Only by timer. But you don't want it on for more than an hour or two as the water dries out

You can just plug it in or do as I did. I bought a electric timer for $ 10 to plug the unit into. Works great.

timer function is independent of the on function. So it will run continuously if you just turn it on.

No, you have to press a button to set the timer - for 1, 2, 4 or 8 hours at which point the fan will turn off. You can't set it to turn on.

No, you can only use it to set the number of hours it should stay on before turning itself off.

No. It is manually turned on for a specific amount of time. It doesn't have a timer mechanism to set a time for it to start.

You have to manually push the button on the power supply unit to start. Even you use a timer, you will still need to push the button.

No you don't have to use the timer. All you have to do is push the button in do not hold it in this is what sets the timer.

It neither has a timer nor an on/off-switch. It is operated by plugging it into the outlet to start it, and plugging it out to stop it. In this sense you can time it by purchasing a timer-unit for a few dollars to put on your outlet.

Don't need a timer switch. It's based on turning the power on at the switch. It toggles between sensor and full speed mode. If you set it to full speed mode and want sensor mode, just turn the power off and them back on. Works great for us.

no, you turn it on by pressing the speed button, then can adjust the 3 speeds, timer up to 8 hours, and off button.

You can't set it to turn on at a certain time, unfortunately. You can set it to run for a specified amount of time and then it will shut itself off.

push it once for one hour, again for 2 hrs, ect. If you push it once and hold it for 2 seconds it turns on without the timer, doesn't turn off until pushed again. Works great, and it doesn't make noise

No, this is a strictly mechanical switch, you need to manually reset timer after power failure. I have been using this combination of timer and electric water heater for close to 30 years and believe it is even superior to the current fad of "on-demand" heaters.
