* The switching time of the parameter SEQ CHANGE (Sequence change) can be adjusted up to 250 h only if the controller is used for controlling
two boilers equipped with a single-stage burner each.
If the controller is used for controlling a boiler with a two-stage burner, the parameter SEQ CHANGE must be left at “0 h”.
It must be left also at “0 h” if the controller is used for controlling two boilers, of which one, for instance, has a better efficiency and, the second
one, is used only when the first one is out of order or is not capable to supply, alone, the total heat necessary for the heating system.
