NE CO | You can replace with a black box like above, but without having the large silver fin controller as well, your won't get much much more and since you have an older green box now, you don't have the silver box or even the right harnessing to plug one in.
Your best bet right now is to just upgrade to the latest controller which can do all of the advanced readings just by swapping out the controller with the new silver wedge box that came out here last year, part AA102798. | |
