Dehumidifier fan never shuts off. The only time it goes off is if I set the timer. But then it never comes back on even if the humidity is high. Is this the way this product works. Can only wonder how having this fan run all day and all night runs up our electric bill.

I do believe this one of those models that uses one display for both setting of humidity level and the timer , make sure you are viewing the timer function and not the humidity function , this is a very common complaint with these type as many times one sets the on time correct but then sets what they believe to be off time when they really are adjusting the humidity room level , there should be tiny lights that show function you are adjusting
Actually, you don't need to add a timer. The model you have already has a timer built in. On the unit itself, as well as the hand held remote. So you can set it either way. Set the amount of time you want it to run, when it reaches that time, it will shut Off automatically. One of the most important things to remember is to clean the air intake regularly. At least once every two weeks.
Norman, once the unit reaches the extraction level you have it set for, the unit will turn OFF automatically. However, depending on the humidity level in your home, it may take several cycles of running and emptying the bucket until it reached. After that, it should turn OFF, once the level is reached. Then when the humidity level rises above the setting it's on, it will start up again.
Since your unit is a Manually Controlled unit, there's no safe way to "rig' it to run on with a timer. The plug in wall timers are not rated high enough to handle the load of the dehumidifiers operation. Trying to use one, would fry the timer and possibly the dehumidifier.
If you want all the features you mentioned, you will need to purchase a new electronically controlled dehumidifier.
Depending on which mode you have the unit set on, will determine if it shots OFF entirely or the fan continues to run. In the Constant or Continual mode, the compressor will turn OFF, once the humidity extraction level has been reached. But, the fan will continue to operate, in an effort to keep the air circulating, so that if the humidity level rises, the compressor will turn ON and start extracting again.
In Timed Mode (usually 2 hour or 4 hour) , when the compressor turns OFF the fan does too.
SETTING THE MACHINE TO TURN ON 1. Make sure the dehumidifier is plugged in but turned off. 2. Press the button with the clock symbol below it. 3. Press the up arrow to set how many hours until you want the machine to turn ON. If you have pressed the button for more hours than you wanted then press the down arrow to lower the number of hours. 4. After you have stopped pressing the arrow buttons the display will return to the original display showing temperature and relative humidity. 5. After the above steps are completed the dehumidifier will turn ON in the number of hours that you have set (programmed).
SETTING THE MACHINE TO TURN OFF 1. Make sure the dehumidifier is plugged in and running. You should hear the fan blowing for sure. 2. Press the button with the clock symbol below it. 3. Press the up
arrow to set how many hours until you want the machine to turn OFF. If
you have pressed the button for more hours than you wanted then press
the down arrow to lower the number of hours. 4. After you have
stopped pressing the arrow buttons the display will return to the
original display showing temperature and relative humidity. 5. After the above steps are completed the dehumidifier will turn OFF in the number of hours that you have set (programmed).
This dehumidifier is built in such a way that the fan runs all the time;however the compressor works only when it is needed. These infos are not specified in the booklet. It does not work like the old ones.
I went back and rechecked. If the fan mode is selected, you can only set the fan at one of the three speeds. If you leave it in the fan mode, the dehumidifier will not come on.
Once the fan speed is selected, it will run at that speed in the dehumidifier mode. The fan will keep running, even when the dehumidifier (compressor) shuts down.
The only way to get it to turn off is to use the clock setting, which either selects how long it stands-by before starting , or how long it will run before going back to stand-by. DeLonghi calls it "stand-by," we would call it "off." DeLonghi calls unplugged "off."
I've never turned mine to stand-by, because it will never get my entire house down to 30% humidity (I have it where my air handler returns air to the basement). I live in the greater DC Metro area, where 75% humidity is considered extremely dry.
Apparently the normal mode of operation is fan on unless awaiting a clock start, or encountering a clock shut-down; either condition puts it into the "stand-by" mode.
If you have the fan icon selected, it is supposed to run continuously. If you use the mode button (not the fan button) to change to relative humidity (the water drop icon), the fan should only run with the dehumidifier.
