TESTING PROCEDURE & RESULTS
BACKGROUND: It is a good practice to test fans prior to installation to make sure they were not knocked out of alignment during shipment. An out-of-balance fan would be much louder than expected and have a shorter life span. I also wanted to test the humidity sensor's operation of the fan.
TEST SETUP: I set the fan on the bathroom vanity counter on several folded sheets of rug gripper material to isolate the fan body from the counter. I did this because in addition to testing the fan's humidity sensor trigger points, I also wanted to hear how quiet the fan was without the fan body vibrating on the counter. The blower intake was facing upward and next to the fan's humidity sensor I placed my digital humidity sensor. The fan was wired up as per instructions and an inline switch was installed to simulate the wall switch.
TESTING PROCEDURE: I closed the bathroom door and turned on the shower so it would fill the bathroom with steam and watched for the fan to turn on and record the humidity trip point. I then turned off the shower, opened the bathroom door and turned on my current bathroom fan to clear the bathroom of humidity. I then recorded the humidity level at which point the fan turned off. I did this three times. In addition, I triggered the fan's "Full Speed" mode by quickly turning the fan on and off.
TEST RESULTS: The fan turned on around 52% - 53% relative humidity, within the spec'ed 60% +/-10% range. It turned off around 45% - 46%, which wasn't unexpected due to hysteresis. The fan was very quiet when it was triggered on via the humidity sensor, but the airflow wasn't great. I did not have an anemometer to measure airflow, but could tell it was substantially less than the airflow in "Full Speed" mode. Also, the fan noise in "Full Speed" mode was louder as you might expect.
CONCLUSIONS: I called Delta tech support and spoke with several people who thought the fan speed in both modes of operation should be the same according to the spec sheet. I questioned them as to why the spec sheet refers to a "Full Speed" mode instead of a "Manual" or "Continuous ON" mode. They did not have an answer for that. So if there is indeed supposed to be only one speed that this fan operates at, then I have a defective unit. I am returning this fan.
This fan is a champ at turning on when the humidity goes up, but has a huge issue shutting off, despite the fact the relative humidity in the room is 55% or less. It will literally run all day and night at a slow speed if it gets in the mood. And I say it has moods because it's not predictable when it will decide to never turn off. It's probably a 40% chance it won't shut off. I can't trust it in the summer, as it might decide to blow all the A/C into the atmosphere.
In my other bathroom I have a Leviton wall switch for fans/humidity ($25 at HD) and it senses perfectly and automatically.
To Delta: Make the humidity sensor adjustable.
Very disappointed. We’ve had this fan for 5 months in a small bath for our boys. I thought it would be good to turn on and turn off automatically, as needed, since the boys would forget to do one or the other. However, apparently it’s not strong enough to handle the moisture from the shower and the moisture condenses on all the walls and drips down. Also, it seems to run on low speed for no apparent reason.
Controls seem to work well. "Auto" humidity sensing turns on once in a while, which is good since we have in a basement bath. Very quiet on auto, which is a very low speed. Quick flick of wall switch (off then back on) changes from auto to full speed. Seems you have to flick off/on again to go back to auto (or just off), wish it had a timer to return it to auto function. It is pretty quiet in both modes, but not silent in high speed. Also not load enough to cover any other sounds in a bathroom.
Has an LED behind grille to help know what mode, blue in auto, orange in full speed.
I'd buy again. Simple and effective.

Make sure your existing venting fits this unit.
All and all good unit. Has a 2 speed adjustment from the switch or from humidity level. speed one will show a green LED and speed 2 shows a yellow LED.
Again if you turn the switch on it will probably show green but as your showering and humidity starts to rise it will automatically sense and go into speed 2. Speed 1 quiet, Speed 2 is fairly quiet also.
This is my third purchase of one for different bathrooms.
