SMOOTH SET BACK (SSR) default is OFF. When en-
abled, smooth set back begins recovery up to 2 hours be-
fore the programmed time so that the programmed tem-
perature is reached at the corresponding programmed

based heating or cooling. With Smooth Set Back disabled,
the control will start a recovery at the programmed time.
