7.7.3 Temperature influence
Description of function, see section 6.6 Temperature
influence.
Note: If the pump is controlled via bus or in control
mode AUTO, temperature influence cannot be set by
means of the R100.
The temperature influence function can be activated
in this display when the control mode is proportional
pressure or constant pressure, see section
7.7.1 Control mode.
In the case of temperature influence, the pump must
be installed in the flow pipe. It is possible to choose
between maximum temperatures of 50°C and 80°C.
When the temperature influence is active, a small
thermometer is shown in the display "Setpoint" in
menu OPERATION, see section 7.5.1 Setpoint.
7.7.4 Buttons on pump
To prevent unauthorized persons from operating the
pump, the function of the buttons
be deactivated in this display. The buttons can be re-
activated only by means of the R100.
The buttons can be set to:
• Active,
• Not active.
7.7.5 Pump number
A number from 1 up to and including 64 can be allo-
cated to a pump or can be changed so that the R100,
Pump Management System 2000 or other systems
can distinguish between two or more pumps.
7.8 Priority of settings
The external forced-control signals will influence the
settings available on the pump control panel and via
the R100. However, the pump can always be set to
max. curve duty or to stop by means of the pump
control panel or via the R100.
If two or more functions are activated at the same
time, the pump will operate according to the setting
with the highest priority.
The priority of the settings is as shown in the follow-
ing tables:
Without expansion module:
Priority
1
2
3
4
5
Example: If, via an external signal, the pump has
been forced to stop, the pump control panel or the
R100 can only set the pump to max. curve.

As illustrated in the table, the pump does not react
on external signals (max. curve and min. curve)
when the pump is controlled via bus.
If the pump is to react on external signals (max.
kurve and min. curve), the system must be config-
ured for that function.
For further details, please contact GRUNDFOS.
