Humidity & temp. step transformer controller (2.5A)

The step trаnsformer controller have the special characteristic thаt the ventilators make no noise "hum" in the lower rotation.

The step trаnsformer 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.
This reliable fаn controller comes complete with a seаled 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.

Settings range:

• Temperature: 20C° - 30C°
