The folllowing table contains all codes that can show on the BC10 display. To show the current display code and/or

-key repeatedly. There are 3 main code groups:
Operating codes - this code gives the status of the boiler.
No action is necessary.
Locking faults - the boiler resumes normal operation
when the fault has cleared.
Blocking faults - the boiler is locked and will only restart
after a manual reset. The pump will operate continuously
for frost protection.
If a blinking code is displayed together with other codes, all displayed codes will blink.
A locking code will always show on the first screen of the BC10.
