Energy Modes
Energy Mode One - This mode is automatic, and starts

the oven. In this mode, the main oven blowers will lower
to 1500 RPM, while the oven maintains temperature and
belt speed.
Energy Mode Two - The oven lowers its set point by 100°
F, and stops the belt. Anytime that the oven is more than
10 degrees over its set point, the burners will completely
shut off, allowing the oven to cool and the burners are on
minimum flow. The main blowers will continue to run at
1500 RPM in this mode. Placing any article on the input
belt will cause normal operation of the oven to resume, and
bring the set point back to its original level. The belt will
resume operation once both sides of the oven are within
5° F of the set point.
Energy Mode Three - The oven will turn off completely and
shut off the circulation blowers once the oven temperature
has dropped below 200° F. Placing any article on the input
belt will cause normal operation of the oven to resume, and
bring the set point back to its original level. The belt will
resume operation once both sides of the over are within
5° F of the set point.
Energy Mode Four - This is a complete oven shut down.
Placing anything on the belt will NOT return the oven to
Operation. The ON button on the main screen has to be
pressed to restart the oven.
