GSE Step transformer 2.5A - teplota/hystereze pro 2 ventilátory

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 temperature. Temperature as Hysteresis (sensitivity) can be set on two knob's. The intake fan runs 1step behind the exhaust fan to prevent odour from escaping.

Sample: Exhaust fan runs on step1, intake fan runs on step0 (stop), when the exhaust fan switch to step2 the intake fan switch to step1 etc... until the exhaust fan reach the max. step6 the intake fan will run on step5.

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 and can be extended up to 8meters.
