Snow Switch LCD-8

The Thermal-Flex Snow Switch Model LCD-8 is a configurable aerial snow melting controller that makes automatic snow melting a cost effective alternative for 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 operates from either an automatic selection of 100 VAC to 240 VAC, or from 24 VAC. These two voltage options combine with the configurable hold-on time and temperature set point to meet the need of a wide number of applications.

The LCD-8 controls heater loads up to 16 amps resistive or 3 amps inductive. The operating temperature range extends from -40° F to 140° F (-40° C to 60° C). The rugged polycarbonate enclosure provides excellent protection at temperature extremes while allowing snow to shed to prevent iglooing over the moisture sensor.
The internal magnetic reed switch allows for both configuration and manual heater operation without the need for external switches. The unit includes a self-test feature to help verify system functionality or when troubleshooting.
