This relay works perfectly for the Nest thermostat and Aprilaire Whole-House Humidifier with the simple 24VAC water solenoid/valve. Nest will not provide any information on connecting the two systems, and will only direct you to a $$$ professional HVAC company. The Aprilaire representative was sympathetic and directed me to search the internet for a relay, and online HVAC or DYI forums.

I added the wiring diagram that works for my system, as a picture for this relay, and included a HVAC forum link in the comment section of this review. This information probably does not suit all systems, but it relates to 90% of the systems in the Midwest. Using the wiring diagram as shown with the "H" or humidifier power tap on my Carrier furnace only turns on only when the heat cycle is running. So when the Nest sees a demand for humidity, it closes the new relay, starts the fan, but there's no power to the water solenoid until the heat kicks in. Consequently, the fan may continually run without providing humidification.

This alternative does not replace the Aprilaire Humidistat with outdoor temperature monitoring, and automatic turn down for temperatures below 30 degrees, like the Aprilaire RP-58 Automatic Digital Humidifier Controls. These automatic humidity controls are far superior to the Nest for control winter humidity. The Nest requires you to monitor the outside temperature, house humidity, understand what adjustments are needed, and then use the Nest app to change the humidifier setting.

Thanks Aprilaire for making reliable systems and having great customer service. After researching this problem, I wish I would have bought a less expensive WIFI thermostat and the RP-58 humidistat.

Great product for the Nest thermostat which I installed in my home a few months ago. It works perfectly with the other components.

Worked perfectly to hook my Aprilaire 600 Humidifier to my Nest. Below is a link to a Thermostat Forums line of posts that really helped with my setup.

It's just a part but this has made me very happy to have it working. Used this with the Nest thermostat to finally be able to control the humidity with the thermostat, instead of that cheap, senseless switch that came with the Honeywell 360 humidifier. I couldn't get it to work at first, as I wasn't getting enough voltage but that was a Nest problem, finally fixed by a new base (no idea what's inside that ring that would do that). Anyways, it's nice to have things working the way they were intended, even if it took a year.

Just what I needed for humidifier hookup for my nest thermostat to work properly. Single wire from nest to dual wire solenoid.
