temperature and pressure (e.g., water flow rate, VS load duty cycle and the altitude)
sensors. If a:
Temperature sensor is not connected to the controller the text ‘n/c’ is displayed.
Pressure sensor is not connected to the controller, ‘0’ is displayed.

Errors are triggered when a sensor detects that the boiler is operating outside its limits. If more
than one error/alarm is present, the status bar slowly rotates though the various alarm states.

Description
Green Normal state - boiler is operating within its limits.
Yellow Warning error - When the controller detects an error.
Red
Alarm - Unresolved condition or error detected while the boiler is firing or
preparing to fire that results in the boiler shutting down and entering a lock-out
state. To change these error lockout periods, see Changing default error
lockout time periods on page 77.
For minor errors, the boiler will lock out for 5 minutes, and then attempt
to restart automatically.
For major errors, the boiler will lock out for 60 minutes after 3
unsuccessful ignition attempts, and then attempt to restart.
