Min. Curve Duty 7.2.4; Constant Curve Duty; Temperature Influence - Grundfos UPE 2000 Series Installation And Operating Instructions Manual

7.5.3 Head and flow
Very low flows cannot be registered, and the R100
will show "< " in front of the lowest possible value of
the pump in question.
7.5.4 Speed
The actual pump speed.
7.5.5 Liquid temperature
The actual temperature of the pumped liquid.
Because of the physical position of the sensor,
deviations in the temperature measuring may occur,
e.g. at high liquid temperatures and/or low ambient
temperatures.
7.5.6 power input and power consumption
Actual power input and power consumption of the
pump.
The value of power consumption is an accumulated
value and cannot be set to zero.
7.5.7 Operating hours
Operating hours of the pump.
The value of operating hours is an accumulated
value and cannot be set to zero.
7.6 Menu INSTALLATION
In this menu, the settings are chosen that should be
considered when installing the pump.
7.6.1 Control mode
Description of function, see section 6.2 Control
modes or section 6.5 Constant curve duty.
Select one of the following control modes:
• Prop. pressure (proportional pressure),
• Const. pressure (constant pressure),
• Const. curve (constant curve).
Setting of setpoint or curve is carried out in display
7.4.1 Setpoint in menu OPERATION.
7.6.2 Min. curve
Description of function, see section 6.4 Max. or min.
curve duty.
In this display, it is possible to choose between two
min. curves. The curve is used when the operating
mode "min. curve" is selected.

7.6.3 Temperature influence

Description of function, see section 6.6 Temperature
influence.
.
The temperature influence function can be activated
in this display.
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.
The temperature influence function will be active
only in constant or proportional-pressure control
mode.
When the temperature influence is active, a small
thermometer is shown in the display "Setpoint" in
menu OPERATION, see 7.4.1 Setpoint.
Note: If the pump is controlled via bus, temperature
influence cannot be set by means of the R100.
