3 temp sensor 2 A/C

[Blue-JAY]

2021 Pinnacle 36swss. We have two temp sensors in the main area next to the key drop. However we have only two A/C units. Are these unit wired for three A/C even though only two were installed?
We have a faulty sensor in the bedroom and until I can order a new one I was thinking I could just swap the unused sensor for the bad one.

Specs show optional 3rd a/c so it's probably prewired.
