CAUTION! Risk of material damage!
Modifying the settings for the differential pressure sensor can lead
to malfunctions. The factory settings are configured for the sup-
plied WILO differential pressure sensor.
• Default value: input In = 0-10 volts,
pressure value correction = ON
• When using the supplied Wilo differential pressure sensor,
these settings must not be changed!
Modifications are only needed if another differential pressure
sensor is used.
