Comfort indicator
The symbols of the comfort indicator (three different faces

) reflect the room climate with the weather station
operating according to the following table:

This shows that, depending on the relation between temperature and humidity, there are clearly delimited areas
where climate is defined to be comfortable or uncomfortable. For instance, we feel that humidity below 30% is too
dry at 25 °C temperature (e.g. heating is on) and above 60% we think it is sultry.
Daylight-saving time changeover
The integrated clock switches automatically from winter time to daylight saving time and vice versa as determined
by the European Union and legally anchored in Germany since 25
th
July, 1978. The switching to daylight saving time
takes place on the last Sunday in March. The clock is set ahead by one hour 2:00 am CET.
The clock is changed to winter time on the last Sunday in October. The clock is set back by one our at 3:00 am CET.
But since not all countries change clocks this way, you can deactivate the automatic clock change in the WS888.
