Sens-A-Source The Sens-A-Source uses an integrated two-speed blower and heat sensor (standard on halogen light models only, not available on fluorescent models). It allows you to turn the blower to half-speed for even quieter operation. The heat sensor automatically increases (at 150 degrees F )blower speed for fire safety and grease liquefaction .

1. All Vent-A-Hood halogen light models are shipped standard with Sens-A-Source two-speed motor(s) (SS/1).
2. The heat sensor will change the two-speed blower motor from low speed to high speed if too much heat, steam, smoke, or a fire occurs.
3. The heat sensor will not turn the blower on if the blower switch is in the off position; only if the two-speed motor is turned to low speed.
4. Once the heat sensor cools down, the blower will return to low speed.
5. If the blower automatically increases to high speed, it may be turned off manually.
