I have a 24V STC-1000, and it works well on 12V! It even has a rectifier on the input! However, after setting my temperatures, the heat/cool lights don't show up at all, and there's no output. Did I accidentally disable the outputs or is my unit defective?
The input power is just for powering up the unit. The cooling and heating lines ARE NOT linked with the input power. Cooling and heating lines are just ON/OFF switches that are activated or deactivated by the unit with the blue relays on the board. You can run 220v or 12v through the cooling or heating lines as long as you dont exceed the current limit (A - ampers). The current limit is marked on the blue relays or on the unit data sheet. Or in this case the current limit is also marked on the unit itself and it is 10A @ 220V Hope you got your answer :)
@@vilpzz I have the version 2 board wr 032 v2. it works the same. Remove the transformer. Viewed in the same direction as the video above. The two top connections of the transformer are -12V on the left and +12v on the right. Solder two wires similar to the above video to the screw terminals. Don't forget to label the controller as converted to 12v dc. Accidentally connecting mains voltage would be very dangerous.
Thanks.

The unit works as a relay switch, you only need to run 1 wire through the unit
I have a stc 1000 032 use 220vac power, i want change to 12vdc power but i don't no what to do. Can you help me!
The video shows you what you need to do.
Did you find out how to change the compressor delay ?
You have to change the firmware on the controller chip
does this make it input and output 12v

@@vilpzz how do you do this for the version 2 board cause its different
@@jaredkarpinski3460 I'm not sure which board you mean? I have only worked and done the mod. on this one.
