Hi Jennifer,
Here is the manual for your model:
Toastmaster Bread Maker Models TBR15 and TBR15CAN
Instruction Manual and Recipes (click here)When you use the delay timer the machine will know when to turn on and off. In the manual you'll find the basic times that the bread takes. Just use caution not to use the delay start when using recipes with eggs or other perishable ingredients.
Happy Baking!
Betsy
