After resetting (unit factory reset) and reconnecting to InstrumentConnect, the freezer will appear as a new connection
within the user's connected devices on InstrumentConnect. This is because a new security certificate will be established. The
freezer will be unable to re-connect to the original device under the “old” security certificate.
