I wouldn't trust such controller anyway. 15 degrees difference and it
(allegedly) gives you silent data corruption? What if you have a particularly
hot day, and/or the AC is out for a few hours.
There is a lot of better failure modes than this (honestly reported read or
CRC errors for a start, or heck, even complete lock-up of the controller would
be more preferrable).
