The smart thermostats BGE offers allow only two overrides per day, iirc 30 or 60 min each. Not sure on that part, but the specific period isn't so much at issue as that somebody else has the privilege of deciding when I am allowed not to swelter.
(I saw some mention of a "smart switch" also installed under this program, which I assume is there to prevent "overriding" the meter by just yanking it off the wall and shorting the contacts.)
