data to the base station. Operating power is taken from the thermo-hygro sensor by a cable connection

3. Set up Guide

3.1 Battery install

Setting up using batteries:

Note: To avoid operating problems, please take note of battery polarity before/when inserting any

Alkaline Batteries (permanent damaged could be introduced by inserting the battery in wrong

direction). Use good quality Alkaline Batteries and avoid rechargeable batteries.

1) Pull away the shower proof casing of the thermo-hygro sensor to reveal the two sockets (for the wind

sensor and rain sensor)

2) Connect the attached cables of wind and rain sensors to the corresponding sockets of the thermo-hygro

sensor by clicking them into place. Make sure that rain and wind sockets not swapped when plugging the

phone jacket.

3) Open the base station’s battery cover located at the back of the unit and insert 3 x AA, 1.5V Alkaline

batteries into the battery compartment and close the battery cover

4) Open the battery cover of the thermo-hygro sensor located below the two sockets and insert 2 x AA, 1.5V

Alkaline batteries and close the cover

Every time the thermo-hygro sensor is powered up (for example after a change of batteries), the LED

indicator will light up for 4 seconds. The sensor will transmit weather data within the first 24s, and then the

sensor will start radio controlled time reception. During the RCC time reception period (maximum 5 minutes),

no weather data will be transmitted. The LED indicator will be blinking 5 times once RCC signal were

received. The LED indicator will not light again after RCC reception is successful. Regular RF link will be

established once RCC reception routine is finished.

When the base station is powered up, a short beep will sound and all LCD segments will light up for about 3

seconds before it enters into learning mode to learn the sensors security code. After the learning mode the

base station will start the radio controlled time reception.

Note: DO NOT PRESS ANY KEY during the first 10 minutes learning period or before radio controlled time is

displayed. After both outdoor weather data and radio controlled time are displayed you can place your remote

sensor outdoors and set your time (if no RCC reception is possible). If there is no temperature reading in the

indoor station, make sure the units are within range of each other or repeat the battery installation procedure.

If a key is pressed before the weather station receives the temperature signal, you will need to follow the

battery installation procedure again. Please wait minimum 10seconds before re-insert the battery again

to make a proper reset for both transmitter and receiver..

Note : If a battery change on the transmitter side happened, the base station will be resynchronized to the

transmitter within the next 3 hours. If you want to shorten the receiving data time, the base station has to

re-install the battery so that it can have the new security code learnt right way, however the previous data in

base station will be lost.

Note for Radio Controlled Time WWVB:

The time and date display is based on the signal provided by the highly accurate government operated

atomic clock. WWVB signal reception is on every even hour even the reception is successful. If reception has

been successful, the received time and date will overwrite the manually set time and date.

4.2 Weather forecasting

Sunny Partly Cloudy Cloudy Rainy

The four weather icons Sunny, partly Cloudy, Cloudy and Rainy represent the weather forecasting. For every

sudden or significant change in air pressure, the weather icons will update accordingly to represent the

change in weather.

4.3 Weather forecast tendency indicator

The weather tendency indicators arrow is located between the weather icons to show the air pressure

tendency and provide a forecast of the weather to be expected by the decreasing or increasing air pressure.

The rightward arrow means that the air pressure is increasing and the weather is expected to become better.

The leftward arrow means that the air pressure is decreasing and the weather is expected to become worse.

The change of weather forecast icon is in accord to the relationship between current relative pressure and

the pressure change since last three hours. If the weather is changing, weather tendency indicator (animated

arrows) will be flashing. And then the arrows will fix while weather conditions have become stably.

Examples of changing weather icons:

4.4 Storm warning indicator

The storm threshold can be set to suit the user’s requirement for storm forecasting from level 3-9 (default

level 3). When there is a fall over pressure threshold in 3 hours, the storm forecasting will be activated, the

clouds with rain icon and tendency arrows will flash for 3 hours indicating the storm warning feature has been

activated.

Notes to pressure sensitivity setting for weather forecasting:

The pressure threshold can be set to suit the user’s requirement for weather forecasting from level 2-4

(default level 3). The lower level pressure threshold setting, the higher sensitivity for weather forecasting. For

areas that experience frequent changes in air pressure requires a higher setting compared to an area where

the air pressure is stagnant.
