The thermostat SHOULD prevent short cycling.
Assuming Mdk4020 is still on his original older Dometic control board, and T stat from 2002/2003, he might still be on the older bi-metal controls T stats. The mechanical and bi-metal T-stats were not smart enough to create a timing function to prevent short cycling. The older analog T stat may also have had the issue.
Even a new non-ducted AC with mechanical controls has the short-cycle ability issue.
When the electronic T stats came to be, many of them had the compressor timer to prevent short cycling.
The AC unit is original from what I can tell. I did not look into the thermostat however the unit is dated for 2002. I know for sure that I can short cycle it manually just by flipping it to off and then back to cold. I don't know if there is any logic for when the AC shuts off automatically though. I'm not familiar with these systems at all.
