Mother /Son Logic

The program was developed in MCXDesing and there is only one single program for both units. There is parameter where the service

technician must select between mother or son configuration. The functionality is basically the same, but it changes on compressor

control because on Mother unit we need to use VZH and Oil Management features (for variable compressors) and in the son unit (fix

speed) these are disabled. The following flow chart describes the general control sequence.
