7.5 Menu OPERATION

When the communication between the R100 and the
pump has been established, menu OPERATION ap-
pears in the display.
7.5.1 Setpoint
This display depends on the control mode selected
in the display "Control mode" in menu INSTALLA-
TION.
If the pump is forced-controlled via external signals,
the number of possible settings will be reduced, see
section 7.8 Priority of settings. Attempts to change
the settings will result in an indication in the display
saying that the pump is forced-controlled and
changes therefore cannot be made.
This display will appear when the pump is in AUTO
mode.
Set the desired setpoint by pressing the buttons "+"
and "–" on the R100 (not possible when the pump
has been set to AUTO).
Furthermore, it is possible to select one of the follow-
ing operating modes:
• Stop,
• Min. (min. curve),
• Max. (max. curve).
The display is different if proportional pressure, con-
stant pressure or constant curve has been selected.
The actual duty point of the pump is indicated by a
square in the Q/H field. No indication at low flow.
7.5.2 Operating mode
Select one of the following operating modes:
• Stop,
• Min. (min. curve),
• Normal (AUTO, proportional pressure, constant
pressure or constant curve),
• Max. (max. curve).
7.5.3 Fault Indications
If the pump is faulty, the cause will appear in this dis-
play.
Possible causes:
• Pump blocked,
• Internal fault,
• Undervoltage,
• Module fault,
• Fault in module communication.
The fault indication can be reset in this display. If the
fault has not disappeared when resetting is at-
tempted, the fault indication will reappear in the dis-
play when communicating with the pump.
7.5.4 Alarm log
The alarm code with text appears in this display. The
display will also show the number of minutes the
pump has been connected to the electricity supply
after the fault occurred.
The last five fault indications will appear in the alarm
log.
