If "QUIT" is selected, the user is
prompted with a screen asking if it is
desired to re-baseline the control.
Baselining the control is intended as a means to save
performance data at the time when the control is
operating optimally. The baseline values are a "trend" of
the first 500 cycles following an installation or a
command to "re-baseline" and is provided as a method
to compare present burner performance to that when the
burner was initially installed or serviced. Using the
baseline data, it is possible to monitor the burner system
for degradation and allow a service person to address
any issues before they result in a no-heat situation. After
performing the service it may be desired to reset the
baseline through the installer setup menu.
NOTE: Re-baselining will establish new baseline values
for CAD cell and Ignition Time going forward. It
will also reset the "Cycles Since Baseline",
"Lockouts Since Baseline", and "Recycles Since
Baseline" counters back to zero.

Limit inputs. Note that "TT Remote"
means EnviraCOM™ is commanding
the R7284 to behave opposite the
status of the TT terminals.

The history screens can provide useful information about
the controls past performance, including its recent
history such as cycle trends (using the baseline function)
and total cycles since installation.
