8.5. REPLACEMENT OF THE BATTERY BACKUP MODULE
The battery backup module has to be replaced in case of memory loss or as a
preventive measure after approximately three years usage. The nominal lifetime of
the accumulator is three years. The battery backup module is accessible after
opening the housing on the left-hand side in the lid. It is recommended to replace the
whole battery backup module which is plugged into the control module.
Before disconnecting the module from the socket, release the three snap-in lockings.
The control module has its basic settings after replacement.
