This may help, here is the link for single voltage. Thanks for correction Bill. US Motors has much info on their site, I searched
model number with no results though.
"OVER TEMP PROT 2" on the nameplate may be a clue.
This looks like a single voltage 4 lead motor.
The connection diagram that is not readable in your picture probably says something like:
"Single phase Motor Lead Connections
Connected for Counter - Clockwise Rotation
To Reverse Rotation Interchange Leads $ and %"
Note: "Volts 208/230" on the nameplate refers to the voltage tolerance range, not dual voltages.

I would agree with you bill on the "Motor Protection 2" and that's why I wanted us to see the nameplate.
helloman22; Use an ohm meter and measure across those two leads.
While you're at it make sure they are not common with any of the big yellow leads at the same time.
Let us know what you get for resistance between those two white leads.
I'd expect for an RTD you'd see something around 110ohms or 1,100ohms. If instead it's a thermistor I'd expect something over 10,000ohms but under 100,000.
