Title: Squirrel Cage Wiring
Post by: AirForcePOL on November 07, 2013, 09:52:34 AM
I am currently in the process of getting my garage hooked up to my owb.  The pipe is ran into the garage and I have installed all of the fittings on the stove.  However, I am not educated when it comes to thermostats and wiring the blower motor.  I am going to build my own setup as far as the HX and blower motor are concerned.  But once that is complete I don't know how to wire the blower up correctly. 

Below is a picture of the wires that come off of the blower motor.  The brown wires go to a capacitor (if I remeber right) but I will have to check tonight when I get home.  Then there are the 5 wires that come off of the motor.  Obviously as the picture shows, there is a white, blue, black, red and orange wire.  I would like to set it up so that I can have a switch box to allow for me to change the blower speed by the flip of a switch(s). 

Does anyone know how to wire these 5 wires to my power source or have a diagram that would show how they need to be connected?  Also, do I need some sort of relay panel that my thermostat wires will connect to to go from 24v to 120? There was a post on here a while back that showed a similar setup that I would like to have.  It had a series of 3 or 4 light switches in a box that depending on their positions, would change the fan speed from low, medium low, medium, medium high, high etc.  I found a diagram that I think showes how to do this but my wire colors are different than what is represented in the diagram. 

I'm lost, can someone help me out here?  :bash:  Thanks!

I would like to have something like what NewToIt has in this thread.

I used a Carson 3 speed fan switch. My blower is a 4 speed but I used the 3 lowest speeds... high was too fast.  The red wire was low speed, Black was high, blue was either med-high or med-low, and the other med-speed wire was either yellow or orange (I can't recall). I used a Dayton line voltage thermostat so I didn't have to mess with the whole low voltage thing. Seems to work great other than I think the line voltage thermostat isn't as sensative and you get a little more temperature swing.

Thanks! That looks like it would be the easiest way to wire it.  I have seen some digital line voltage thermostats that might work well.  I googled that part number that is on that sticker in the picture and pulled up the specs for that motor.  It is a 4 speed motor.  So if I decide not to use one of the speeds did you just put a wire nut on that wire and not connect it to anything?

Yes. And the white wire was the neutral. Another thing that I was shown was that I needed to restrict the opening into the fan because the squirrel cage will try to catch to much air and cause the motor to drag. I used a piece of galvinized tin with either a 3" or 4" hole in it. As you put the tin closer to the opening you can actually hear the fan speed up.
