The numbers depend on numerous factors. It appears that one of your heater core sensors may have failed. Your refrigerent pressure (#7) should not read 192. It should read in a range from about 8 to 18 depending on the temperature outside. (14.7 psi per bar) You may be reading #8 which is your refrigerent temperature...then 192 would seem correct.

The thing you want to do is not turn the ac on and just power the system up after letting it sit for several hours, preferably overnight. Then the temp readings at 1,2,3,4 and 5 should be fairly close to the actual outside air temp if you are parked in a garage. If one reading deviates from the others by a large margin, you found your problem.

BTW, I'm not a tech but do ac work on my own vehicles when they need it.
