NOTE 2 - Flow Rate Functions
Through the Flow Rate Functions it’s possible to check circulation
in different conditions. The DHW ow rate function can be used to
detect obstructions that reduce the ow rate value of the internal
boiler circuit (i.e. due to plate heat exchanger clogging). Thanks to
CH ow rate function it’s possible to perform the central heating
balancing.

PARAMETERS BACK-UP FOR PCB AND DISPLAY REPLACEMENT
This function enable the boiler to automatically store, each
2 hours, the parameters back-up in the display internal
ash memory. Thanks to this function during the PCB
replacement is possible restore the previous parameters
setting. Read the instructions manual for changing the Main
PCB, Display PCB or Display.
