Thermador PH42GS Off, Fan Speed, Auto only on 27 models, Delay shut off, Clean Filter Reminder

Off

Pressing the button once turns ventilator off and resets the control.

Fan Speed

Pressing the button once, from an “off” state, turns the ventilator on low. Each successive press of the button increases the fan speed until high speed is reached, then the fan cycles back to the low speed.

The LEDs above this button indicate the current fan speed. When the fan is on, the corresponding LED is illuminated.

1 — Low

2 — Medium

3 — High

Auto (only on 27” models)

When in Auto mode, the hood automatically turns the blower on, depending on the amount of heat the control senses. It automatically adjusts every 5 minutes. If the control does not sense a high level of heat, it will turn the blower off.

Delay (shut off)

If the blower is off when the Delay button is pressed, the blower will turn on to the HIGH speed setting for 10 minutes. At the end of the cycle the blower will turn off.

If the blower is on when the Delay button is pressed, the blower runs for 10 minutes at the current speed then turns off.

During the 10 minute timed period, the LED above the Delay button is illuminated.

To interrupt a timed period, press Fan Speed or OFF button.

Clean Filter Reminder

After 40 hours of operation, the LED above the filter button will illuminate indicating that the filters need to be cleaned. When this indicator illuminates, clean the filters as instructed on page 6. After cleaning, press this button for 3 seconds to reset the 40-hour period and turn the LED off.

Light On/Dim/Off

This button controls the halogen lighting. The first press turns the lights on. A second press dims the lights. A third press turns the lights off.

Heat Lamp (only on 27” models)

The buttons marked “L” and “R” independently control the left and right infrared heating lamps, turning the lights on or off.

Heat Sensor Protection

Over Temperature Condition

The high temperature sensor protects the hood from high temperatures which may damage components. The control is set to activate at 161°F (72°C) and reset at 140°F (60°C). When activated, the blower will turn on low and the corresponding LED will blink, indicating an over- temperature condition.

While the high temperature sensor is activated, the blower speed can be manually changed or turned off. If the blower is turned off, the corresponding LED will blink. Light controls will remain operational. When the control sensor reaches 140°F (60°C), a reset will occur. During reset, the control will revert back to the operational state prior to the high temperature condition.

High Temperature Fault Condition

If in the uncommon occurrence the Heat Sensor Protection becomes damaged, the three fan speed indicator LEDs will start blinking. All of the controls will continue to be operational except for the indicator LEDs. To reach a service representative, see the contact information at the back page of the manual.
