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 17-6. 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

While the blocking error is display, the User and Installer Menus are still accessible as before, and may be
