    Yes, we do carry the three wire dampers but they all aren't on the website yet. Please feel free to email us with your specific requirements.

    Thanks,

    Martin

    If you look at the bottom picture, you will see a standard damper with a Servo connected to it. Maybe this will give you an idea how to connect them up.

    The servos are usually used in RC boats and airplanes. Most are small, but there are also some large ones. They have geared motors that generally can rotate up to 180 degrees with usually 255 descrete positions. They are controlled via a servo controller, which is controlled via the serial port. A lot would depend on how your current dampers work and how hard they are to operate. Below are some simple setups I've made for fun using the servos.

    Thank you for the advice. Servos are not something I am familiar with. Can someone please direct me to a good info source on this subject. Thank you for your help.

    I don't know about the unity system, but typical lower-cost electrically-controlled dampers are controlled with a ON/OFF discrete. It may be possible to modulate the flow over time, but you will not be able to achieve a steady-state 30% open unless you go to something like zoomkat suggested.

    Damper modulation

    Guys, does anyone know how to modulate dampers so that they can go from 0-100%? The only thing I've seen are dampers that can be either opened or closed. My current system, the Unity System Home Manager can go from 0-100% but I have yet to find any other system that can do this. Thoughts?
