Near Intersection of I-35 & I-90 Southern Mn. | Later correction. I was thinking of a different model and the 4600 does have the ability to work with a single product as well as the 4400.
So either a 4400 or 4600 could control the NH3 bar in place of a 440 but the wiring would be considerably different. You may have been hoping that it would just "plug right in" but such is not the case.
An adapter could be used to continue to use the existing wiring on the bar but often it is a good time to "start over" with new wiring anyway..
