LCD-8 Ice Dam Prevention Sensor


The LCD-8 aerial-mounted sensor/controller senses snow conditions and can distribute power to heating cables for the prevention/control of ice dams on roofs and in gutters (120V/240V).

  • For roof and gutter de-icing and snow melting applications
  • Built-in temperature and moisture sensor for reliable snow detection
  • Adjustable hold-on timer (max 5 hours) to ensure complete melting of snow/ice
  • Adjustable temperature set point
  • Max 16 amp load
  • 120V or 240V
  • Simple solution for most residential and light commercial snow melting needs

Snow melt system controls just got configurable. Along with ETI’s legendary CIT-1 aerial sensor, the Snow Switch LCD–8 with its configurable magnetic switch, makes automatic snow melting a cost effective alternative in even the smallest applications.

Heaters operate at temperatures below the set-point, 38°F (3.3°C) default, only when required. The adjustable hold-on period, 3 hours default, continues heater operation after snow stops to ensure complete melting.

The LCD–8 controller’s internal magnetic reed switch is used to trigger manual heater cycling and to configure the system’s temperature set-point and hold-on time. The LCD–8 controller operates from either the automatically selecting 100VAC – 240VAC unit, part number 24619, or from the 24VAC unit, part number 24781. The distinct voltage options, along with their configurable temperature set-point and hold-on time functions, are engineered to address a broad number of applications from just two SKUs.

The LCD–8 controls heater loads up to 16 amps resistive or 3 amps inductive. The operating temperature range is –40°F to 140°F (–40°C to 60°C). The redesigned, patent pending, rugged polycarbonate enclosure provides excellent protection at temperature extremes and allows snow to fall away, preventing “iglooing” over the moisture sensor.

The internal magnetic reed switch allows for both configuration and manual heater operation without the  need for external switches—which are susceptible to damage—or opening the unit.

Before the LCD-8, verifying system functionality after installation or troubleshooting used to require ice or circuit cooler spray for controller activation. Today, the LCD–8’s Sno-Test feature performs a self-test after power application, operating heaters in a unique pattern for a few seconds. Reading the test results takes only an AC voltmeter or clamp-on ammeter.
