Comfort indicator

The symbol of the comfort indicator (the three different "smiles" J K L) reflect the room climate whereby the weather station works according to the following table:

Temperature	air humidity
20%	30%	35%	40%	45%	50%	55%	60%	65%	70%

<64.4 °F

64.4- 67.8 °F

67.9- 71.4 °F

71.5- 75.0 °F

75.1- 78.6 °F

78.7- 82.2 °F

over 82.2 °F

One can thus see that depending on the relationship of the temperature to humid- ity, there are certain marked ranges that can be defined as comfortable or uncom- fortable climate. One would thus feel that at a temperature of 77 °F (25 ˚C) and a humidity of less than 30% is very dry (for e.g. air from the heaters) and one above 60% as sultry.

Daylight saving time switching

The integrated clock implements an automatic daylight saving time switching ac- cording to the regulations of the “Energy Policy Act of 2005”.
