Airmar WeatherStation WS-220WXH includes 60w heater

The heater may be used to prevent the formation of dew or ice on the aluminum plate in the wind channel. If the Heater Mode is set to Automatic, then the WeatherStation will automatically cycle the heater on and off over time to keep the plate temperature within appropriate limits based on the air temperature and dew point temperature.

Note that when the heater is on, the air temperature sensor within the unit will be heated by the heater and will not provide an accurate indication of outside ambient air temperature. If an accurate air temperature is desired, you should consider using a separate temperature sensor in conjunction with the WeatherStation. This model with heater must be used with one of the special heater-compatible NMEA 0183 cables. It cannot be used with an NMEA 2000 cable.
