PROBLEM TO BE SOLVED: To provide an air conditioning system which can make it easy to update an old control program for an already-installed communication relay device, and can sufficiently exhibit the function of a newly-added communication relay device. SOLUTION: The air conditioning system comprises a version judging means which makes judgment as to whether version information on control programs provided with communication relay devices 3-1 to 3-3 is new or old, and a program updating means which updates the old-version control program to a new-version control program, and, for example, actuates the version judging means and program updating means by an operation of an operation switch 14c of an operation part 14 provided in the communication relay devices 3-1 to 3-3.
