Inlet air temperature is at the inlet node entering the coil. The last warning here says the inlet air temperature entering the coil is 21.6C. So for the coil outlet temperature to be lower than 2C, the air flow through the coil might be lower than expected. Normal DX coil delta T is about 25 F or 14 C. If air flow is lowered, the delta T will increase. This is just a warning telling you to investigate why the outlet temperature is so low. Given a fairly reasonable inlet air temperature of 21.6 C (70.8 F) I suspect air flow is low, but that is a guess at this point. It would have been nice for that warning to also tell you the air flow per ton for help diagnosing the warning.
