It’s well known that the best-selling in.yj-3 is the nicest control system for small footprint spas. But the temptation to muscle it up and make it the best there is proved irresistible. With its boosted CPU, more memory and higher capacity relays, in.yj-3 now has the power it needs for new features… like an updated FLO circuit, LED lights for troubleshooting clues and dual phase CE configuration so it can be used anywhere in the world.
