    this system will not work with a three speed motor

    there are damper controls that will work and the condenser isnt going to be the issue here it is going to be the blower

    what signal does the v drive send to the harmony??


    harmony varies voltage on the ds terminal to control blower speed i did not think it recieved any signal......

    was just trying to be simple

    with out ds the board will just keep locking out on fault codes. From my understanding since it has been tried and proven it will not work


    harmont1 i have done with three speed and also single stage and a lot of thought but harmony3 needs to be set up to control ramping of the blower and if it isnt getting the ramping Or cfm count from the controler it will pick up a fault

    now it most likely will open and close the dampers but seems to me this is a bit expensive set up to not be used properly

    makes more sense to just use a controler for the damper and let the stat control the condenser

    man those old hs14 were great units and the humidity controls were nice also if you but one on it
