"Service reminder" function
The thermal module is fitted with a function that reminds the
user of the need to carry out planned maintenance on the ap-
pliance after a number of hours defined in the maintenance
plan.
When this maintenance activity is required, the following text
appears on the normal display:
"Maintenance required!"
This text will remain active until the technical support service
resets the internal meter after maintaining the appliance.
The user can check at any time how many hours miss from the
next planned maintenance activity by accessing the "Informa-
tion” menu
