I personally would be wary of heller1707EXL and as I have many customers that find them not too repeatable due to cross profile variance... MarkIII not sure about. Always check perspective oven for this if you can...simple trick is to run blank PC

There is a oven setup wizard on my 1809. your oven probably has one too. there you should be able to adjust blower speed for each zone.
