14.4 Changing the storage battery
A CR2032 battery is located in the control unit. This battery enables the control unit to save certain
data - e.g. time, date, heating times etc. even during a power failure, or when the mains power supply
is disconnected.
If the battery is flat, the control unit will continue to function normally. However, in the event of a power
failure, the above-mentioned data will be lost. These data must then be saved afresh.
