Moved into a new home and there is a Nelson Res 7 controller I the garage. I have no idea how to operate this thing and I csnt find the model number to try and and find a manual online. Any ideas?
The best idea is to count the number of zones you have and to replace the controller. Nelson sold off their turf irrigation division, and there is no longer any ownership continuity to some of the old stuff. Combine that with the fact that these controllers could permanently lose their display due to a manufacturing problem, and there is about zero pro interest in keeping these things alive.
