Used three neoStats with this neoHub to control three pumps on a very large domestic c/h system. Replaced three digital timers which were difficult to re-program every time the start / stop / run times needed changing. Now the client can change the settings from his phone. Sorted!

The product is excellent. Had a bit of trouble setting it up, probably due to my own issues. A quick call to the technical department fixed it. I'd highly recommend Heatmiser. First class service, and excellent support.
