After inserting the batteries, all the segments on the LCD will light up briefly before displaying the time and all the other modes.

Note:

Please check that the outdoor temperature is received on the LCD. Should the signal not be received, then see Checking for 433MHz reception below.

Indoor temperature reading:

The indoor temperature is displayed underneath the time and will automatically appear after few seconds when the batteries are inserted.

Minimum and maximum indoor temperature recordings:

Underneath the current indoor temperature readings are the minimum and maximum indoor temperature recordings. This feature is useful for displaying the recorded

temperatures of the room where the Weather Station has been placed. When a new temperature low or high is reached, it will be automatically updated and displayed.

Relative humidity reading with comfort level reading (face icons)

The relative humidity with comfort level reading is displayed underneath the indoor temperature. With this feature, users can determine how comfortable the reletive humidity

is within their current surroundings. Again, as with the indoor temperature, the relative humidity reading will automatically be taken once the batteries are inserted.

Working together with relative humidity, the Weather Station will register a comfort level reading by representation of a “☺““Smilling“ face or “ꢀ““Sad“ face. The temperature

range between +68ºF to +78.7ºF and relative humidity range between 45% to 65% will register the “Smilling“ face. The “Sad“ face will appear should either the temperature

or humidity readings be outside these set level and the “Sad“ face represents un uncomfortable one.

When the “ꢀ““Sad“ face appears with the word “DRY“ or “WET“, it means that the relative humidity reading is outside its comfort range. However, “DRY“ or “WET“will not

appear if only the temperature reading is outside its comfort level range. The “ꢀ““Sad“ face and “DRY“ will appear of the relative humidity level is below 45% or “WET“ will

appear if the level is above 65%.

Weather tendency icons

There are 3 weather icons on the fourth line of LCD which can be displayed in any one of the following combinations:

Cloudy with sunny

intervals

Rainy

Sunny

For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather. If the icons do not change, then it

means either the air pressure has not changed or the change has been too slow for the Weather station to register. However, if the icon displayed is a sun or raining cloud,

there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes.

The icons displayed forecasts the weather in terms of getting better or worse and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is

cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather

is expected to get worse but not necessarily rainy.

Note:

After setting up, readings for weather forecasts should be disregarded for the next 12-24 hours. This will allow sufficient time for the Weather Station to collect air pressure

data at a constant altitude and therefore result in an more accurate forecast.

Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature is estimated to have an accuracy level of about 75% due to the

varying areas the Weather Station has been designed for use in. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather Station

will be more accurate compared to use in areas where the weather is stagnant most of the time (for example mostly sunny).

If the Weather Station is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the upper floors of a house),

remove the batteries from both the Weather Station and transmitter and re-insert them after about 30 seconds. By doing this, the Weather Station will not mistake the new

location as being a possible change in air-pressure when really it is due to the slight change of altitude. Again, disregard weather forecasts for the next 12 to 24 hours as this

will allow time for operation at a constant altitude.

The weather tendency indicator

Working together with the weather icons are the weather tendency indicators (located above and belowthe weather icons). When the indicator points upwards, it means that

the air-pressure is increasing and the weather is expected to improve, but when indicator points downwards, the air-pressure is dropping and the weather is expected to

become worse.

Taking this into account, one can see how the weather has changed and is expected to change. For example, if the indicator is pointing downwards together with cloud and

sun icons, then the last noticeable change in the weather was when it was sunny (the sun icon only). Therefore, the next change in the weather will be the cloud with rain

icons since the indicator is pointing downwards.

Note:

Once the weather tendency indicator has registered a change in air pressure, it will remain permanently visualized on the LCD.

Storm warning indicator:

The downward tendency indicator will flash if the air pressure has dropped by 4 hPa or more in the last 6 hours.

Relative air pressure inHg

Underneath the weather icons is the air pressure reading which is recorded constantly in inHg and the Weather Station displays this reading as the relative air pressure.

Air pressure history (electronic barometer with barometric pressure and trend)

Air pressure over

the last 72 hours

Air pressure scale

(Each bar represents one hPa (millibar); 0.03 inHg (inches of mercury) = 1hPa)

The bar chart indicates the air pressure trend over the last 72 hours in 8 steps, 0, -1, -3, -6, -12, -24, -48 and -72 hours. The bar is plotted at each of the right (0, ±1, ±3, ±5,

and ±7) compares the result. The “0“ in the middle of this scale is equal to the current pressure and each change (±1, ±3, ±5, and ±7) is how high or low in “hPa“ the past

pressure was compared to the current.

If the bars are rising, it means that the weather is getting better due to the increase of air pressure. If the bars go down, it means the air pressure has dropped and the weather

is expected to get worse from the present time “0“.

Note:

For accurate barometric pressure trends, the Weather Station should operate at the same altitude for example, it should not be moved from the ground to the second floor of

the house. Should the unit be moved to a new location, reset both the transmitter and Weather Station as this will prevent the slight change in lication registrering as a

possible change in air pressure.

After the resetting or setting up, weather readings should be discarded for the next 12 to 24 hours as this will allow sufficient time for the Weather Station to operate at a

constant altitude and thus enabling a more accurate reading.

Outdoor temperature reading

The outdoor temperature is displayed underneath the weather icon section. The Weather Station will automatically start scanning for the transmitter’s 433MHz signal after the

batteries are inserted and once received, the outdoor temperature will appear on the LCD.

