Can you turn off the motion sensor completely and just have the fan come on if the humidity gets above a set level?

I kept the motion sensor tucked into it's 'shipped' position which essentially disables that function and the fan only operates on a humidity level.

You cannot turn off the motion sensor. Even though the emotion sensor has a "zero" time setting, the fan will still go on when motion is detected but, that zero time setting will only enable the fan to go on for less than one minute. I have connected my fan to a wall switch that enables me to shut the fan off completely. That may be as option for you if you do not want the fan to go on when you are just entering or leaving the room. Just remember to flip on the wall switch when you do want the fan to do it's job for either bathroom smells or humidity control.

You would need to connect the fan to an external motion sensor that would turn off the power to the fan and then turn it back on when sensing motion in the room. It is designed to run at a very low speed at all times and draws an insignificant amiunt of power. It would be less expensive if you purchased a different fan and operated it from the motion sensor, then you would only be paying for one motion sensing circuit.

It appears this is only possible if you use the wall switch to turn the fan off and on. Using the controls on the fan (in the ceiling), you can only adjust the CFM (amount of air moved, which impacts the fan's sound) and the number of minutes the fan stays on once activated. However, you can turn the fan entirely off using the wall switch, and it will not come on using the motion sensor. If you want the fan to operate, though, the motion sensor stays on. So, to operate the fan as though it has no motion sensor, just use the wall switch to turn it on (when you enter the bathroom) and off (when you leave). That way the motion sensor won't bother you.

Sorry I'm late on the response! You can set the humidity level right on top of the unit.. I leave mine at 45% because I have a damp basement that stays very cool but humid if I didn't answer the question you were asking please let me know thanks for asking my opinion Pete

You can set the humidity on the control panel but the machine runs no matter how low the humidity goes. You can read on the panel the current humidity in the room. It will lower humidity. It will never turn on and off like a regular dehumidifier.

I wired in another switch in parallel with the thermostat, bypassing the thermostat, that enables me to turn the fan on any time regardless of the temperature. I believe you could obtain a humidity controller and wire it in parallel too.

The humidity level can be adjusted and the duration the fan stays on after being triggered is also adjustable, If the humidity raises above the set level the fan is activated. So yes you could keep the area at a specific level or below.

If you have not adjusted the Humidity setting to a higher percentage, the fan will continue to run. I had to set my fan to around 80% before the fan would stop running continuously. The actual humidity setting you select will depend on where you live and the ambient average humidity for that area. You should plan to go beyond the average ambient humidity to prevent the fan from continuously running as the humidity levels fluctuate day-to-day.

I am convinced that the fan should shut off periodically, although there seems to be no way to know when it will shuit off or how long it will be off-just that it does. Don, your fan may be shutting off at night when you are asleep or when you are not home to notice it shutting off. It's funny because you are concerned that the fan runs continuously and my concern was that my dehumidifier fan did not run continuously. The first rep's statement that the fan needs to run inorder for the unit to monitor humidity made me think I had a defective unit. The starting of the fan seems to have nothing to do with humidity but may be related to the passage of time, if that makes sense.

I have this model connected to a toggle switch, so I turn it on when needed. I turn the bathroom light and fan on separately, though I could have had them wired together to go on all the time. However, since it is a powder room, I do not need to use the fan every time I turn on the light. I could also have used a motion sensor switch to turn on both simultaneously, but thought that was overkill for my particular installation.This model does not have a humidity sensor, but that is available in the model number ending with "ACH".Hope this helps.

It must turn off, because when I checked it recently, I thought it wasn't running because I didn't hear anything. It had simply reached the proper humidity level.

I disabled the motion sensor by removing the grill, removing the motion sensor from the grill, placing a piece of tape over the sensor, and then reinstalling the sensor in the grill. This allowed me to operate the fan continuously at low speed, using the RPM control to set it as desired.

Yes, but it's buried in the 8 pages of instructions with very tiny print, and to get to the point where you disable the motion sensor, you have to go through a long sequence of setting other options. I did it once, but after a power outage reset the unit and the motion sensor defaulted back to ON, I disconnected the unit and put it in a drawer. I don't anticipate using it again.

Odor will not cause the dehumidistat to turn on. The fan could be turned on by lowering the humidity setting, and then turning it back up each time it was needed. A simple wall switch for the fan would be just as effective - and less expensive.

When the humidity level you chose is reached the mist turns off but the unit stays on.

You only need to run the fan for the length of time needed to remove the humidity in the area. Once that level is established, there is an automatic shutoff. It is pretty quiet.

I recently installed one of these, it basically works as a switch, so you can wire it as you wish. It has an in-built humidity sensor, and an external sensor to mount outside. You can switch a humidifier and dehumidifer and a fan. I configured it to start the a/c fan and 1st stage compressor when the humidity raises above 55 or 60% depending on what you set it to, as I live in SW FL. Works better than I ever expected it too, lowers my a/c electric usage drastically, and prohibits the mold/mildew smell you find in this part of the country!
