Hi, I need help .. I have 3 PA2 connected to AE5 .. Two ultra control the pumps (Laing DCC) and the third ultra controlled the fan (6) of the radiator .. A few days ago one of the three PA2 broke and I bought a new one (standard not ultra) .. The day has arrived and I updated the firmware (1005) for all three ... But the new is not recognized by AE5 Aquabus but I had to connect through USB and use the manual control output ... I have done several tests changing the address Aquabus ... No results ... The two old ultra (pumps) work, however, perfectly mode control curve .. What could have happened?
