摘要

A ventilator for a stove includes a fan with a motor, and a microprocessor controller that regulates the speed of the fan motor. The controller has a first input from a wireless receiver with a remote control, and a second input from a rotatable local control knob with a rotary encoder. Signals received from the remote control and the rotary encoder indicate whether to increase or decrease the power supplied to the fan, and by how much.
