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
snow build-up.
