We installed a GHP around 6months ago in a hotel, worked fantastically, 2 weeks ago the client asked that we put t10 interfaces on the equipment to cut running costs. We installed the t10s on 10 fcus and ran the the distribution board for the electrician to make off through a run and stop relay. They did 9 fine but put one the wrong side of the relay and put 240V down the t10 line, I made one site visit last week and discovered the issue, I presumed it blew that board and potentially the other 9 boards to the control fuse so in the time I had I put every fcu into the EMG line and also the Cu ino the EMG I tried to readdress but setting stayed and HADD1 remained. Is there anything you suggest doing or is there a switch I have to use to tell the CU to address down the emg line. I did consider removing that fcu from the control line and try addressing but I just didn't have the time. Any input would be appreciated.
