9. Install Activation Device
Heatizon activation devices come with data sheets, wiring diagrams, and instructions.
Install the selected activator by carefully following the specific set of instructions that were
included with the activation device. Some systems are professionally designed and can
include custom wiring diagrams from our industry professionals. There are three available types of
activators that are suitable for SnowMeltz®:
• MANUAL
- Manual activators usually consist of a timer switch that keeps the
system on for a set amount of time, then powers off the system. This activator
requires some sort of panel (regardless of the number of circuits) to switch the load.
• AERIAL
- These activators are mounted on a wall or on a conduit in the air in very
close proximity to the area to be heated. They can be equiped with temperature
and/or moisture sensors, and usually have some form of basic manual over-
ride. Depending on the model, it may be able to switch smaller loads (30
amps) without the use of a panel. The sensor for this device must be able
to detect the same circumstances that will be present in the area where the
SnowMeltz® is installed.
• REMOTE/IN-GROUND
- The activators usually have a head unit located
indoors and have more functionality and have optional in-ground sensors
that detect moisture/temperature on on the concrete/asphalt. These units can
also have separate remote temperature sensors. Normally these units require
a panel to switch the load. When using in-ground sensors, the conduit for
the sensor wire and head unit must NOT cross or come in contact with the
heating element. The sensor must be mounted in the SAME substrate as the
SnowMeltz® system is installed into. When using a remote temperature sensor,
it should be located to recieve the same conditions as the heated area.
It is imparative that any/all conduit being used (for sensors, cold leads, power, etc.) do NOT come
in contact with the heating element. Consult the individual instructions for the appropriate
activator for wiring/mounting. Quickstart/Wiring Diagrams for the most popular Heatizon
activation devices are included on pages 20-23 .
• If the selected activation device requires conduit for a temperature sensor, the
conduit must be centered between two runs of heating cable. Always run high
voltage and low voltage conductors in separate conduits.
• Heatizon recommends that photographs of the installed heating cable be taken and/
or hand drawings documenting the layout be completed prior to installing the final
surface.
