There are multiple wiring configurations included in the unit's instruction manual, I would suggest searching the web for an electronic version and downloading it to see if it includes everything you need, or contacting Honeywell directly.

If you have a regular outlet a few feet away it is cake. I gently cut a hole in the correct place in the air duct, positioned it properly (see directions) and screwed it in. We had an electrician hard wire it to the air handler and it works great.

I think you need to turn it on each time the power is off and back on. I am using it as an exhaust controller which uses engine vacumm to activate the exhaust. I need to activate it every time I want to make the exhaust more quiet.

Not sure I understand your question. The fan's on/off is controlled by the thermostat switch which is attached to the fan. You set what temperature you want the fan to turn on/off and it will operate at that temperature.

This controller uses a wireless signal to communicate between the switch and fan. It is possible that a similar switch nearby is also controlling your fan. It could be at a neighbors house. You will need to change the code on both the wall unit and the fan unit by changing the position of the very small switches inside. This will get you to a unique code that will not interfere with other switches.

I do not have an answer. An electrician who installed the light and fan provided information regarding the controller to be used.

On the model that I have the fan can be turned on seperately, but not by the timer. It must be done manually.

I have no idea but, I did call customer service regarding my wiring situation, and they gave me a configuration which made the device work perfectly. My guess, the Fan only feature would not work.

I don't have a dehumidifier but I have it set to kick on my HRV for humidity removal. It should also work for the AC as long as your furnace allows the hookup, since it does sense humidity.

Yes, you can run a dehumidifier with this controller and you would only need a auxiliary contact if the dehumidifier exceeds the rated amperage of the controller.

Both of the other answers are wrong. There is a "Dry" mode for dehumidifying. You can download the operating manual from Friedrich's site to verify that for yourself, but here is the relevant section from the manual...OPERATION MODE SELECTORPush the `Mode' button to rotate betweenMoneySaver → Cool → Fan → Dry modes.(select Dry mode for dry/dehumidifier operation)

I have the same problem my dryer is in the garage and the duct work is under the slab. How did you configure the set up or place the fan?

I added a fan controller. This keeps it very quiet at the operating temperatures.

When the unit cycles off, the fan does not run. However it has a very annoying design fault. Say you set the RH (relative humidity) at 50%. Once the dehumidifier reaches it, it will then turn off, but it is usually for less than a minute, since it doesn't take long for the humidity to climb back up. It doesn't sound like a big deal, until you realize how loud the machine is and how distracting it is when it is going on and off every 3 minutes. But if you leave in a very humid place (I live in Miami, FL) it is always running until the bucket fills up.... so no annoying on/off for me. When the unit cycles off, the fan does not run.

Hello - I realize that you posted this comment some time ago, but I'm hoping you may be able to help me. I bought this fan a couple of months ago but only recently hired someone to install it while I was away on a trip. Turns out my 1948 house has the 2-wire electrical, so my contractor simply purchased a different fan. Now I can't return this one. To use it, what did you do? Did you purchase a different type of remote and if so, what kind? Thank you!

This controller has a relay controlled by the alarm set points. So you could control a 120 VAC contactor coil but then you wouldn't have an available alarm function. Unless you then used the main SSR channel to then control an alarm but this ass-backwards. Better to find a controller with double relay channels or just go with the SSR. I suppose you could use an SSR to control a contactor coil but this getting unnecessarily complicated.

The unit specs are wrong on the website. The spec sheet on the controller it self calls for 12 volts ac for the power input. But it will run on 12 volts DC. It's just a relay that turns on and off when a certain temp is reached. So a standard 12v fan should work just fine.
