This semi-variable minimum speed controller is a temperature dependent fan controller for ventilated rooms designed for one or more exhaust fans. The fan controller keeps the room temperature constant and prevents it from falling below the set minimum speed. It is easy to use, the desired temperature and the minimum speed is set by two buttons. Depending on the temperature and power of the fan, the controller varies and switches to full power when overloaded. The sensor comes with a 2 meter cable and is plug-able.
