Default Automatic probably

Most TTs come with two tanks and a switchover valve. Look at it and it will be apparent if you have it. It uses the tank that is selected until that tank runs out and then the indicator turns red and you are on the other tank. You an disconnect the tank that is not being used and take it to refill.
