This button is used to send the
settings made at the "mode"
rotary switch and the "set-
point" knob to the corre-
sponding pump. The settings
are only accepted if no com-
mands have been sent to the
corresponding pump via the
RS 485 bus (if the pump
was switched off, it will
now be switched on).
The address of the corre-
sponding interface converter
is set at this DIP switch block.
The baud rate of the RS 485
interface is set at this DIP
switch block.
At these DIP switches, a termi-
nation resistance can be con-
nected to the RS 485 interface
for each cable.

The analogue input "0-10V" is
released for each pump with
this switch:
• 0-10V: Release analogue
input "0-10V"
• disable: analogue input
"0-10V" blocked
The signal at the analogue
input "0-10V" specifies the
setpoint for the mode set with
the "mode" rotary switch:
• Δp-c: 0V = H
, 10V = H
min
• Δp-v: 0V = H
, 10V = H
min
• n-c: 0V = min. speed,
10V = max. speed
• The signal at the analogue
input "0-10V" overrides the
value set at the "setpoint"
knob and the setpoint trans-
mitted via the RS 485 bus.
