Automatic Heat Sensor
What is a hood 'Heat Sensor'?
Thermal Trigger Activation
Luxury liners (e.g., Vent-A-Hood) include a thermistor that automatically turns the fan to "High" if it detects temperatures over 150°F. This protects the wood shroud and electronic components from thermal damage.
Safety hardware that automatically triggers high-speed exhaust if temperatures below the hood reach a critical threshold.
