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
