I bought this product along with Raven's AquaGuard AG-1200+ horizontal secondary drain pan, 24V safety/float switch and rectorseal SS1 horizontal drain (to avoid over-fuses). Bought. SS2 was installed on the secondary drain pan of the AC evaporator coil. I installed it myself which was very easy, along with another drain pan and float switches. I have a house on the second floor with a furnace in the attic. However, I asked someone else to hook it up as my setup has zoned snubbers and "added wire" so it's not the friendliest setup. I put the Aquaguard AG1200 in my baking sheet to keep my attic from overflowing. ss2 which I put downstream in my main to outside. So if one of them overflows, they turn off my air conditioner/oven to avoid property damage. I recommend any of these products for protecting your property as they all work very well for my application. Worth every penny for the moment you hope never comes.
