Re: Carrier 30XA Liquid chiller Problems
Yes i tried it, since i replace the MBB with a functional one from another chiller and got the same problem "Start then Override" instead of "Start, Running and then override" i really don't know what to. If i disconnect anything then the system saw it, so all the boards and sensors are checked. I will try next to measure the 24V signals on all the contactors of fans, compressors....