Minimum and maximum oudoor temperature readings

Underneath the current outdoor temperature, are the outdoor minimum and maximum temperature recordings. When a new temperature low or high is reached, it will be

updated and recorded into the Weather Station memory.

Automatic minimum and maximum indoor and outdoor temperature resetting

The Weather Station is programmed to automatically reset the indoor and outdoor minimum and maximum temperature recordings once a day. The maximum temperatures

are reset at 8:00am and the minimum temperatures at 8:00pm.

Note:

There is also a reset button located on the front of the unit for manual resetting of minimum and maximum temperatures (see Manual resetting temperature below)

Manual resetting of minimum and maximum temperatures

The minimum and maximum temperatures of the Weather Station can also be reset manually anytime by simply pressing the RESET key on front on the unit. Once the

RESET key is pressed, the data updates to the current indoor and outdoor temperatures.

Note:

Although the minimum and maximum temperature have been reset manually during the day, the Weather station will still be programmed to reset all minimum and maximum

temperatures once a day.

Checking for 433MHz reception

The Weather Station will automatically start scanning for the 433MHz signal after the batteries are inserted. If the outdoor temperature is not displayed after about 30 seconds,

then check the following list before resetting the units (see Resetting below):

The distance of the receiver or transmitter should be at least 1.5 to 2 meters away from any interfering sources such as computer monitors or TV sets.

Avoid placing the receiver onto or in the immediate proximity of metal window frames.

Using other electrical products such as headphones or speakers operating on the same signal frequency (433MHz) may prevent correct signal transmission and

reception.

Neighbours using electrical devices operating on the 433MHz signal frequency can also cause interference.

Note:

When the 433MHz signal is received correctly, do not re-open the battery cover of either the transmitter or Temperature station, as the batteries may spring free from the

contacts and force a false reset. Should this happen accidentally then reset all units (see Resetting below) otherwise transmission problems may occur.

The transmission range is around 25 m from the transmitter to the Temperature station (in open space). However, this depends on the surrounding environment and

interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Resetting below).

The transmitter’s transmitting range may be affected by exposure to extreme cold condition (-25°C) for long periods of time due to the nature of Alkaline batteries. Should this

happen, the 433MHz signal may be weakenend and therefore result in a shorter transmitting distances caused by temperature level.

Resetting:

Remove batteries from both the outdoor transmitter and the Temperature station.

Wait at least 30 seconds and then repeat the procedures specified in Setting up (above).

Note:

Always wait at least 30 seconds after removing the batteries before reinserting, otherwise start up and transmission problems may occur. Also, remember when insertting, that

both units have to reset and to always reinsert the batteries to the transmitter first.

Positioning the temperature transmitter:

TheTemperature Transmitter is supplied with a holder that may be attached to a wall with the three screws supplied. To attach to the wall, please follow the steps below:

Mark the wall using a pen through the holes in the holder to obtain the exact drilling position.

Drill holes in the wall at the points marked.

Screw holder onto wall.

There is also double sided tape included with the wall mount. This can be used instead of drilling. Please mount this on a smooth surface instead of

a brick one. The surface can, however, affect the transmission range, for example: if the unit is attached to a piece of metal, it may then either

reduce or increase the transmitting range. For this reason, we recommend not placing the unit on any metal surfaces or in any position where a

large metal surface is in the immediate proximity (garage doors, double glazing etc.). Before securing in place, please ensure that the Temperature Station can receive the

signal from the Temperature Transmitter at the positions that you wish to situate them. The Temperature Transmitter clicks in or out of the holder easily. When inserting or

removing the Temperature Transmitter from the wall holder please hold both units securely.

Positioning the Weather Station:

For wall mounting, please check that the outdoor temperature can be received outdoors from the desired locations. To wall mount:

Fix a screw (not supplied) into the desired wall, leaving the head extended out by about 5mm.

Using the Weather Station’s hanging hole, carefully hang it onto the screw. Remember to ensure that it locks into place before releasing.

Important notes:

•

Avoid placing the units where they can be exposed to sudden changes in temperatures; i.e. direct sunlight, extreme cold and wet/moist conditions. This will help avoid

any inaccurate readings and any possible damage to the unit.

•

Should the unit be exposed to extreme and sudden temperature changes, it will lead to rapid changes in its forecast reading and thereby reduce its accuracy.

Should the unit be moved to another location that is significantly higher or lower than its standing point (for example from the ground floor to the first floor of a house),

then either reset the units or discard the readings weather forecasts for the next 12-24 hours. By doing so, this will allow allow sufficient time for the unit to operate at a

constant altitude and thus enabling a more accurate forecest.

Care and Maintenance:

•

Extreme temperatures, vibration and shock should be avoided as these may cause damage to the unit and give inaccurate forecasts and readings.

When cleaning the display and casing, use a soft damp cloth only. Do not use solvents or scouring agents as they may mark the LCD and casing.

Do not submerge the unit in water.

Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended size.

Do make any repairs to the unit. Return it to its original point of purchase for repair by a qualified engineer. Opening and tampering with the unit may invalidate its

guarantee.

•

Do not expose the unit to extreme and sudden temperature changes, this may lead to rapid changes in forecasts and readings and thereby reduce its accuracy.

Battery Change:

It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of these units.

Please participate in the preservation of the environment. Return used batteries to an authorised depot.
