Diagnostics
Boiler is equipped with modern system for autodiagnostics. In case of boiler error, display flickers
together with the sign of error and number indicating error code.
There are errors, that cause permanent blockage (marked by „
A “ letter): to get boiler back to normal
operation, press RESET button for 1 second or use RESET on remote time controller (additional), if
it is installed; if boiler does not come to operation, it is necessary to remove the fault. Errors (marked
by „
F “ letter) cause often blockages, that are automatically removed, immediately after the value gets
back into the interval of normal boiler operation.
