Programming
The Batch Toaster is pre-programmed with standard
menu programs at the factory. Perform the following
steps ONLY if you wish to change a program’s settings.
IMPORTANT

an existing program. Do not overwrite a program that
you wish to keep!

The toaster regulates heat through three relays.
Each relay controls four of the twelve heating
