This G-tools ventilator has a build in fan speed controller. Ideal for use in rooms with big temperature differences (light on/light off).
These state-of-the-art inline ventilators are protected by a thermal switch to prevent overheating. They are equiped with a temperature sensor on a 4 meters cable. With two dials you set the desired temperature and the minimum fan running speed. When the temperature in the room exceeds the set temperature, the fan gradually starts running at full speed. As soon as the temperature drops below the set temperature, the fan will fall back to the set minimum speed. The controller works with a so called “hysteresis” of 2 degrees. This means that the fan will build up it’s running speed to full power during a temperature rise of two degrees.
