Can the humidity sensor be disabled ?

It has been a while since I installed it but I saw nothing to disable the on/off controls. It would not work with a timer switch. I just leave it in full nearly all the time. I had to put a note on the wall to educate guests on how to use it. I still like it and would do it again. It is so quiet leaving it on is no big deal.

I dont care for mine and will be replacing it. The sensor works poorly and it doesn't move much air. I have it installed in a small bathroom and still have to clean mildew off the walls and ceiling because it works so poorly. I would not recomend this product. I'm sure you can get a much better fan for the money.

The humidity sensor is not on unless you turn it on. If you have a timer turn it on, the sensor will not be working.

The humidity sensor as well as everything else controlling this unit appears to be mechanical (no microelectronics such as computer control). Therefore it should restart instantly when power is reapplied. We have never run it with the humidity turned up full, but at 80% of full scale the house humidity goes over 50%. I really think if you set the humidity control to full, you don't have to worry about it turning itself off.

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 don't think this controller is that "intelligent". You can set a temperature and a humidity and it switches "on/off" to a plug that you plug your heater and mister into, based off the response it gets from the sensor you hang into your habitat. I didn't see anywhere in the programming for a timer.....but think you could get there by adding a plug in timer that will only run the controller at the time window you select. For that, the timer would plug into the outlet first, then this controller into it, then the heater and mister into the controller.

There are three sections. Top in sensor, middle is on button, bottom is off button. Any time it is turned on, it will stay on for 30 minutes unless you hit the off button. You can turn it off at any time with the bottom button, but if the sensor determines that it's too humid or moist in the room, it will turn it back on again. If the moisture level is normal, the on and off work the same as any other on/off switch.

The fan only switches mode after a quick on/off. I usually leave it in the auto mode, first turned on. It will speed-up as the humidity rises and later slow down or even shutoff if the humidity gets low. If you want it to run full speed just give it a quick on/off.

This works with a dial. The dial detects humidity. You can have it on full and then it just keeps running or less in which case it stops at a certain humidity. I don't know why it wouldn't go back on when the power came back. It isn't digital at all. But I don't leave it on when we aren't there either.

I used mine to interface to a zone controller so that would not be available as an option. I did not see any options on the programming of the stat. to control speed any way. My best guess from not seeing that option is that the thermostat would not control the speed but cant say for sure, I am not sure if your air handler has any sensors in it to detect if it needs to change fan speeds without a signal to do so from the thermostat, you could check on what actually controls the speed of the fan your equipment. This thermostat has tons of programming options and is the very best I have ever had or seen, but again I did not see programming options for speed control.

I could be an overheating issue.....when left in the on position for awhile it generates so much heat it turns itself off. I now have one that wont stay on more than 4 seconds on high and around 30 seconds on low..then the overheating sensor shuts if off. It seems once this happens it will always shut off instantly going forward.

My recollection is that there are buttons with a digital readout on top of the humidifier which allows you to set the humidity level or to turn it to run continuously. I set mine for continuous operation. Hope this helps.

As long as you install the power switch to fan where you can get to it that's easy to do. Turning the fan off and back on immediately starts the fan in high speed. Turn off switch for about 10 seconds to put back in humidity control mode. Light turns yellow for full speed and turns blue when properly reset.

I would not get this for the living part. The fan is always on and never turns off. So once you achieve your humidity level, the compressor shuts off but the fan is still on. I don't believe there is a way to turn the fan off. This is good for the basement to keep air moving. Some dehumidifiers shut off completely once the humidity level is reached. all will be somewhat loud like a window air conditioning unit. Most of the time, you will not need a dehumidifier in a living part of the house as long as you have an air conditioner.

The sensor and display are all one unit (the display and indoor sensor has the green screen, the other sensor show as a white square is for outside), so if you want to monitor the crawl space you need to have the display located inside the crawl space. If it were monitoring your crawl space humidity and it kicked on to add moisture the humidifier it would also kick on your furnace blower to circulate the humidity in your entire house (not just the crawl space, unless you have a separate system for your CS).

Hi Gary: Don't know what a humidity on setting is.... this is an exhaust fan, when turned on it runs and when turned off it doesn't. We are very happy with it, since it is extremely quiet and does the same job as the noisy fan we previously had.

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.

Yes. The bottom portion of the control can be pushed for manual on and off. When pressed, the fan will turn on for the set time unless the device detects excessive humidity. At any time the push pad can be pressed to manually turn the fan off.
