Counting unique entries that meet certain criteria

I will do my best to explain what I am having a problem with....

I have a sheet that shows planned production at different work stations. Some of the work stations are listed more than once because sometimes they run more than one product in the same day.
Every other line is the planned production and the others are filled in after as the actual production
I have a sumproduct formula right now that looks if the line is considered planned production and then if there is a number greater than 0 planned on that day. The idea is to tell me the number of Stations scheduled to run that day.

Here is my problem- if a station is running two different products it gets counted twice.
I am trying to find a way that once a station is counted it only gets counted once even though they are on seperate lines.
Attached is an example of what I have with the formula and below that is what I am looking for

Thanks
