Analog Inputs - Grundfos CRE Installation And Operating Instructions Manual

8.4.7 "Constant other value"
Pump variant
CME
CRE, CRIE, CRNE, CRKE, SPKE, MTRE
Any other value is kept constant.
Use this control mode if you want to control a value which is not
available in the "Control mode" menu. Connect a sensor measuring
the controlled value to one of the analog inputs of the pump. The
controlled value is shown in percentage of sensor range.
Factory setting
See the section on factory settings.

8.4.8 "Constant curve"
Pump variant
CME
CRE, CRIE, CRNE, CRKE, SPKE, MTRE
You can set the pump to operate according to a constant curve, like
an uncontrolled pump. See the figure below.
The desired speed can be set in % of maximum speed in the range
from 13 to 100 %.

8.5 "Analog inputs"

Available inputs depend on the functional module fitted in the pump:
"Constant other
value"
Function (terminal)

●
"Analog input 1, setup" (4)
"Analog input 2, setup" (7)
"Analog input 3, setup" (14)

If you want to set the analog input for a feedback sensor, we
recommend that you do this via the "Assisted pump setup" menu.
See the section on assisted pump setup.
If you want to set an analog input for other purposes, you can do
this manually.
You can set the analog inputs via the "Setup, analog input" menu.
See the section on setting up the analog input.
If you make the manual setting via Grundfos GO Remote, you need
to enter the menu for the analog input under the "Settings" menu.
