Wall Oven Series Electronic Control System SECTION 3 ELECTRONIC CONTROL SYSTEM 3-1
Electronic Control System Wall Oven Series ELECTRONIC CONTROL TERMINOLOGY & COMPONENT DESCRIPTIONS All Wolf wall ovens utilize an electronic control system. The electronic control system monitors, regulates and controls a variety of functions. The control system also displays error codes to identify possible problems with the unit. The table below defines some of the basic electronic control system terminology and describes some of the electronic system components.
Wall Oven Series Electronic Control System UNIQUE ELECTRONIC CONTROL INPUT OPERATIONS The following few pages illustrate electronic control input operations that you would not expect a customer to perform everyday. The input operations described are: Field Option Mode, Sabbath Mode, Delayed Start Mode, Probe Mode and Self-Clean Mode.
Wall Oven Series Electronic Control System Sabbath Feature Sabbath Feature was incorporated into the electronic control system for the observance of certain religious holidays. Once Sabbath Mode has been entered, all of the oven functions have been disabled except the OFF key. To initiate Sabbath feature, the oven must be OFF. Press UPPER or LOWER OVEN ON key for a double oven or OVEN ON key for a single oven. (See Figure 3-3). Turn on the interior oven lights by pressing the OVEN LIGHT ON key (Optional).
Wall Oven Series Electronic Control System Time Cook Feature Time Cook Feature controls the automatic timing of the oven(s) ON and OFF function by setting the cooking time to start immediately and turn off when the desired cooking is complete. To accomplish time cook, the time of day clock is used and therefore the correct time must be displayed prior to programming. To initiate Time Cook, the oven must be OFF. First press the Oven ON key. (See Figure 3-7).
Wall Oven Series Electronic Control System Delayed Start Feature This feature controls the automatic timing of the oven(s) ON and OFF function by setting the cooking mode to start later in the day and turn off when the cooking is complete. It can also be set to turn off at a preset time. To accomplish delayed start and/or stop, the time of day clock is used and therefore the correct time must be displayed prior to programming.
Wall Oven Series Electronic Control System Temperature Probe Feature The Temperature Probe Feature is used to measure internal temperatures of the food being cooked. It is an accurate way to achieve the perfect doneness regardless of the type, cut or weight of food. When using the Temperature Probe Mode, program the recommended internal carving temperature, as found in the Use and Care Information Guide. (See Figure 3-16).
Wall Oven Series Electronic Control System Self-Clean Mode In Self-Clean Mode, the oven is heated in graduated stages to a preset high temperature. The cycling of the bake and broil elements in Stage One last for the first twelve minutes. In Stage Two, the bake element cycles for 0 - 12 seconds and the broil element cycles for 12 - 60 seconds. The cycling of the elements in Stage Two continues until the high preset temperature of 850°F is obtained.
Wall Oven Series Electronic Control System ELECTRONIC CONTROL INPUT OPERATIONS The following few pages illustrate electronic control input operations that you might expect a customer to perform everyday. The input operations described are: Bake, Convection, Convection Bake, Broil, Convection Broil, Roast, Convection Roast and Bake Stone Mode. Bake Mode In Bake Mode both the hidden bake element and the broil element are used to heat the air and cycle to maintain temperature.
Wall Oven Series Electronic Control System Convection Mode The Convection Mode uses dual convection fans, each with heating elements mounted on the back wall of the oven cavity. The convection fans move air sequential, throughout the entire oven cavity creating uniform air movement. This air movement makes it possible to cook on all six levels of the cooking racks simultaneously. The heating elements and convection fans are cycled sequentially (on and off), resulting in even browning.
Wall Oven Series Electronic Control System Convection Bake Mode Convection Bake Mode combines heat from two convection heating elements with some heat from the hidden bake element. The two convection fans and convection elements operate sequentially (on and off), to circulate the heat within the oven cavity. The added heat from the hidden bake element make this an ideal cooking mode for pie baking.
