Hunter i-core dual

I just purchased a 2nd gen Rachio. I have a Hunter I-core controller. Just opened it expecting a straightforward installation but the main controller has a Hunter Dual controller inside it. It seems this is a controller that allows only 2 wires to be used for my 16 station system. In other words, I don’t have 16 wires for my 16 stations… only 2 wires. Is this incompatible with the Rachio??

@johnnybmd - based on my quick internet research it may be incompatible.
