Thanks.
sorry i missed this reply... the thermostat in the pictures goes down to 45, which is fine for me as i'll only be using it for a fermentation chamber... i guess if you want to lager, you'd have to get one that goes lower or use a traditional temp controller... i don't know if there's any way to modify the thermostat to go any lower.

got the SSR in but i'm having issues getting power to it... i don't know if the DC plug i found in the basement doesn't work anymore or what but I can't get any power to the SSR so it won't switch the plug... i'm gonna go to the salvation army tomorrow and see if i can find another DC plug to try out...

edit: does anyone know if the little red light on an SSR should always be illuminated or does it just glow when power is being transferred?

I am a diy'er as much as the next guy but I bought a new pre-wired with piggyback plug controller that goes from 30 to 100 for $35 from CHI.

I paid $29 delivered for my double throw prewired JC-A19 off of e-bay.

I know you're only supposed to put milk on corn flakes but this is just an fyi.

too late for me now, but thanks for the info.

does anyone have experience with the SSR light and whether or not it's always supposed to be on or just when it's transferring power?

edit: found out by trial and error, the light only comes on when the thermostat clicks on.

I did this same thing, with a Rite Temp thermostat, it cools down to 30 degrees, and has worked perfectly for me, it can control both cooling and heating, you just need one extra relay for the heating side.

However, living in Texas, haven't needed the heating side yet.....

cool, thanks for the post. so you took out the jumper wire from Rh to Rc in the thermostat, got a second SSR and did you have to splice the DC adapter to connect to both SSRs? hopefully my question makes sense. also, how do you determine which wire is the (-) on the DC plug and which one is the (+)? i'm running into some problems getting mine to work, i don't seem to be getting any power to it...

Good project, I did something similar when I built this http://www.homebrewtalk.com/f51/fina...chiller-65929/, but I think I had more detail in here http://www.homebrewtalk.com/f11/if-i...me-brew-51604/

I didn't have to split the DC adapter going into the thermostat, I left the jumper connected on the thermostat.

Then I ran a wire from the Y terminal on the thermostat to the cooling relay, and a wire from the W terminal to the heating relay.

The other end of the DC adapter was split and run to both relays.

Then I just used one relay to control one plug of a standard household outlet, and the other to control the other, just have to remove the jumper from the outlet.

Plug your refrigerator/freezer into the cool side, and a space heater or equivalent into the heat side. You still have to flip the switch on the thermostat, but I have seen some that switch automatically.

BTW, I didn't use solid state relays, I used automotive relays.
