The step transformer controller has the special characteristic that the ventilators make no noise hum at lower rotations. The step transformer controls the fan speed in a 6-step up/down manner according to the temperature. The temperature hysteresis (sensitivity) can be set using two knobs.
The controller comes as a finished part and is ready to use. This reliable fan controller comes complete with a sealed water resistant cover, plugs with flap-lids, and a low voltage sensor, making it perfect for humid rooms. The sensor comes with a 4-meter long cable and can be extended up to 50 meters.
