Humidity and temp. step transformer controller 2.5A

The 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 4meter long cable.
