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 38°F (3.3°C). 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 control.
