There are 3 criteria on which you can set a condition for free shipping:
Total (price)
Weight
Item (number of items)
For each one you can set a Min and Max limit.
When you set both a Min and Max limit, logic is based on 'AND'. Meaning to have free shipping, product must be over Min limit AND under Max limit.
But if you set conditions on 2 different criteria, logic is based on 'OR'. For example, if condition on total price OR condition on weight is fulfilled (only one is enough), then you have free shipping.
If you want free shipping if weight is under 3 AND total over 150, well this module can't do it as it is.
