Hey guys and gals , do any of you have experience with the Johnson control economizer on York rooftops ? I had an economizer that when the molex is connected to the actuator it would open the economizer damper and keep it open even if there wasint a call for free cooling . It gave me "economizer communication error" on my board display . I called tech support and checked the wire from the "sabus" from the board to the module and it was properly connected and he told me my module was faulty . Just looking to see if anyone had similar issues .
