Heat Sensor
This unit is equipped with a Heat Sensor that automatically turns off the fan if a
certain temperature is reached from cooktop heat.
The fan will go up to high speed until the temperature comes back down to a
normal temperature level. Once the normal temperature has been reached, the
unit will return to the previous setting before the heat sensor was activated.
