Can I use this to control a fan with a 2 HP motor?

This control will not work with slow statting motor! I believe my answer is no.

I don't know; but if the fan motor draws less than 20-amps, I would think it can.

it will work as a off and on power control, but not as a variable step controler such as needed for a multi speed device with an amendum such as a varible intensity light. if it is a single speed fan, with a single intensity llight that is controlled by a " pull chain " switch wired into the fans power connection, you are probably " O.K."

Yes,you can use this to control a fan. This will explain how to wire your configuration. Your fan is the LOAD in the diagram. http://ukrferma.nethouse.ua/static/doc/0000/0000/0151/151383.iabtisqg38.pdf

yes. a timer can be used. typically, the timer would be used to control just the fan motor if you have separate switching for light, but I suppose you could time out both at same time if a light is included.

Yes it can , I have two fans running off of a speed control, and it works great

No, the fan needs to have two speed capability. There would be three / four wires.

I've got one controlling two motors, one running forward and one in reverse, at the same time. As long as you don't go over the amp rating you should be good.

You could use 12 VDC power (like a battery) to power the controller and the fan is then powered by the controller.

probably ! my fan had only 3 or 4 wires and i figured it out. I am not so mechanically inclined, but I was willing to try to fix my fan. It had only 1 speed ! this did the trick !

If the fans are 4 pin molex yes but you will need a splitter if you have more than 1 fan. If the fans are 3 pin your going to need a 4 pin to 3 pin splitter. As for the fan controller yes you can use this to power it as long as it has a 4 pin molex connector!

Yes it will cause the fan motor to run slower than it should , which will burn out the motor.

A 2 hp motor @120v draws 20 amps. The rating on relay contacts is only 15amps. So no.

it would have to be a small 12 v fan, with low rpm. I bought this for a 30 rpm motor, which turn very slow at high speed, if its a cooling fan, it will not work for you, as cooling fans turn at very high rpm. I suggest you get the specs of the fan, before buying a condroller.

Make sure it is a 5 wire for 5 wire swap. It will change the fan speed. I would be concerned going from 2.5 uf to 6 uf. Don't think I would do it.

The specification states that it will control up to a 3 Amp fan. Check the amperage of the fan motors and add them, if the total is under 3 amps you should be OK. Most bathroom fans are well under one amp so it should run 2 or 3 without an issue.

I don't know why not, it is just a switch like any other. check the amp rating on the fans to make sure the total doesn't exceed the rating of the switch.

It is 12 volt DC to operate it and the contact are rated at 150 Amps @ 12 VDC. It could be used in an engine starting application, but is probably "over kill" for use to operate a fan. I would think a smaller relay would be better for a fan.
