well i got at a resturant that just closed down. they used it for there walk in cooler. i saw ranco and electronic temperature control and i was like "I'll TAKE IT". it's not like i can really return it, so how would i got about converting it. is it something i can pick up at radio shack? if it's not worth it to convert i have a pair of johnson controls that i use so i could just use the ranco as a paper weight or something. thanks
