The constant control of the fan speed in the grow tent
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 to the temperature. Temperature as Hysteresis (sensitivity) can be set on two knob's. On a internal hardware setting (Jumper) you can choose if the minimum speed is 0 "zero" off position or if the fan should keep working in the lowest step to prevent odors escaping.
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.
