installing 3 in 1 on selectomatic wb-60-k6-d Howdy once again. I finally bought a supco 3 in 1 1/4 to 1/5. the old coil realy wore out and I cant find another one and It was suggested to buy one of these. I tried to get this thing to work and it does not work if I put color to color from compressor.
I drew a little drawing of how I got it to work. is it posssable for a compressor to run backwards? if someone can take a look at my chicken scratch and tell me if its ok or if im gunna burn it up running it like this. if i hook it up by color the compressor run for 2 sec then shuts off while the fan will stay on. if I take the wires from the old relay 2 black and one red and connect them together It works just fine. what is the purpose of the relay? to save the contacts in the t stat?
above is how Its wired and works
this is how it was wired
