Abstract

PROBLEM TO BE SOLVED: To allow easy program updating by providing a rewriting signal receiving means for receiving a rewriting signal of wireless signal, etc., and allowing a control program itself of an air conditioner which is housed in a non-volatile RAM to be rewritable using a wireless remote control signal. SOLUTION: A program signal received by a wireless signal receiving means 26 provided in a non-rewritable memory 27 is discriminated by an air- conditioning control data and a discriminating means 23 for rewriting program signal. If this discrimination shows that the reception data is an air-conditioning control signal, the data is sent to a nonvolatile memory 24 wherein no rewriting is possible through a control data analyzing means 22, and air-conditioning is controlled according to a normal air-conditioning control means 21 stored in the memory 24. Meanwhile, if the reception data is a rewrite program signal, the normal air-conditioning control means 21 is re-written by a rewriting means 25 of a main control program, for air-conditioning control according to a program after rewriting.

Whether the data has been correctly received may be determined by adding a checksum to the received data to determine the validity of the data, or by adding a CRC code or the like to enable self-repair.

The CRC (Cyclic Redundancy Check) is a technique in which code data for inspection is added to data and transmitted, so that even if data is erroneously transmitted, the original data is protected against some errors. This is a data inspection method that takes into account that the data can be restored.

If the program to be rewritten has been correctly received, the main control program rewriting means 25 transfers the program data to a program rewriting process (step 1008). It is determined whether or not all rewriting has been completed (step 1010), and if not, a series of these processes is repeated. When the processing is completed, a normal end display is performed (step 1011), and the program stops.
