Step 07 checks the indoor units. A faulty indoor unit is shown as 07, then the indoor project number, then its fault code, in rotation (for project numbers of three digits it shows the first two digits, then the last two, then the code). 07/oC means no indoor fault and the next step starts after about 5 seconds.
