Automatic Snow/Ice Melting System Controller
Automatic Snow/Ice Melting System Controller - APS-3C
In conjunction with up to six sensors residing in target zones, the microprocessor-based APS-3C provides effective, economical auto-matic control of snow melting applications for walkways, ramps, driveways, gutters and downspouts. Operating at either 120 volt or 208-240 volt, 50/60 Hz, the APS-3C’s DPDT output relay switches 24 Amp heater loads or directly operates both mechanically and electrically held remote contactors.
Automatic Snow/Ice Melting System Controller - APS-4C
The patented APS-4C provides effective, economical automatic control of snow melting systems including those for gutter and down spouts. The ability to use multiple sensors ensures optimum control of large systems. Supply voltage options include 277 volt single-phase, 208-240 volts 3 phase, or 277/480 volt 3 phase, with a contactor rating of 50 amps per pole. The integral ground fault circuit interrupter with a test/reset facility ensures safety along with NEC and local code compliance. The APS-4C operates up to ten SC-40C Satellite Contactors for larger loads.
Configurable Aerial Snow Melting Controller - LCD-8
The Snow Switch Model LCD-8 configurable aerial snow melting controller 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 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 100 VAC – 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 using just two part numbers.
It 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 redesigned, patent pending, 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, which are susceptible to damage, or the need to open the enclosure.
Verifying system functionality after installation or when troubleshooting used to require spray circuit cooler or ice for controller activation. The Sno-Test™ feature eliminates this need by performing 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.
Snow Melt Mats and Snow Switch
Each roll of sturdy mesh has a 3″ pre-spaced thick heating wire for embedding in concrete, asphalt, or under pavers. The mats come in 2′ width, providing 50 watts per square foot.
