Snow Switch model LCD-8



Features & Benefits

  • Automatic snow and ice melting controller mini-mizes operating costs.
  • Automatic voltage selection operates from 100VAC – 240 VAC
  • Adjustable hold-on time and temperature set point provides flexibility for a wide range of applications.
  • Rated for up to 3 amp inductive loads for pilot duty applications and resistive loads up to 16 Amps.
  • Sno-TestTM automatic testing and manual heater cycle for system testing.
  • Simple four-wire installation.
  • C/UL/US-listed for temperature regulating equipment.


The Snow Switch Model LCD-8 confirgurable aerial snow melting controller makes automatic snow melting a cost effective alternative in even the smallest applications. Heaters operate at tem-peratures below the set point, 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 includes an internal magnetic reed switch used for manual heater cycling, as well as configuring the temperature set point and the hold-on-time.

The LCD-8 controller operates from either an automatic selecting 100VAC – 240VAC or from 24VAC. 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 using just two part numbers.

It controls heater loads up to 16 amps resistive or 3 amps inductive. The operating temperaturer ange extends from –40°C to 60°C. The redesigned, patent pending, rugged polycarbonate enclosure provides excellent protection at tem-perature 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 with-out the need for external switches – which are susceptible to damage – or the need to open the enclosure.

Verifying system functionality after installation or when troubleshooting used to require spray cir-cuit cooler or ice for controller activation. The Sno-TestTM feature eliminates this need by per-forming a self-test after power application, and operating heaters in a unique pattern for a few seconds. Reading the test results takes only an AC voltmeter or clamp-on ammeter.
