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 section
11
If you want to set a Pt100/1000 input for other purposes, you can
12
do this manually.
13
You can set the analog inputs via the "Setup, analog input" menu.

If you make the manual setting via Grundfos GO, you need to
16 enter the menu for the Pt100/1000 input under the "Settings"
menu.
