10. DIAGNOSTICS AND ERRORS.
10.1 Diagnostics.
The CAR
V2
remote control continually controls the
functioning status of the boiler and signals any anomalies,
stating the corresponding error code on the display.
The error codes have meaning depending on the boiler to
which the CAR
V2
remote control is connected. Therefore,
refer tot he boiler instruction book for a complete list of
error codes and their relative meaning.
In the case of a fault that cannot be reset, contact a qualified
technician (e.g. the After-Sales Technical Assistance
Service).
“ERR>XX” appears on the display in the event of an error,
where XX stands for the number that identifies the error
code as well as the flashing symbol.
As well as the error codes referring to the functioning state
of the boiler, the CAR
V2
remote control also checks its own
functioning state, indicating any malfunctions.
