humidity & temperature speed control for rooms with air flow in and out. The controller keeps the room humidity & temperature constant and under negative pressure to prevent odors from escaping.It can be easily controlled, adjusting the required humidity, temperature, min. speed and negative pressure in your room on four rotary knobs. Three low-shining LED lights indicate the control status and on-position. This fan controller can also be used as an air out only controller on two fans, if there is a natural way of air in. The controller comes as a finished part and is ready to use. This reliable fan controller comes complete with a sealed water resistant cover, plug with flap-lid and a low voltage sensor making it perfect for damp rooms. The sensor is supplied with a 4-meter long cable.
