Indutrial Fan and Controller

[brent5631]

So I have two westinghouse industrial ceiling fans that I just recently installed. Link shown below.

FAN LINK

Last night I finished up wiring the controllers. Link to controller below.

Westinghouse controller

So the problem is when I turn on the switch the fans only move very slow. And changing speeds on the switch does nothing. All of the positions run at the same slow speed. So what could be the issue?

I have it wired correctly. My thought is the fans are only speed adjustable with resistor based controllers. But i can find any info to confirm that.

Any help would be great.

Thanks,

maybe replace that control with a regular switch and see if the fan goes full speed, if same speed check your fan wiring. if it goes full speed check your control ?

Yeah I'll check that tonight. I have a feeling this controller is incompatible but the engineer in me wants to see that in the spec sheet.

you know that manual says fan only goes maximum 240 ish RPM in their specification... right ? 240/60 = 4 rotation per second. not sure if that is a lot of lot less..... I never looked and count my fan rotation but I have a different one thought.

The fan info says it comes with a 5spd controller but the controller u linked to is 4spd. Why arent u using the controller that came with the fan?

Fan is stupid simple wiring. Power to controller, power from controller to fan. Neutral goes directly to fan. Controller does not use neutral.

If putting a switch in the place of the fan doesn't help, then the fan is bad. If it runs faster, then the controller is bad. Note that zero is off, one is high and four is lowest speed.

The fan instructions talk about using a pull chain switch to vary the speed, and reminding you to set it to high when using the wall controller, but I think they are very generic and that this fan does not appear to have any switches in it, not even to reverse it. Fan instructions also show a light wire in the fan but this fan is not designed to accommodate a light either.

Under the specs it says no pull chain, so go with what Charles says,my guess would be the controller since I doubt both fans are bad

I have three of that exact fan, and I have all of them wired to one switch. This is the switch I used and all three work fine.

Switch may not be capable of controlling two fans. Many of the cheap ones are not. I also wonder why the switch provided with the fan is not being used. put one switch per fan, then put a regular snap switch controlling power to the speed controllers. This way you don't wear the speed controllers out turning them on and off, and you get to control each fan separately.
