The diverting valve switches from the DHW position to the Heating position, and vice
versa, in 3 phases: The start phase (phase 1), where the valve is slowly and powerfully
started, the adjusting phase (phase 2), which should cover most of the valve’s travel,
and the stop phase (phase 3), where the valve is slowly driven against its mechanical
stop.
This parameter is used to set the number of steps for the respective phase.

This parameter is used to set the time for a step pulse in the respective phase. Note
that a full step consists of 8 partial steps. Thus, for a full step in Full-step mode, one
pulse is required, for a full step in Eighth-step mode, 8 pulses (8 times the amount of
time).
