Chapter 15 Memory function on power
failure
On power failure, settings and configurations are preserved in the controller in a so-called non-
volatile memory (EEPROM). All changes made to the settings and configuration is saved in
the memory, which means that the latest values are always stored. Measured values, as well as
other variables that change often, are not stored.
Values can be saved up to approximately 100 000 times in the non-volatile memory. Therefore,
changed values should not systematically and very often be sent to the controller via network
communication. Normal changes may still be sent via the network; for example if the operating
mode is changed a few times per day.
Disable autosave
There is a function to disable the automatic saving to EEPROM. We recommend to use this
function when huge amount of changes are sent to the unit via network communication.
Save now to EEPROM
This function saves all settings right now to the EEPROM. If autosave is disabled, it is highly
recommended to save all settings to the EEPROM after configuring the unit for all settings to
be kept after any type of power failure or restart of the unit.
Example
Activation of Bypass is not stored in the memory. Instead, the controller will return to the pre-
set operating mode after power failure. However, the set operating mode will be saved if
central control is being used (parameter 47).
