G-Systems Humidity & Temp. step transformer controller have the special characteristic that the ventilators make no noise "hum" in the lower rotation. The step transformer control the fan speed from self 6-step up & down according the humidity and temperature. Temperature and hysteresis (sensitivity) can be set on two knob's as well humidity and humidity-hysteresis on the other 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 m long cable.
