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 val-
ues for CAD cell and Ignition Time going for-
ward. 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.

If NO is selected, "i" returns to the

If YES is selected, "i" continues
through diagnostic screens.
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.

View History
From the Diagnostic screen scroll to the View History
screen and select YES. Scroll through the
performance data by using the up or down buttons.
Pressing "i" during any of the CAD cell screens moves
to the Ignition Time screens below.
Pressing "i" during any of the ignition time screens
moves to the Cycle Count screen below.
The next press goes back to the View History screen
where the user can exit to the home screen or loop
back through the performance history again.
Error History Screens
For all Error History screens, pressing "i" returns to the
Normal Screen.
From the home screen, press the up button to display
most recent error.
Press the up button again to proceed to the next most
recent error or the down button to return to the
previous error screen.
These three screens transition every 3 sec.
If no more errors are logged, the display shows "Error
History End."
