If the temperature dependency is implemented via a deterministic pseudo-random algorithm, then they are deterministic. If, on the other hand, the output is at least partially causally dependent on a source of environmental randomness, then, even though everything 'inside the box' is deterministic, the process as a whole may or may not be, depending on whether the source of environmental randomness is, and that is ultimately a question about fundamental reality.
