• Postpurge time
• Valve proving when option (when valve proving is executed)
• Valve proving time
Postpurge time specifies how long the burner should be purged after it leaves the "RUN"
state. Valve proving (VP) is a feature that provides a systematic way of testing the valve seat
integrity to assure the valves are indeed closed when the system is off-line or idle.
Fig. 65. Enter commissioning
If the burner control is not in a state that permits commissioning to proceed, the
commissioning setup menu displays this fact, but does display the current parameter
settings (see Fig. 66). Only action permitted in this case is to press the left arrow button to
exit the menu and return back to the Display setup menu page.
Fig. 66. Commissioning not permitted
When commissioning is allowed the user has the option to continue on with commissioning
by selecting the "Yes" command or to exit the menu and not do commissioning with the
"No" command. The right and left arrow buttons tab between the two options. Pressing the
OK button executes the highlighted command. If "No" is selected, control returns back to
the page that it originated from (Home or Display Menu). If "Yes" is selected, the user is
requested to log into the burner control module with the commissioning password (see Fig.
67).
Fig. 67. Commissioning login
The commissioning password is "78". The password is entered by scrolling the digits to "78"
using the up and down arrow buttons when in the digit positions. The right and left arrow
buttons navigate between the digits and the "Yes" and "No" commands. When the input
focus is on the "Yes" and "No" commands the up and down arrow buttons tab between
these two options. Pressing the OK button when the input focus is on "Yes" or "No" executes
the command. A "Yes" command sends the password to the burner control module to
begin commissioning. A successful login transitions to the first commission page. An
unsuccessful login (wrong password) displays an "INVALID PASSWORD" message (see Fig.
68). If the "No" command is selected, commissioning is canceled and control returns to the
previous page.
