• After the main control board application software is loaded into the mcb it must be configured for the specific control application this consists of setting the value of 28 configuration variables within the mcb these variables define things such as the type of cooling number of compressors and cooling stages and the type of heat if all of these items are not set appropriately for the specific unit the unit will not function properly the correct settings for these parameters are defined for a given unit by the unit software configuration code p.54
