channels.
Remove the battery door on the back of the display, as shown in Figure 11. Insert three AAA (alkaline or
lithium)) batteries in the back of the display console. The display will beep once, and all of the LCD segments
will light up for a few seconds to verify all segments are operating properly.
Note: The character contrast is best from a slightly elevated viewing angle.
Figure 11
Replace the battery door, fold out the desk stand and place the console in the upright position.
The unit will instantly display indoor temperature, humidity, pressure, tendency, moon phase, and time. The
wind speed, wind gust, wind direction, rain, UV/sunlight, thermo-hygrometer sensors, integrated outdoor
temperature and humidity will update on the display within a few minutes.
Do not press any menu buttons until the data from the outside transmitter is displayed, otherwise the outdoor
sensor search mode will be terminated. When the outdoor transmitter data has been received, the console will
automatically switch to normal mode, from which all further settings can be performed.
While in the search mode, the remote search icon will be constantly displayed.
If you have more than one thermo-hygrometer sensor (up to eight thermo-hygrometer sensors are supported),
the display will automatically toggle between sensors until all sensors have reported in.
If it does not update, please reference the troubleshooting guide in Section 12.

15
Note: The power adaptor is intended to be correctly oriented in a vertical or floor mounted position. The
prongs are not designed to hold the plug in place if it is plugged into a ceiling, under-table or cabinet outlet.
Figure 12
Note: If the power adaptor is plugged in, BL ON will display in the time area for three seconds when
powered up. Conversely, if the power adaptor is not plugged in, AC OFF will be displayed, the icon will
display.
Sensor Operation Verification
The following steps verify proper operation of the sensors prior to installing the sensor array.
1. Verify proper operation of the rain gauge. Tip the sensor array back and forth several times. You should
hear a “clicking” sound within the rain gauge. Verify the rain reading on the display console is not reading
0.00. Each “click” represents 0.3mm of rainfall.
2. Verify proper operation of the wind speed sensor. Rotate the wind cups manually or with a constant
speed fan. Verify the wind speed is not reading 0.0.
3. Verify proper operation of the indoor and outdoor temperature sensors. Verify the indoor and outdoor
temperature readings match closely with the console and sensor array in the same location (about 3m apart).
The sensors should be within 2°C (the accuracy is ±1°C). Allow about 30 minutes for both sensors to stabilise.
4. Verify proper operation of the indoor and outdoor humidity sensors. Verify the indoor and outdoor
humidity readings match closely with the console and sensor array in the same location (about 3m apart). The
sensors should be within 10% (the accuracy is ± 5%). Allow about 30 minutes for both sensors to stabilise.

4. Weather Station Installation
4.1 Pre-Installation
Before installing your weather station in its 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 familiarise 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 will need to clean the rain gauge once per year and change the batteries every two 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 15cm
from any building, structure, ground, or roof top.
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 6m tall, install it 4 x 6m = 24m
away. Use common sense: if the weather station is installed next to a tall building, the wind and rain will not be
accurate.
4. Wireless Range. The radio communication between receiver and transmitter in an open field can reach a
distance of up to 100m, providing there are no interfering obstacles such as buildings, trees, vehicles, or high
voltage lines. Wireless signals will not penetrate metal buildings. Most applications will only reach 30m due to
building obstructions, walls and interference.
5. Radio interference from devices 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.
4.3 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the
following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and
TVs.
2. 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.
3. Line of Sight Rating. This device is rated at 100m line of sight (no interference, barriers or walls) but
typically you will get 30m maximum under most real-world installations, which include passing through barriers
or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminium siding. If you have
metal siding, align the remote and 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

5-15%
Plastics
10-15%

4.4 Installation of Integrated Outdoor Transmitter
The DWS7100 can be used in both the Northern and Southern Hemispheres.
Prior to installation, you will need to calibrate the wind direction as shown below.
Northern Hemispheres (NOR)
The cardinal directions (N, S, E, W) moulded on the body of the outdoor sensor are indicators for the Northern
Hemisphere only.
Step 1: There is an “S” indicator on the wind vane that indicates South, as shown in Figure 13. Align this “S”
marker in the direction of South.
Step 2: Console operation is set to Northern Hemispheres (NOR in the time area) in Location division.
Note: There are four letters of “N”, ”E”, ”S” and “W” around the wind direction, representing for the
direction of North, East, South and West. The 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 if the
wind direction sensor is not positioned correctly during installation.

18
Northern Hemispheres
Southern Hemispheres
Figure 13
Southern Hemispheres (SOU)
For Southern Hemisphere installations, ignore these (N, S, E, W) and face the solar panel to the North (and
in a sunny position) when it comes to installing the Integrated outdoor transmitter.
Step 1: Install the Integrated outdoor transmitter and face the solar panel North.
Step 2: Set the Console operation to Southern Hemispheres (SOU in the time area) in Location division.
Note: Permanent wind direction error of approximately 180º will occur if the wind direction sensor is not
positioned correctly during installation.
