Setpoints
The
two
Setpoints
are
deactivated
by
default
(alarm
mode).
Activating
and
adjusting
the
Setpoints
is
accomplished
through
software.
Once
one
or
both
Setpoints
are
activated
the
relay
changes
state
as
the
current
temperature
passes
the
setpoint
temperature.
6.2.10
Deadband
Deadband
is
a
zone
of
flexibility
around
the
Setpoint.
The
alarm
does
not
go
abnormal
until
the
temperature
exceeds
the
Setpoint
value
by
the
number
of
set
deadband
degrees.
Thereafter,
it
does
not
go
normal
until
the
temperature
is
below
the
Setpoint
by
the
number
of
set
deadband
degrees.
The
Deadband
is
factory
preset
to
±
2°
C
or
F
of
Setpoint
value.
Adjusting
to
other
values
is
accomplished
through
software.
For
information
on
the
sensor’s
communication
protocols,
see
section

Programming
Guide
on
page

The
following
figure
is
an
example
of
the
Deadband
around
a
Setpoint
temperature
of
960°C
(1760°F).
