[xswesx]

ok so I have this thermostat:

basically im a wiring noob and looking for someone to tell me where to connect what

the plastic thing in the pic has screws you can loosen to remove the wires. Where do I connect the thermostat too? What color to what?

thanks

What are you trying to control with the thermostat?

 

[foaf]

your pictures didnt come out. I assume you are trying to control a fan.

but, that type of thermostat has 3 lugs or connections inside the box. One is called common, one is normally on, one is normally off. you take one of the 110 wires that go to your fan, you have to split them up, normally there is a black (hot), a white (neutral) and a ground (green). So you usually take the black wire and interrupt (cut) it between the plug and the fan. one end of the interrupted end you put to the common lug, usually the middle one, and for now, if you dont know, just hook the other end up to one of the two other lugs, 50/50 chance you are right. Plug things in, and if when you turn the thermostat dial all the way to the hottest temperature (110 on that one) it turns the fan on, then you did it right, it should also turn off when you turn the dial all the way down. If the fan is off when the dial is set to 110 and on when its turned to the lowest temperature, then you wired it for a heater, so you just move the black wire from the one lug (not the middle one which is called common) to the other yet occupied lug.

or you can put pictures up better and we can tell you colors.

pics showed up for me, anyways here are the links

I tried 2 combos, both resulting in turning off all electric in the room switching the breaker . I set the thermostat to 110, the fan initially turns on ok. When I turn it to the rooms temp, it shuts down all power in the room.

first was black to black, blue to white, green to green
2nd: black to black, white by itself, blue to green


I looked at the diagram (T115).

It seems pretty strait forward, blue (cooling) connects to neutral, which is white.

The rest seems common sense, black to black, green to green.

I tried this again, hooking up black to black, blue to white, and green to green.

Same thing, kills all power when I turn the thermostat to room temp. Maybe i;m not connecting them properly? I am just putting the thermostat wires into 1 end of the plastic connector of my inline fan with respect to color.

Just hook the black wire to the control - the neutral doesn't go anywhere near it. If the control has a grounding lug you can hook a ground to it.

The way you are doing things now you are just connecting the hot and neutral together when you turn the switch on, and that's a direct short.

phrama not sure what you mean exactly.

I'd PM you but see no option, maybe my post count is to low


do you mind telling me what to connect to where?

Buy a C.A.P. CT-DMe controller,it runs heating or cooling apparatus,has a photo cel for day/night temp control,and a 3/5/7f degree margin built in. About $100.

Black from power cord -> common

Black to appliance -> blue

Ground -> green

White from power cord goes directly to appliance. You also need to hook two wires to the power cord ground. One goes to the ground on the appliance, the other to the green screw on the controller.

Sorry, but I'm not going to sign up for another sight to see your pics.

sorry I forgot you had to sign up to see pics. I'll upload one here:

as is 2 blacks, blue/white, 2 greens.

The plastic piece has a metal tube inside to connect wires.

one of the pics is the original fan wiring without thermostat

after a quick google search I wasn't able to find anything

do you have a link of this?

Get some wire nuts and hook the wires up like this:

Black from power cord goes to black on controller.

Black from fan goes to blue on controller.

White from power cord goes to white from fan.

All greens are hooked together.

I don't know how to make it any clearer.

Thanks pharmacan!

once i get some proper wire nuts ill try it first thing tomorrow

If you want to understand what you're doing...

The thermostat is just a switch - a fancy switch, but nothing more, nothing less.

The black wire brings power to the switch. When the switch is on, power comes out the blue wire then the other black wire takes power to the fan. When the switch is off, the power can't go through it so it can't get to the fan.

The white wire is a neutral. It completes the circuit back to your panel. The white wire doesn't need to be switched, so you just hook both whites together.

The green wires are ground - totally unnecessary to make the fan or thermostat work, but absolutely necessary as a safety precaution. They also need no switch and are just all hooked together.

There's nothing complicated about this at all. Essentially all you are doing is making (on) and unmaking (off) a connection through the black/hot wire via the thermostat/switch.

BTW - put a wire nut on the end of that red wire.
