Note: The hPa setting feature can be used in area where there may be constant changes in air pressure which do not necessarily reflect the changes in the weather. In such areas for example, the hPa might be set to every 3hPa (millibars meaning that there will be no change of weather icons if the air pressure does not drop or increase by at least 3hPa. For areas where the weather is stagnant, the hPa can be set lower.

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:

Sunny

Cloudy with sunny

Rainy

 

intervals

 

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.
