Fan speed controller

[Gangabiss]

I'm having a little trouble figuring out exactly how to wire this thing in.

It's a tiny little box with a twist button and just 2 connectors on it.

Now the actual cable for the fan has 3 wires: blue, brown and green striped.

I assume due to there only being two connecting points that only 1 wire should be used, correct? So do I cut one of the cables near the end and run the speed controller inline on just 1 wire and leave the other 2 untouched?

Sorry I know this sounds a bit remedial but I don't want to start a fire or anything.

I just assumed there would be 6 connection points on the box...so you could just chop the whole cable in half and link all 3 wires through the box...this is why I was surprised to find just 2.


Help a guy out please


Edit: I know that the green striped wire is the earth (i think ) but will it matter which of the other 2 wires I use to wire the controller into?

The blue and brown from the fan go on the go to the connectors and the green striped wire is just a ground.

 

[Gangabiss]

You mean I wire both the blue and brown to the same connecting points? Wouldn't that mix up the positive and negative or something?

 

[Gangabiss]

Like this?

No bro,I think I misunderstood,I thought you only have 3 wires from the fan and two connectors.If so take the colored wires from the fan to the two connectors,the striped green wire is definately a ground.If its different,I really dont know how to help but someone will

 

[Gangabiss]

Sorry man but I don't understand what you mean...I can't just connect all the wires together can I?

Anyone else know what I'm supposed to do?

I thought you said the fan only has 3 wires coming out of it,why does it show 5 wires in your pic?

 

[Gangabiss]

That is not the fan in the pic, it is the controller wired inline with the fans cable.

hey please dont connect all the wires together. in most cases i know of the controller goes inline on the hot wire. im unsure which color wire that would be for you but you usually cut the one hot wire and attach the controller inline on it.

please be safe and dont listen to anyone like me who is unsure. im mainly sayin dont wire all the wires together. someone may be able to verify whether you only use the one hot wire.

 

[Gangabiss]

Thanks Dopest that was pretty much what I thought.

Can anyone confirm this to be true? Also, which wire is the 'hot' one? (uk 3-pin socket)

take one wire from the fan and connect to blue wire on controller with a wire nut and wrap with electrical tape, then take other wire from fan and connect to brown wire with wire nut and wrap with electrical tape. plug in fan it should come on. if it doesn't just reverse wires, hot goes to hot and common goes to common. just wrap the ground with electrical tape since you won't be using it .

The Green is the ground and must be connected directly to the rounded prong on the power cord. Connect one wire from the speed controller to one spade prong on a power cord and the other wire from the speed controller to either the blue or brown from the fan. Now connect the other wire from the fan to the other spade prong on the power cord.
Effectively you have placed the speed controller in line with either hot wire into the fan. Since AC current flows in both directions (Alternating Current), it really doesn't matter if the fan controller is on the neutral side or hot side wire (for an inline fan NOT lights). It also doesn't matter which spade prong on the power cord goes to which hot wire (blue or brown.)



hope that helps

 

[Gangabiss]

Ok now I'm confused...

You're saying I need to use both the blue and brown 'live' wires and have 2 wires going to each connector on the speed controller?
Wouldn't it just bypass the controller if you have 2 wires connected to the same connector? I mean the current wouldn't have to go through the device would it? It would just jump straight to the next wire and keep going full speed.

 

[Gangabiss]

Sweet thanks so much HIDEyourBUD!

You have made things much clearer for me

 

[HIDEyourBUD]

Glad I could help man. Now are you ready for me to go into auto slowdown circuits for when your lights go out?

 

[Gangabiss]

lol er......I have no clue what that means.
I think this is the most technical I want to get with my grow to be honest

I appreciate the suggestion Kinko but I've already wired and taped it all up.

Thanks for all the help guys
