What does 'Compressed air supply error (C - cooling) only' mean on my Tuttnauer 5050 and how do I fix it?

If your Tuttnauer Laboratory Equipment displays a 'Compressed air supply error (C - cooling) only' message, it indicates a malfunction in the compressed air supply. This can be due to the compressed air valve not opening because of a faulty connection or a faulty I.O. board, or the compressed air valve itself might be faulty. Check and fix the compressed air supply. If the problem persists, fix the connection, replace the faulty I.O. board, or replace the faulty valve.
