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
L L L L L L L L L L

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.
