QUICK SET UP MANUAL –

PROFESSIONAL WEATHER CENTRE

INITIAL SETUP:

Note: When putting the Weather Centre into operation,

it is important to have them in close proximity (e.g. on a

table) while completing wiring and set-up of the system.

This step is important to allow testing of all components

for correct function before placing and mounting them at

their final destinations (See Positioning below).

1. Unwind the cables of the Wind sensor. Connect

the Wind sensor to the Thermo-hygro transmitter

by plugging the connector head into the socket of

the Thermo-hygro sensor.

2. First insert the batteries into the Thermo-hygro sensor and optional rain sensor

(purchased separately) (See How to install and replace the batteries into the

Thermo-hygro sensor and How to install and replace the batteries into the rain

sensor below).

3. Then insert the batteries into the Weather Centre (See How to install and replace

the batteries into the Weather Centre below). Once the batteries are installed, all

segments of the LCD will light up. It will then display the time as 12:00, the date as

1.1.09, the weather icons, and air pressure value. "- - -" will be shown for outdoor

data.

4. The Weather Centre will start receiving data from the transmitter. The transmission

reception icon will be blinking to indicate that the centre is trying to get the thermo-

hygro transmitter data. The outdoor temperature, humidity and wind data should

then be displayed on the Weather Centre. If this does not happen after 135 seconds,

the batteries will need to be removed from all units. You will have to start again from

step 2.

5. The transmitter reception icon is now blinking again to indicate that the centre is

trying to get the rain sensor data. It will stop blinking once the rain sensor has been

detected. If this does not happen after 135 seconds, you will need to start again from

step 2.

6. You may need to check the cable for correct connection and all the components for

correct function by manually turning the wind-gauge by moving the wind-vane; tilting

the rain sensor to hear the impact of the internal moving seesaw, etc. (see

Positioning below).

7. Time and date must be manually set.

8. After the Weather Centre has been checked for correct function with regard to the

above points and found fit, the initial set up of the weather centre system is finished

and the mounting of the system components can take place. It must be ensured

Socket for wind

sensor

however that all components work properly together at their chosen mounting or

standing locations.

Note: After batteries are installed in the transmitter, install the batteries in the weather

centre to receive the signal from the transmitters as soon as possible. If the weather

centre is powered more than 5 hours after the transmitter is powered, the weather centre

will never receive the signal successfully from the transmitters. In this case, you will need

to reinstall the batteries for all the transmitters to redo the setup procedure.

After the batteries are installed, there will be synchronization between weather centre and

the transmitters. At this time, the signal reception icon will be blinking. When the signal

is successfully received by the Weather Centre, the icon will be switched on. (If it is not

successful, the icon will not be shown in LCD) This allows you to see whether the last

reception was successful (icon on) or not (icon off). Short blinking of the icon shows that a

reception is in progress.

If the signal reception is not successful on the first frequency (921MHz) for 45 seconds,

the frequency is changed to 926MHz and the learning is tried another 45 seconds. If still

not successful, the reception is tried for 45 seconds on 916MHz. This will also be done for

re-synchronization.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMO-

HYGRO TRANSMITTER

The outdoor Thermo-hygro transmitter works with 2 x AA IEC LR6,

1.5V batteries. To install and replace the batteries, please follow the

steps below:

1. Uninstall the rain cover of the transmitter.

2. Remove the battery compartment cover.

3. Insert the batteries, observing the correct polarity (see the

marking in the battery compartment).

4. Replace the battery cover and the rain cover onto the unit.

Note: When changing batteries in any of the units, all units need to be reset by following

the setup procedure. This is because the thermo-hygro sensor will assign a random

security code at start-up and this code must be received and stored by the weather centre

in the first several minutes of power being supplied to it.

HOW TO INSTALL AND REPLACE THE BATTERIES IN THE WEATHER

CENTRE

The Weather Centre works with 2 x C, IEC LR14, 1.5V batteries. When the batteries need

to be replaced, the low battery symbol will appear on the LCD.

To install or replace the batteries, please follow

the steps below:

1. Remove the battery compartment cover.

2. Insert the batteries observing the correct

polarity (see the marking in the battery

compartment).

3. Replace the battery cover.

HOW TO INSTALL AND REPLACE BATTERIES INTO THE RAIN SENSOR

(OPTIONAL- SOLD SEPERATELY)

To install and replace the batteries, please follow the steps below:

1. Unlock the main cover from the rain sensor base and remove the cover.

2. Remove the battery cover at the top of the rain sensor.

3. Insert 2 x AAA IEC LR3 1.5V batteries into the battery compartment, observing the

correct polarity.

4. Replace the battery cover and the main cover on the unit.

Note: When changing batteries in any of the units, all units need to be reset by following

the setting up procedure. This is because the thermo-hygro sensor and rain sensor

(optional) assign a random security code at start-up and this code must be received and

stored by the Weather Centre in the first 135 seconds of power being supplied to it.

Note: The stored history records will not be retained after battery change or whenever

battery is removed from the Weather Centre.

tendency indicator and battery indicators.

3. Air pressure history, relative air pressure, rainfall data (optional)

*When the Weather Centre successfully receives the transmission signals, the icon will

be switched on. (If not successful, the icon will not be shown on the LCD). User can

therefore easily see whether the last reception was successful (“ON” icon) or not (“OFF”

icon). On the other hand, the short blinking of the icon shows that a reception is

being done at that time.

POSITIONING:

Using 915MHz wireless transmission gives users little restriction on placement because all

units can be positioned virtually anywhere within a 330 ft / 100 meters radius of the base

station. Please ensure that the cable included in this set meets your distance

requirements (see accessories in the main user manual for adding extension cables).

Important: Ensure all signals can be received and/or all cable distances meet with your

requirements at the point of fixing particularly before you start drilling any mounting holes.

Wind sensor

Secure the main unit to the shaft of the mast holder using the single screw provided with

the front of the sensor (marked E) facing in the East-West direction otherwise wind

direction will not be accurate. Now fix the entire unit to a suitable mast using the U-bolt,

washers and nuts found in this set.

Note: For best results mount the wind sensor onto a mast to allow the wind to freely travel

from all directions to enable an accurate reading (ideal mast size should be from Ø 5/8” to

11/4”). Ensure that the cable of the wind sensor meets your distance requirements

Thermo-hygro Sensor

To wall mount the thermo-hygro sensor, fix the wall holder onto the desired wall (2 screws

are supplied), plug the sensor firmly into the wall holder and then carefully replace the rain

cover back over the thermo-hygro sensor.

Note: After mounting the units, should the weather data not be received, user may need to

remove the batteries from all units and redo the set-up procedures after about 5 minutes.

Rain sensor (optional)

The rain sensor should be mounted horizontally about 2-3ft off from the ground (or higher)

in an open area away from trees or other coverings to allow rain to fall naturally for an

accurate reading.

Note: For best results ensure the base is horizontal to allow maximum drainage of any

collected rain

or duplicated or processed using electronic, mechanical or chemical procedures without

written permission of the publisher.
