Alecto WS-4800 - Wind Direction & Speed; Temperature Comfort Indices

11
4.7 Wind (direction + speed):
1. actual wind direction
2. measured wind directions (max 6) of the
last 5 minutes
3. wind direction
4. indicates whether the displayed wind
speed is an average speed or a wind gust
(*9)
5. Wind speed
6. indicates whether the wind speed is
expressed in mph (miles per hour), in m/s
(meters per second), in km/h (kilometres
per hour) or in Knots (1 KNOTS = 1,852
km/h (1.151 mph)) (*10)
7. illuminates when the max. wind speed
alert is set
8. wind speed, according to the Beaufort scale
9. wind speed, expressed in everyday
speech (*11)
*9: AVERAGE = average speed
GUST = wind gust
You can switch between these indications
  bybrieypressingthe button.
*11: STORM=≥88km/h(≥55mph)
STRONG = 42-87 km/h (26-54 mph)
MODERATE = 14-41 km/h (9-25 mph)
LIGHT = 3-13km/h (2-8mph)
4.8 Feels like / Wind chill / Heat index / Dewpoint:
1. indicates whether the displayed
temperature is the Feels like, Wind chill,
the Heat Index or the Outdoor Dew Point
(dew point temperature, outside (*12)
2. temperature according to the indication shown underneath 1 (*13)
3. effect of Wind chill and Heat index on Feels like temperature
*12:
Feels like: temperature compensated with the wind chill or heat index
Wind chill: combination of the measured temperature and wind speed
Heat index: combination of the measured temperature and air humidity
Dew point temperature, outside: the temperature at which water vapour is converted into water (mist,
dew or frost). This temperature depends on the outdoor temperature and the humidity.

*13: At HEAT INDEX: the alert level is:
< 27°C (display ‘LO’) no danger
27°C – 32°C (80°F – 90°F) pay attention (risk of exhaustion due to heat)
33°C – 40°C (91°F – 105°F) be careful (risk of dehydration due to heat)
41°C – 54°C (106°F – 129°F) danger (increased risk of exhaustion due to heat)
  ≥55°C(≥130°F) verydangerous(hugeriskofdehydration/stroke)
*10: You can set the desired unit as follows:
1. press and hold the button for 2 seconds
2. use / to select your desired unit
3. briefly press the button
