I’ve had my Nest Thermostat working with my current furnace and humidifier for a few years now. The first year it worked great, my humidifier would run every time it was supposed to. The second year, it wouldn’t kick on when the furnace did, even when I turned the humidity setting to max. I ran the “test” function and that worked every time, so it’s getting a signal. The. It began working again for whatever reason. Now this year it’s not working again with the furnace, but the test is working like last year. Why would the TEST send a signal, but it won’t work when the furnace/fan kicks on? We’re getting dry throats almost every morning because it’s so dry in here…
