The Burner commission reset page is displayed for the final step of the commissioning
procedure. After all configuration and confirmations are done the RESET button on the
burner control module must be pressed and held for 5 seconds. This page (see Fig. 75)
automatically displays when the burner control module wants this reset action to be
performed.

After the RESET button has been held for 5 seconds the burner control module indicates
that commissioning is successfully done (see Fig. 76). The left arrow or OK button can be
pressed to exit commissioning and go back to the commissioning menu.

Each step of the commissioning procedure must be performed within 30 seconds after
the page is displayed for the step. If the RESET button is released too early (less than
5 seconds) or the user doesn't respond to a procedure step within 30 seconds, the
commissioning session is terminated by the burner control module and this failure is
indicated on the page (see Fig. 77 for an example).
Fig. 77. Failed commissioning step
The user has the option to restart commissioning or not if the session fails to end
completely. The "Yes" option is selected and the OK button pressed to redo commissioning
by logging in again (see Fig. 67). The "No" option is selected and the OK button pressed
to not redo commissioning which exits this page and returns back to the commissioning
menu to show the current settings (see Fig. 64). The right and left arrow buttons are used to
tab between the "Yes" and "No" options.
