I would definately buy this relay again.
Builder wired our Aprilaire 700 Air Purifier incorrectly (it's only supposed to be on when the HVAC blower is running). Great service from Supply House, as usual. The part arrived quickly. Installation instructions were easy to follow. Our system works correctly now with the current sensing relay installed. I expect the electric bill to be a bit lower and the ionizing wires to last longer. Thanks for your help!
