Do I need to adjust my Navien NCB-180E from summer to winter?

The "cold water inlet temperature" certainly changes, but do I have to change the setting for it? Seems silly - why isn't the Navien sensing the temperature??

I now see that cold water inlet temperature is just an informational display. Nevermind...
