GSE Digital Controller for Temperatures, Negative Pressure and Minimum Speed of Fans, 2 x 5 A

Product detailed description

The controller is designed to maintain a stable climate in growing rooms or facilities with intensive ventilation according to the preset optimum temperature, negative pressure and minimum fan speed. The device also regulates the speed of the intake and extraction fans to maintain constant negative pressure in the room, making odour filtration and room ventilation more effective. 

The controller can operate one or two fans, either for intake and extraction or for air extraction only. We recommend using the controller with two extraction fans only if an air supply is ensured, either naturally or by another regulated fan. 

The device’s protective cover is rated IP54, making it resistant to dust and splashing water, which is particularly suitable for humid growing-room environments. 

Setting up the controller is simple and requires only three rotary knobs. One sets the ideal temperature, the second the minimum extraction fan speed and the third the intake negative pressure.

When the room is at the optimum temperature, the extraction fan remains at the set minimum speed and the intake is switched off completely. As soon as the temperature reaches 2 °C below the ideal value, the extraction fan gradually increases its speed up to full power. At the same time, the intake fan switches on and gradually increases its speed up to the set maximum negative pressure. The temperature begins to return to the preset value and the fans gradually reduce their speed. 

The controller is supplied with a temperature sensor already connected via a four-metre cable.