Wall Oven Series Electronic Control System Broil Mode In Broil Mode the top broil element is used to conduct an intense radiant heat which browns one side of the food being cooked. Food cooked in any of the Broil Modes must be turned to finish cooking and browning the other side. There are three Broil Level temperatures that can be used in this mode, Hi Broil, Medium Broil and Lo Broil. NOTE: Preheat is never used in Broil Mode. NOTE: The oven door MUST be closed during this mode.
Wall Oven Series Electronic Control System Convection Broil Mode Convection Broil Mode uses intense radiant heat from the top broil element. The convection fans also operate continuously to maintain air movement. Convection Broil Mode shortens broiling times for thicker cuts of meat. The intense radiant heat browns and sears the surface of the meat, while the convection fans keep the interior of the meat moist. NOTE: Preheat is never used in Convection Broil Mode.
Wall Oven Series Electronic Control System Roast Mode In Roast Mode both the hidden bake element and the broil element are cycled to maintain the desired temperature. The hidden bake element operates 75 percent of the time and the broil element operates 25 percent of the time. This mode is especially designed for roasting tender cuts of meat that need to be covered. NOTE: The oven should always be preheated in this mode. The oven will chime after the oven reaches preheat temperature.
Wall Oven Series Electronic Control System Convection Roast Mode In Convection Roast Mode the dual convection fans with each convection element operate sequentially (on and off), along with the cycling of the top broil element. The convection elements are on 46 percent of the time and the broil element is on 16 percent of the time. The convection fans are on 100 percent of the time. This mode intensifies the convective and radiant heating.
Wall Oven Series Electronic Control System Bake Stone Mode In the Bake Stone Mode a specially designed oven rack and heating element are used along with a ceramic stone. Mounted directly underneath the ceramic bake stone is a heating element. This bake stone element along with the convection fans and the broil element help produce a hot enough environment necessary to cook on the ceramic stone.
Wall Oven Series Electronic Control System Dehydration Feature This feature allows for slowly drying out food for preservation and other cooking uses. This requires an optional accessory package. To initiate the Dehydration Feature, the oven must be OFF. First press the Oven ON key. (See Figure 3-55). For Double Ovens press the Upper Oven ON key or the Lower Oven ON key. Now, press and hold the CONVECTION key for 3 seconds. A preset temperature of 160°F is shown in the display.
Wall Oven Series Electronic Control System Proof Feature How PROOF feature works: A combination of Broil, Convection and Bake elements are used to heat and balance the air to maintain temperature. This feature is ideal for proofing bread dough. The oven does not allow the temperature to be set above 110°F (43.3°C). If the oven temperature is above 130°F(55°C), “HOT” will be indicated on the control panel.
Wall Oven Series Electronic Control System Panel Lock When the electronic control panel is visible, the oven is operational. When initiating the panel lock feature all modes and key pads will be non functional except oven OFF touch pad and PANEL LOCK touch pad. This keeps it child safe and prevents oven from accidentally being turned on. Setting Panel Lock: • Press and hold Panel Lock touch pad for 3 seconds. Two beeps will be heard and oven display will show PANEL LOCKED for 5 seconds.
Wall Oven Series Electronic Control System INITIATING DIAGNOSTIC MODE UPPER OVEN To initiate Diagnostic Mode for the Upper Oven, the oven must be OFF. Then press and hold the TEMPERATURE key and the 0 “ZERO” key for 3 seconds, then release both keys. (See Figure 3-65). NOTE: Diagnostic Mode will end 2 minutes after last key stroke or when the CLEAR key is pressed. LOWER OVEN To initiate Diagnostic Mode for the Lower Oven, the oven must be OFF.
Wall Oven Series Electronic Control System POSSIBLE ERROR INDICATORS The last occurring error will be shown in the text area of the Display board. Pressing the ENTER key will cycle through the last occurring seven errors for the oven. The Double Wall Oven stores a total of 14 errors, seven for the upper oven and seven for the lower oven.
