Penair Air Temperature Sensor

Hello. I do not have a Solar Water heater system. My pool guy states I need to replace my water temp sensor. I believe that Part #520272. There is a sensor hanging down from the bottom of the control cabinet. Could that be sensor Part #522101? If I have to replace one of them, minus well replace them both. Now, contacting Pentair, they said to use Part #520272 (same as for water temp) for the air temp sensor. Do you agree? Very confusing. Thank you for any comments.

Welcome to the forum.
They are the same part for air and water sensor.
