For Fan control, I would assume 1 is slow (low speed), and 4 is high (fast), is that correct?

This switch works great for lights and fan. Down is off, up is full speed. 4 is the fastest

No. It's just the opposite. At least that's the way it works for me. I had an electrician install it for me, too.

Three speeds. I Have seven of these fans and love how well they work and how quiet they are. I'm finding that they are really helpful in cutting down on air conditioning in my desert home.

The fan blows air in one direction. If it's blowing in and you want it to blow out, turn it off, lift it out of the window, turn it around and place back in the window. Controls are on both sides so you can still adjust/turn on/off. You can run 1, 2 or all 3 fans via a switch. There is no speed adjust (slow/fast) but there is a thermostat adjustment.

No it is just an on/off switch. But you can control the speed by buying an speed control rheostat. That is what I did. It costs $50 and amazon has the unit the fan maker recommends.

Correct. I use two of these to run 4 case fans.. 2 in front and 2 in rear. My motherboard controls the speed as designed. These are 4 pin connectors for PWM style fans. Don't be fooled as 1 connector only has 3 pins, this is by design to 'ignore' 1 fans speed signal to not 'confuse' the motherboard. Enjoy!

5 positions - 1>low fan - 2>low fan w/light - 3>high fan w/light - 4> high fan - 5> off

Generally the first 2 wires in a 3 wire fan plug are the DC hot and ground, the 3rd wire is used to read the rpm of the fan by most newer mother boards. If you are replacing the unit in a PC that has some sort of temp control that varies the fan speed it will take care of the speed control automatically. Otherwise it should be full power all the time in systems without fan speed control.

Yes. From very low to hi. The speed control is on a "roller switch". Love this fan!!!!

Yes it can. There are three settings for speed and three for pulsing. By putting it on low and normal you can have constant low fan speed. This item was a steal at the price I bought it for.

yes. can select low or high (constant) run, or can use thermostat 60 to 80 degrees and fan will turn off at desired temp and back on to maintain it. Fan does make A buzzing sound at low speed, but not high speed.

No, just on and off. I would say compared to most fans it's basically just on low but moves air around a room nicely.

Yes, it has three settings both in, both out and one in/one out It also has three speed settings which are electronic, so it starts on low when turned on. The speed settings are independent from the fan direction

I set my fan on max and then removed the chains from it as this controller works great at controlling the speed of the fan from low to high. It has 4 speeds instead of the 3 most fans come with.

It is, but it will not give you much adjustment. I tried plugging this into the controller and to start the fan it had to be almost full on into the high range. Adjustment was very minimal, it was basically on or stop, couldn't even back it off to less than half of the high setting before it would just quit. So yes, but if you want very fine-grain control you may be disappointed.

I don't know. My fan and light like this is controlled by a wall switch and pull cord. I switch it on at the wall, and then control the light and fan speed by the 2 pull cords.

I cannot tell you the dbA reading, but I have two fan speeds. The fan speed is controlled by an external switch. I suspect you could even have a variable fan speed control if you purchased a variable power supply.
