1.0 Set up Procedure

1. Pull away the water proof casing of
the transmitter to reveal the battery
compartment.

2. The attached cable of the wind
sensor will be in the corresponding
socket on the transmitter.

3. Remove the battery cover from the
monitor located on the back of the unit
and insert 2 x AA, 1.5V Alkaline batteries.

4. Remove the battery cover from the

Compartment

transmitter located below the socket and
insert 2 x AA, 1.5V Alkaline batteries and
close the cover.

Every time the transmitter is powered up (for example after a change of batteries),
the LED indicator will light up for 4 seconds (if no LED lights up or if the light stays
on permanently, make sure the battery is inserted correctly). After the transmitter is
powered up, the sensor will start to transmit regular outdoor temperature, relative
humidity and wind speed measurements.

NOTE: Each time the transmitter is powered up, a random security code will be
generated to distinguish itself from other transmitters around. If a battery change has
been made in the transmitter, the receiver must be reset so that the new security
code can be re-registered again.

2.0 Mounting
Before mounting the two units permanently ensure the units are working properly.

2.1 Monitor
Note diagram to the right for proper
flat surface setup.

The monitor can be mounted on a wall
or placed on any flat surface.

2.2 Transmitter
There are two mounting methods available for the transmitter.
To mount the transmitter to a pole, follow steps 1, 2, 3. To mount the transmitter to a
flat surface follow steps 1, 2, 4.

3.0 Indoor/Outdoor Temperature
The temperature measurement is displayed on the bottom left corner of the screen.
Press the IN/OUT TEMP button to switch between indoor and outdoor temperature.

4.0 Outdoor Relative Humidity
The humidity measurement is displayed on the bottom right corner of the screen.

5.0 Heat Index
Heat index is a combination of outdoor temperature and outdoor humidity into one
number to reflect perceived temperature. It is a measure of how the air “feels”.
As humidity increases, heat index goes up and the sensation of heat increases.

The monitor will display the heat index reading once it has been powered up.

IMPORTANT: Heat index is relevant when temperature is in the range of 26.6°C (80°F)
to 46.1°C (115°F), and outdoor humidity is 35% or above, outside of this range no
measurement is available or displayed.

When outdoor temperature and humidity are not in the effective calculating range
of heat index, then current outdoor temperature will be displayed instead (the words
Heat Index and Humidex will not be displayed on the screen when Heat Index is out
of range).

6.0 Humidex
Press the Heat Index/Humidex button to show Humidex readings on the monitor.
Humidex is the same indication of how the air “feels” with the same principles of heat
index, however, it uses the Canadian standard calculation which is generally a higher
value than the Heat Index.

IMPORTANT: Humidex is relevant when temperature is in the range of 21°C (69.8°F)
to 43°C (109.4°F) and outdoor humidity is 20% or above, outside of this range no
measurement is available or displayed.

When outdoor temperature and humidity are not in the effective calculating range of
humidex, then current outdoor temperature will be displayed instead (the words Heat
Index and Humidex will not be displayed on the screen when Humidex is out of range).

7.0 Heat Stress Index Scale
The Heat Stress Index is a valuable measure of the effect of humidity on how “hot it
feels”. Since our bodies primary cooling mechanism is through perspiration and the
cooling effect of evaporation from our skin; as the humidity increases, there is less
evaporation and we feel hotter.
At a certain point, high Heat Index/Humidex values become a health issue and a
serious one for people who are working or exercising in it. The color LCD scale reflects
the Heat Stress Index values and relates to the health affects outlined below:

Condition Heat Index /

Physical Response

Humidex Value

Caution 27°C to 31°C

80°F to 89°F

Extreme Caution 32°C to 40°C

90°F to 104°F

• Fatigue possible with prolonged
exposure and physical activity

• Sunstroke, muscle cramps and heat
exhaustion are possible with
prolonged exposure and physical
activity

Danger 41°C to 53°C

105°F to 129°F

• Sunstroke, muscle cramps and heat
exhaustion are likely

• Heat stroke possible with prolonged
exposure and physical activity

Extreme Danger 54°C/130°F

• Heat stroke and sunstroke likely

or higher

8.0 Wind Chill
Press the Wind Speed/Wind Chill button to switch from wind speed to wind chill on
the monitor.
