Mine does, but not quite what I remembered.

It specifies a maintaining minimum temp of 55F (13C?), however this is
when the house is unoccupied. Unoccupied is defined as being un-lived
in for over 60 days .(my previous had a similar sort of thing)

I missed the bit about this being unless you drain down the systems and
turn off the mains etc.
