WOLF CT Hoods and DD Ventilation

ELECTRONIC CONTROL FOR COOKTOP WALL HOODS

Wolf ventilation hoods utilize a 6 button control panel with LED indicators, mounted along the right front edge of the unit. (See Figure 3-1)

The LIGHT button turns the halogen lights on and off, and allows the user to choose from three lighting levels: high, medium, and low.

The HIGH, MEDIUM, and LOW buttons control the operational speed of the remote or internal blower. An LED indicator below the button indicates the speed of blower operation.

To turn the blower off, depress the button over the illuminated LED.

The DELAY button activates the delay feature, which allows the blower to continue running at the selected speed for a programmed time period after the button is depressed.

When in Delay mode, both the Delay LED and the corresponding blower speed LED will be illuminated.

• If the blower is on high speed when the Delay mode is activated, it will continue to run at high speed for 5 minutes, then at low speed for 5 minutes before turning off.
• If the blower is on medium speed when the Delay mode is activated, it will continue to run at medium speed for 5 minutes, then at low speed for 5 minutes before turning off.
• If the blower is on low speed when the Delay mode is activated, it will continue to run at low speed for 5 minutes and then turn off.
• If the DELAY button is depressed when the blower is off, no action will take place.
• If the DELAY button is pressed when the unit is already in delay mode, the delay mode will be cancelled.

The FILTER button monitors the use of the hood. After 30 hours of use at medium speed, the Filter LED will illuminate, indicating the filters should be removed and cleaned. Depress the Filter button to reset the Filter clean LED.

LED Indicators

Figure 3-1 illustrates the controls and their corresponding LED indicators for Wall and Island Hoods.

HEAT SENTRY MODE

Heat Sentry Mode is always on standby and is activated when the exhaust temperature from the hood reaches 206°F (97°C). When this temperature is reached, the blower motor speed will automatically adjust to the next highest speed, or turn on if the blower motor was off. The LED of the corresponding blower speed will flash on and off to indicate Heat Sentry Mode.

Once in Heat Sentry Mode, the hood will continue to monitor exhaust temperatures every three minutes. If the exhaust temperature is at or exceeds 206°F (97°C), the blower speed will be increased to the next highest speed, and the corresponding LED will begin to flash. If, after three minutes, the exhaust temperature falls below 174°F (79°C), the blower speed will decrease to the next lowest speed. If the blower was off prior to Heat Sentry Mode, the unit will turn off when exiting Heat Sentry Mode.

When the blower speed returns to its original setting prior to Heat Sentry Mode activation, the corresponding LED will stop flashing and remain constant.

ELECTRONIC CONTROL FOR LOW PROFILE HOODS

The Wolf cooktop low-profile hood is operated using the touch control pads on the front face of the hood. (Figure 3-3)

LIGHTS: Touch the pad once to turn the lights ON, touch a second time to turn the lights ON to a brighter level, and touch a third time to turn the lights OFF.

0-1: Touch activates the blower motor at the first speed (icon is illuminated). Press the pad for about two seconds to turn the blower OFF.

2: Activates the blower at the second speed.

3: Activates the blower at the third speed.

4: Activates the blower at the fourth speed.

A: Touch the pad to set a TIMER which keeps the blower operating at the current speed for 10 minutes.

F - FILTER: After 30 hours of operation, the icon is illuminated to indicate that the grease filter(s) must be cleaned. After 120 hours, the icon flashes to indicate that the grease filter(s) must be cleaned and the charcoal filter replaced. To reset the hour counter, touch (F) while the icon is illuminated or flashing.
