If you want to set the Pt100/1000 input for a feedback sensor, we
10
recommend that you do this via the "Assisted pump setup" menu.
See the section on assisted pump setup.
11
If you want to set a Pt100/1000 input for other purposes, you can do
12
this manually.
13
You can set the analog inputs via the "Setup, analog input" menu.
See the section on setting up the analog input.
14
If you make the manual setting via Grundfos GO Remote, you need
15
to enter the menu for the Pt100/1000 input under the "Settings"
16
menu.

The Pt100/1000 inputs can be set to these functions:
• "Not active"
• "Feedback sensor" The sensor is used for the selected control
mode.
• "Ext. setpoint infl." See the section on the external setpoint
function.
• "Other function".
Measured parameter
Select one of the parameters listed below, i.e. the parameter to be
measured in the system by the PT100/1000 sensor connected to
the actual PT100/1000 input. See the figure below.
