I put these in just for fun. Green for cooling and red for heating. As i have my fridge in my garage i can see if it is heating or cooling from the kitchen
So are you stepping down the voltage to the usual 3V or something? Would love to know how you did this as due to a new fridge Im about to build my third STC1000.
Did you post these photos to support a discussion somewhere? If you did, I cant find it.
No they are the 240V ones, just hooked up in parallel to the switching relays. I just posted it into some thread as someone was asking for STC-1000 housings
