Yes, but Hoover for one uses a temperature probe cast into the pan which is accommodated into a small cast aluminum hole in the temperature control (so there are 3 holes---FFF on a Hoover temperature controller, but only two--and a probe--FMF on a Presto/Farber/Sunbeam). Not compatible and you'd burn out the pan if you tried to use it (nothing for the pan to tell the controller to shut off).
