Comma 2 Battery Drain - How To Disable Comma When Car Is Off?

How do I disable Comma 2 from draining the battery while car is off!

Everything was fine till I installed Comma 2 and now if I don't drive the car for 2 days the battery is just dead. Whether I drive 30 minutes or 1 hour, it doesn't matter. Battery is dead after Comma 2 connected the next day.
