    Thanks for posting this. Installed the same humidifier today without any issues – worked the first time. One change that I made was: my Common/C terminal is already connected to the Ecobee EI’s 24V terminal block, so I just kept the wiring inside the EI from the humidifier’s solenoid and connected one lead to the ACC1 and one of the 24V part that lead to Common/C.

    1. Hey, Kevin. Congrats on the successful install! And yes – connecting to the COM terminal inside the Ecobee EI is just as good as connecting to the COM on the furnace’s control board! The COM is “common” to a lot of connections! :)

    I’m not sure I’d bother with this. Looking at the statistics of how efficiently my bypass humidifier adds moisture without the furnace supplying heat, it doesn’t look too good. In about 90 minutes with the furnace and humidifier running nearly constantly, it raised RH by 6%. That same day, in a 75 minute period, with just the fan and humifier running, it raised humidity by only 1%. I can even find periods where the humidity drops with the fan and humidifier on. I’m turning on the option to humidify only when heating. It looks like a waste of water and electricity to do otherwise.

  3. Going to do this today. I picked up a Trion Mister-Mini due to space constraints. We’ll see how well it works.

    Not sure what happened to my set up. I have 2 stage heat and single cool. I hooked everything up as shown in the install manual. After registering etc, everything worked great. Then I tried to hook my dehumidifier. I again followed the install in the manual. Hit the power and all looked good. First time furnace called for heat, humidifier kicked on, but seconds later, smoke was emanating from the interface board, I took off the cover and saw that little green thing next to ACC3 bright orange, then it popped and caught fire and I hit the breaker off! I assume that port is fried. But what the heck happened??? Do I dare hook it up to one of the other slots? I don’t have plans to hook air to air up as you can’t turn it on from mobile only at thermostat. May want to hook up try switch for warning of sump pump. But for sure want humidifier hooked up….help,please
