Memory card not available from company, more details under diag description 8/12/24 memory card replaced still throwing same code. I’m going to come out and work a standard thermostat and wiring into this system call customer to work with their schedule. When I come back to do that I’m going to call tech support again to see if they think it could be a motor or module or board issue. 8/13 tech support says either board or module. Will call and order both tomorrow from supply house to try each one. 8/16 replaced board, motor and module. Unit cooling at this time.
