I have a system with a carrier zonekit2zcar installed. I recently added another output on my primary duct, installed a motorized damper, which only closes part of the way. Is there any way to increase the time that the zone control card send the closed & open voltage to the damper? If not is there available a dampner that will work with this controller? I have also installed a damper control card with power supply to allow for the two dampers.
