Lockouts
A lockout is indicated when “Loc” is displayed at the top-left of the screen; the specific lockout code/number is
displayed in large text to the right, see Figure 17-5. Some lockouts (e.g. Loc 1 and 2) are considered “hard
lockouts”, meaning the lockout cannot be cleared by cycling the power supply off and on; the lockout can only be
cleared by pressing and holding the RESET button on the display console. While the boiler is in lockout, the User
and Installer Menus are still accessible as before, and may be accessed to identify boiler sensor readings and
settings.

Blocking Errors
A blocking error is indicated when “Err” is displayed at the top-left of the screen; the specific error code/number
is displayed in large text to the right, see Figure 17-6. Blocking errors are only displayed while a problem exists;
during which time the burner is not permitted to operate. To clear a blocking error the problem must be corrected,
i.e. the blocking error will not be cleared by cycling the power off and on, or by pressing the RESET button.
While the blocking error is display, the User and Installer Menus are still accessible as before, and may be
accessed to identify boiler sensor readings and settings.
