That is why you may need more than one stat wired in parallel.
Just like a frost stat is wired in parallel with the room stat.

Have you never heard of programmable stats - which can be programmed to work
at different temperatures at different times *and* act as frost stats in
their OFF state? No need for any parallel wiring if you use one of these.

And it is *never* appropriate to wire in stats in parallel - thus
controlling the *same* thing - as a substitute for controlling *different*
things, as in zones.
