There is one key element that you did not mention, aside from the above comments:
BLOWDOWN!
Depending on the chemicals you use, you must have some TDS level in the boiler that you are trying to maintain. If you maintain this at a low enough level, you will get zero scale in the boiler.
So this value must be specified regardless of the chemical program you are using (probably phosphate or chelant)
