SA-1

Automatic Snow/Ice Melting Controller

Installation & Operation Instructions

GENERAL

The SA-1heating cable controller has been designed and manufactured for the sole intended use of controlling heating cables in residential and commercial snow melting applications such as: sidewalks, driveways, parking garage entrances and drive-through. The SA-1 uses microcontroller technology to reduce energy consumption by energizing the heating cable only when the right conditions of temperature and snowfall occur.

The main components of the SA-1are shown in Fig.1. The snow and temperature sensors detect snow or ice conditions and activate, through a power relay, a heating cable.

Another feature of SA-1 is the LED indicator light. This light turns red if the snow sensor is dirty and needs to be cleaned. The red light will switch off automatically when the snow sensor is cleaned. The LED turns green every time the power relay is activated and will switch off if the power relay is off.

Improper installation, use and/or maintenance of the

SA-1 can cause fire, electrical shock and/or result in Figure 1 snow build-up.
