The lab answers the installer's questions the unattended way

The installer asks where a human must choose, and this bed has no human — so
every choice arrives as a flag, and a required choice with no flag is the
installer refusing, which is the behaviour rather than a lab problem.

Both choices have one option today, so the flags are redundant on purpose: the
day a second filter exists this bed keeps working instead of refusing, and
choosing becomes a thing it visibly does.
