I don't know how old your controller is but Hunter claims all their controllers have a non-volatile memory. Which means the controller retains the programming forever even without power. I'm not even sure when Hunter incorporated this feature.
Try taking out the back up battery and unplug the controller for a couple of minutes. See if that resets your programming back to where it was.
