You can take control of a construct by voice or mental commands. The construct must succeed on a Wisdom saving throw to resist the spell, and it has advantage on the saving throw if its CR equals or exceeds your level in the class used to cast this spell. Once a command is given, the construct does everything it can to complete the command. Giving a new command takes an action.

Constructs will risk harm, even go into combat, on your orders but will not self-destruct, and giving such an order ends the spell.
