Is made to keep the temperature in any space under control. With the DV11-TII you can determine how warm it will become in the space. You set the desired temperature, and connect the suction device or extractor to the DV11-TII. You then set the minimum and maximum speed of your motor so it never runs too quickly or slowly. You can arrange this for 2 motors
The DV11-TII will then ensure that the temperature is maintained. The DV11-TII is protected by a 6 Amp thermal fuse.The thermal fuse ensures that the DV11-TII switches off with a short-circuit or overloading. The advantage of the thermal fuse is that when the problem has been fixed you only need to press the "reset"button and the DV11-TII starts working again.
The DV11-TII works on 230V.
