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 re, electrical shock and/or result in

snow build-up.

1. This is not a “do-it-your-self” product. A qualied

electrician must install the SA-1.

2. If after carefully reading these instructions you still

have questions regarding installation, operation or
maintenance of this product, call the numbers listed
for assistance.

3. Prior to installation, check the SA-1 body enclosure or

wires for possible shipping damages. Do not install a
damaged SA-1 controller.

4. All heating cables, controls & associated systems must

be installed in compliance with the latest editions of
all applicable electrical codes and ordinances.

5. These instructions must be saved and made available

to owners or users of this product and/or transferred
to future owners.

6. Any heating cable that is to be connected to the SA-1

must be installed according to the manufacturer’s
instructions.

7. Do not connect mo re than 16 Amp load to the

SA-1 (See Fig. 2 & 3). Risk of re, electric shock or

accumulation of snow can result from a larger cable
or from multiple cables being connected.

8. Secure the SA-1 in an area free of obstructions such
as trees, shrubs, etc. to prevent any damages to the
snow sensor.

9. Avoid excessive shock or vibration.

10. Do not touch the surface of the moisture sensor, it is
a hot surface.

INSTALLATION INSTRUCTIONS

1. Mount the SA-1 securely in upright position in an
open space, in direct contact with snowfall pattern
with a .5" (12.70mm) NPT mounting connector.
The unit is water-resistant, but it is not designed
to be submerged or immersed in water. Ensure
that the mounting location is close, less than

2.5 ft (76.20cm) to the electrical junction box.
See Fig. 4a &4b.

*Electrical code may require use of a ground fault protection device.

2. The SA-1 can be connected to the building power
supply as per Fig. 2 or Fig. 3. Before connecting the
controller to the electrical power supply, consult
the local, state or provincial, and national electrical
code. The electrical code may require a Ground
Fault Protection device to be used.

3. Ensure that all pipe connections are sealed to
prevent any penetration of water inside of conduit
or electrical junction box.

Automatic Snow/Ice Melting Controller — Installation & Operation Instructions sa-1 3

OPERATION INSTRUCTIONS

The SA-1 snow melting control is designed to energise
the heating cable only when snow or ice conditions exist
and there is risk of freezing. If the temperature is below 3°C
(38°F) and snow is falling, the controller will apply power to
heating cable. The cable remains energised until 2.75 hours
after the snow stops. The delay is necessary to ensure the
heated area dries. If at any time the snow starts falling
again the controller restarts the heating cycle.

In spring or fall when the snow conditions are not very
heavy, the controller may switch on the heated area. For
this situation we recommend having a manual switch
connected in series with the SA-1 to turn it off.

In wintertime the wind may cover the heated area with
snow. The SA-1 can not sense this situations and will not
energise the heating cable. Putting snow on the sensor
surface can energise the SA-1.

The SA-1 may be tested for functionality if the outside
te mp er at ur e is b el ow 25° C (7 7° F) , Submer ge t he
temperature sensor into a glass with ice water for 5 to
10 minutes, wet the surface of the moisture sensor, the
SA-1 should energise the heating cable. After this test,
dry off the sensor, disconnect the power for one minute
and then reconnect it back. The cables should remain
deenergised.

Every year, in the fall the SA-1 must be inspected for
physical damage and to clean up the snow sensor surface.
To clean the snow sensor surface:

1. Disconnect SA-1 from the power supply.

2. With a clean, soft bristle tooth brush clean up the surface

of the snow sensor.

3. Reconnect SA-1 to the power supply.
