Will Curt TriFlex Brake Controller Drain Battery Over Time

Question:

Does the 12 volt wire remain energized all the time or only when the tow vehicle is running? In other words, is there a possibility that this could drain the vehicle’s energy if something is left on? Thanks

The 12 volt power wire that runs to the Curt Triflex part # C24VV is hot all the time but when the controller isn't in use it goes into a sleep mode that prevents the battery from draining when not used for a while.
