The Emerson DLT’s that I’m used to seeing are pretty much a snap disc thermostat. The controller is looking for an opened or closed signal not a value like a thermistor would provide.
Is there a way to display what the control is reading for discharge line temperature?

There is a thermistor for discharge temp and a sealed switch for head pressure. Also this one looked like it had another thermistor for fan cycling.
Got a model number?
Sounds like an FFAP base. You can adjust its parameters. And you can ohm it out and compare it to the chart. But I’m pretty sure there isn’t a way to display that sensor’s reading. If there is, I’m sure you’ll figure it out.

Link to Copeland AE bulletin. Only gives alarm code and thermister temperature resistance values.
If you had a compressor with the Core-sense motor protector, you could have temperature read-out.
Thanks guys. It was 110° in the mechanical room and I didn't see it speed reading the manual. I'll give it a closer look later but sounds like they left that feature out.
Thats why I carry 2 Supco Digital thermometers in my tool box.I am interested in DLT.
