The LCD-1H & 3H Snow Switch saves energy by providing snow melting only when
required during snowfall and for a time thereafter to ensure complete melting.
As heavy, wet spring and autumn snow often occurs above freezing, the LCD-1H &
LCD-3H detects precipitation as snow at temperatures below 38degF (3.3degC).
The LCD-1H's internal, isolated 3 amp relay contact remains closed for a 5-hour
hold-on time after snowfall stops to ensure complete snow melting and pavement drying.
The LCD-3H remains closed for 1-hour hold-on time.
The LCD-1H & 3H Snow Switch achieves high performance at low
cost through microprocessor control. Members of the LCD product family
have provided more than 70 million hours of reliable snow melting
