We just purchased a Pool Pilot Digital (DIG-220) from Salt Pool Guys. We've got a pool professional lined up to install the plumbing components and an electrician friend of ours will do the wiring. He was asking if there are any supplies (such as wire, etc.) needed to install the unit that are not included with the system. Does anyone happen to know? We have an existing electrical box with circuit breakers, but I wasn't sure if he might need something specific for the DIG-220. Thanks in advance for any replies.
