WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when
exposed to live electrical components could result in
death or serious injury.
When it is necessary to work with live electrical
components, have a qualified licensed electrician or
other individual who has been properly trained in
handling live electrical components perform these
tasks.
Important: To prevent injury or death from electrocution, it
is the responsibility of the technician to
recognize this hazard and use extreme care
when performing service procedures with the
electrical power energized.
Symbio Controls
The Symbio™ 700 supports a Service Test Mode that can
be used to energize the various components of the system,
either to support general system startup tasks or to support
troubleshooting. The user can initiate Service Test Mode
through the controller user interfaces, including the Symbio
Service and Installation mobile application.
The modes shown below can be initiated. Depending on
the equipment configuration, the controller will energize the
appropriate outputs. A user-selected timeout value will
determine how long the controller will remain in any given
state once initiated. For detailed information on how each
Service Test State is interpreted based on the equipment
configuration, see ACC-APG002*-EN, Symbio™ 700 for
Precedent Packaged Rooftop Air-Conditioners Application
Guide.
