This is a relay, not a switch. Great Z-wave range.,
Verified Purchase(What's this?)
This review is from: GoControl Z-Wave Isolated Contact Fixture Module - FS20Z-1 (Tools & Home Improvement)
Once I was done scratching my head (the instructions were not great), the install was straight forward. By the time I was done, it seemed obvious.
I installed this to control a domestic hot water recirculating pump. It expected some difficulty because the boiler room is surrounded on 5 sides (ceiling and floor too) by concrete. No problems even though the controller is two floors up. At the time, I did not even have any other Z-wave to extend the signal.
The only negative is that it doesn't fit nicely in an electrical box. It would be nice if it fit through a decora plate, but it doesn't. I decided to surface mount it to a box with the connections inside the box.
This allows me to shut off the recirculating pump at night and also to shut it off during the day when now one is home. I have calculated a 3 month payback with energy savings from electric and heat loss avoidance.
