DIY Universal Relay: Thermal Shutoff/Flip Flop/Time Activated Outlets etc...

[The Dopest]

ok i said i would do it in my Thermostat Controlled Outlets thread and here it is! i have to rename all the pics cause apparently if you upload a pic with the same number sequence as a previously uploaded pic, the old one gets replaced. i didnt learn my lesson on the above thread and lost a few pics to more recent uploads i know now so on to the show!

firts pic will show the shoppin list acquired mostly from lowes but some home depot too. the pic was left large so you can read the numbers on most packages, if there are any questions let me know.


be back shortly with the assembly pics and many different uses...

Looks like a good materials list.

Thermostat Controlled Outlets

Thermostat Controlled Outlets

this will be the guide for thermostat controlled relay outlets. you can use it to either supply power at a certain temp or shut power off at a certain temp by simply pluggin in your power cords and setting the thermostat to your desired temp.

first i mounted the relay to the 6"x6" metal enclosure



next i mounted two metal outlet boxes to the 6"x6" using 1/2" box spacers



wiring the outlets came next, i use crimp type connects throughout.



white outlets are wired to number 7&8 on the relay or the NC contacts. grey outlets are wired to the 5&6 or the NO contacts.



crimp connections inside thermostat


the short female cord is the trigger wire and has the black wire attached to the #4 contact on the relay and white attached to the #2 or coil contact on the relay. the long male cord is the main power cord and has the black wire attahed to the #4 contact along with the black trigger wire and has the white wire attached to the #3 and jumped to the #1 contact on the relay. not shown is the ground that i used in the metal box behind the white outlets. ALWAYS ground your work!


if you plug the therm in the short orange cord and plug the long one into power, the white outlets will come on. once the temp rises above the set temp, the relay activates and flips power to the grey outlets. meaning if you want to use this for thermal SHUTOFF plug your lights into the grey outlets and set the temp to say 100 and if the temps reach 100 then the grey outlets will shutoff. if you want to use this as a thermal TURNON the plug fans into the white outlets and set the temp to say 75 and the fans will remain on untill it gets below 75. if anyone need a wiring diagram let me know.

Even though I could do this myself, this is EXCELLENT INFO for those who couldn't without your D.I.Y. GOOD SHOW Dopest

Nice, flexible device. I like how you provided outlets for both the nc & no contacts.

Lets just not forget that the relays and wire used need to be rated for the load they will carry. This set up is good for light duty, but if your going to switch larger loads make sure youve got the right parts.

I've worked with those contactors before, should be rated @ 30A, as long as you rate the wire/outlets the same you should have no troubles

Excellent info as always TD......... ....... At the risk of sounding ignorant,how would I set my lights up on the timer(got 3 in each of 3 different rooms) as well as being plugged into the thermal cutoff.........It`s an awesome idea to be able to shut lights down if environmental control failure occurs as well as being able to control intake and exhaust fans at will for major air exchange...I guess I need 6 of em......Figure up the invoice and I`ll remit funds to the nearest p.o.box of your choice...........lol...............You da man TD.........Peace........DHF........
