The pressure suppression function eliminates this effect by activating a larger low flow cutoff
level for a short period of time. The pressure suppression is activated when the flow falls below
the standard low flow cutoff level for the first time. For a programmable period of time, (can be
programmed in menu C1.3.2), the pressure suppression threshold is added to the standard low
flow threshold (can be set in menu C1.3.3).
The optimal setting values for pressure suppression depend on the current operating conditions
and can thus only be determined on-site through testing.
