BEFORE YOU BEGIN PROGRAMMING

The readout must display "ENTER" before the computer will accept any programming.
If the readout displays any other word, turn the oven Off then back On before beginning any programming
sequence.
The Control allows for a 3 second delay between each button push, if a delay of longer than 3 seconds has
occurred, the programming sequence must be re-entered.
Once the programming code is entered, the readout will prompt for the program information. The sample
screens, below, will describe what each prompt means.

The convection fan has two programmable options. Fan On (Fan 1) runs
the convection fan continuously. Fan Off (Fan 0) leaves the fan off until
heat is called for by the control. In a convection oven, the fan must come
On whenever the heat comes On. The convection fan can not be turned Off
continuously.
"Tiered" programming is the ability to change the cooking temperature or
fan function during the cooking cycle. As an example, some products
require the fan to be Off for the first half of the cooking cycle then turn On
for the last half, Tier 1 would be programmed with the fan in the Off mode
then Tier 2 would be fan On. The Tier lamps located below the display
(labeled T1, T2, T3, T4) will illuminate to indicate which Tier is being
programmed or which Tier the program is in during the cooking cycle.
