WSX53A Precipitation (Rain, Snow, Sleet, Hailstone) Detector

WSX53A replaces the WSX43. It detects all forms of precipitation (rain, snow, hail, sleet). Furthermore it is able to discriminate between rain and snow. It has two volt-free contacts which are activated in response to precipitation and snow-point temperature respectively. A post event delay can be applied to delay contact deactivation by 15, 30 and 45 minutes. The detector is used for automatic activation of shutters, heaters, blowers, etc, in response to precipitation.
