Folks,

With the success of our new DS-224 24VAC/VDC snow sensor we have added to our line again with the DS-824. The inner workings of the DS-224 and DS-824 are identical except the DS-824 provides an external status-indicating lamp and a remote precipitation grid as used on our DS-8. Along with our standard controls for trigger temperature and delay adjustment it also provides a selectable 30-90 minute drying cycle or a 2-6 hour drying cycle. A new control has also been added to allow precipitation sensitivity adjustment. When set for highest sensitivity the DS-824 will trigger immediately, just like our other units. When sensitivity is decreased, however, the sensor can ignore an occurrence of snow blown on to the grid from the roof or a drift or very light snow that doesn't justify activating the snow melt system. The sensor actually samples the precipitation grid and tracks how often snow is detected or not detected. When consistent snowfall is detected the sensor triggers. For more information visit our webpage at www.goase.com/ds824.htm to see if the new DS-824 will fit your application.
