any HVAC techs or electricians here? help

[broke]

i have a thermostat question; can a use a hard wired/ line-voltage "cooling" thermostat to control my exhaust fan? i found a single pole one for $15 new at my hardware store. the voltage and the amperages are the same for both. thanks for any help you can give.

what kind of fan ya got?

 

[broke]

i dont think it matters but its an axial fan from radioshak

 

[the Rock]

yeah it will work if wired correctly

Hard wired..white red/blue green orange?

most if not all go to furnace transformer..24 vac.

110 wired into transformer=24 volts unless its a static thermostat for wall heater. then 750 millivolt.

red/white =heat call..bluegreen/orange for ac=call..green alone controls stage for blower sometimes.

axilfan= 12 volts..need step transformer..24/12 volt...depends on fan..ive seen 24 volt ones..and 110 volt ones.

most are 12 tho.dc current.

yeah, actually it does.
if you were talking higher power exhaust fans there are some, like elicents for example, that really don't like standard speed controllers.
for your axial fan it really doesn't matter.
i would go even cheaper than 15 bucks.
you can probably pick up a corded lamp dimmer (extension cord with dimmer attachment inline) for 5 bucks including tax, strip one end and wire your axial to it. worked great for me all the way up to the larger muffin fans.

you need a Phason VTC-1D .

The Variable Temperature Control (VTC-1D) automatically controls the temperature in a room by adjusting the speed of variable speed fans. .. check it out...

Dongle69 uses one in her room. Works well for her and others.

humble i tried one of these lutron credenza llamp dimmers http://www.lutron.com/lampdimmers/default.asp?s=17000&t=17200 with a piggy back plug but my fan responded very poorly to it; it wouldnt slow the speed enough it just stopped! is there any difference between a lamp dimmer and a fan speed controller? are they essentialy the same thing just worded different?

thanx anyway globel; btw how much do those cost?

 

[broke]

yeah it will work if wired correctly

thankx rock im gonna give it a run

 

[globel]

there 250$ lol...... its good for like a warehouse or something... i bet it can handle alot of amps for that price ....lolz

 

[broke]

holy shit! my whole grow thus far has only cost me $100

 

[broke]

would one of these work? http://www.lowes.com/lowes/lkn?action=productDetail&productId=33905-1811-FSW1&lpage=none its alot cheaper than the thermostat and i worry that there would be a long time with no fresh air in the tote when using the thermostat. my fan uses less than 1 amp; its a 4" axial fan from radioshak (my growroom is a rubbermaid tote)

sorry, the link doesn't work.
that lutron is exactly what i was talking about. mine worked fine, i don't know why yours didn't. hmmh.

Yes, you can. A line voltage thermostat is just an on/off switch.

Cut the hot wire on your cord and connect the two ends to the appropriate terminals on the thermostat. You might need an intermediary wire to accomplish that, but that's the basic connection scheme. If you have to add a wire, just make sure it's at least the same size as your power cord because your current will be passing through that wire. You can connect the wire to your power cord with wire nuts, although you should make those connections inside a permanently mounted box with proper wire connectors and such.
