Hi, Does this run automatically every time the furnace fan kicks on? or does it have a Humidistat that determines how much steam to put out?

It is wired to the blower control and may run even when there is no demand for heat but since it is cooler now they often work at the same time.

It comes with a humidistat. I leave the furnace fan on all the time anyway but the humidistat is supposed to kick it on when it is on. I recommend installing it with 220 as it will make the unit more efficient. Other than that, I can't be happier. I live in Colorado and the humidity can drop under 20% in the winter. This unit keeps it above 45%.

It runs as needed. The humidistat will run the blowers for a couple of minutes every hour or so to check humidity levels through the return. I have had it in for a month now and can really tell the difference in the house. Depending on your panel location to your furnace (mine was relatively close) it takes about an hour or so to install and start up. I did put a humidifier water filter in line to help reduce the damage from hard water. Hope this helps

Hi Vincent, I just installed mine a couple weekends ago. In answer to your question, both lol. The control panel mounts onto your cold air return which you have to drill like a 3/4 inch hole for, so the humidistat that is on the back of the controller measures the humidity in your cold air return. It also wires into your furnace and thermostat wiring so it only kicks on when the furnace is running...

No, the fan does not run all the time. Once you have set your humidity level the unit will only activate to maintain the the desired level.

You can easily turn it on/off manually. When the fan is running it will only stay on for the set time interval.

It runs all the time after you turn it on. I have mine plugged into the amp, so when the amp is turned on so is the fan.

The quick answer is: YES. There is a small switch inside the humidistat that changes it to manual. The instructions made it easy to change over to manual. It also comes with a decal that you put behind the knob to change the way the knob functions. I added the outside temp sensor. Took a few hours to run the wire, but now the automatic mode means I do not have to worry about adjusting the control when the temperature changes, and I can keep excess moisture from forming inside my window. I am very pleased with both the humidistat and the Aprilaire 400 humidifier. Tom

Yes fan only runs when its heating or cooling. Unless you have it in the fan settling.

you have 2 screens one for fan to set it to on or auto. The other for heat or cool. Set either one to a temp that will make sure it won't come on and the fan to on and it will run continuously.

Hi, Frank. The gas/electric mode is a serting for heating purpose only. Some furnace equipment are natural gas powered, and some other electric. On this termostat you will have full control of the fan. In auto position it shut down or start up when the compressor shuts down or start up, and on "on" position, the fan will run constantly.

The fan runs continuously as long as the unit is turned on. I am not at the house that has this unit right now. But, as I recall, Auto Fan is just a continuous fan setting.

yes. you only want humidifier on when fan is funning. you will need a 12 v transformer.

It does not turn off complete, the fan still runs when it reaches the set limit, but it does not outputany moisture at that point. It turns on and off the mist only, not the fan.

Good morning from germany, no the is no auto function. The fan has to be turned on or off manually. It's not an air-condition,it's a fan with heating function.

Hi, I installed this in my son's house last fall. It has a separate humidistat control, which I installed in the return duct, about six feet from the furnace. It responds to the relative humidity in the house, which we set to 45%. Once set, it maintained an even level of humidity throughout the winter. My son & his family were very happy. No maintenance, except to replace the filter pad this fall. His house is about 1800 square feet. I give it 5 stars!

Fan does run at all times, however it appears to be thermostat controlled and will only really spin up when under load. Even then though when I am using this unit its pretty quiet and never really gets hot.

I would have it set to Auto. I find the Auto function is the best. It will automatically sense the odor or dust and the fan speed will speed up etc. Onc the odor or dust has gone down the unit will also slow down and go back to auto made.

Steve, The fan is great, It's controlled by the humidity, unless you need to have it on for other reasons, Then you can use the switch, it goes from automatic to manual. Voila. I would recommend this fan to All.

No humidifier function at all. There may be a fan-only function if you turn the thermostat all the way down, but you would be much better off with a "real" fan or a large air purifier.
