Issue
How to read the Setpoint potentiometer of a TSMN-90250-850 room sensor in an MNL-800.
Environment
MNL-800
TSMN-90250-850 room sensor
Cause
Need to scale the voltage inputs in the AI object in the MNL-800 application.
Resolution
Connect:
SP+ to the 5.1VDC source on the MNL-800
SETPT to the INx input on the MNL-800
COMMON to C on the MNL-800.
Might need to adjust the UI configuration in the MNL-800, here's starting point:
Add the SP to a UI on the MNL-800. In the AI object with Low Value = 0, Scaled Low value = 94.7 deg; High Value = 5 , Scaled High = 47.1 deg F.
