7. Setting the pump
All control of the twin-head pump is carried out by
the master pump except when the pump is running
single-pump operation.
The slave pump will not respond to commands
(unless when in single-pump operation) from the
control panel, the R100 nor from external signal
transmitters but only to commands from the master
pump. All setting and reading of data must therefore
be done via the master pump.
The green slave pump indicator light will flash on and
off 20 times per minute to indicate correct communi-
cation between master and slave pump.
For the setting of the pump, use:
• Control panel.
• R100 remote control.
• Bus communication (not described in detail in
these instructions. Contact Grundfos).

vidual operating units and in which section the func-

The control panel, fig. 13, incorporates the following:
• Buttons, "+" and "-", for setting.
