4�3 RESET OPERATIONS AND MANUAL DEFROSTING
There are several possible reasons why the appliance may have error status and therefore its operation arrested; such an error situa-
tion does not necessarily correspond to damage or malfunction on the part of the appliance. The cause that has generated the error
may be temporary: for example, presence of air in the gas supply line or temporary power failure.
The appliance can be reset with controller menu 2, the Comfort Control Panel (if present) or the DDC (if present). In these two latter
cases, refer to their documentation.
