The EC-fan (electronically commutated motors) have a diameter of 125mm (soon available as 160mm and 200mm), it is a very power full fan with 950m3/h at 0[Pa]. The EC fan have the characteristic that he makes no hum on the low rotation and fulfill the required efficiency law by 2018. A built in LCD display with keyboard and power led allows a very easy setting and reading of all the information's given by the fan such as actual set speed, temperature, humidity day/night and rounds per minute of the motor. A built in light sensor in the probe recognize day/night modes. The Ventilator comes with 1.5m power cable and 4m sensors cable, it is ready to use. You can program 14 individual settings with only three buttons:

-Temperature day
-Temperature hysteresis day
-Humidity day
-Humidity hysteresis day
-Minimum speed day
-Maximum speed day
-Temperature night
-Temperature hysteresis night
-Humidity night
-Humidity hysteresis night
-Minimum speed night
-Maximum speed night
-Switch sensor level
-Switch over time day/night

LCD display:
-Graphic and digital display of speed rpm constant
-Temperature display constant
-Humidity display constant
-Set point selectable not constant, over input keys
