Software - Viking VUWC244DRSS Service Manual

The latest software is version 1.9. This software version will incorporate an additional 30 minutes of
compressor "off time" when 5 hours of accumulated run time has been obtained. The defrost period will
initiate at the beginning of the next call for cooling. At this point the compressor remains off until the
conclusion of the 30 minute defrost period.
