Wiring a new Hayward MaxFlo VSP to existing Aquaplus/PL-Plus/ProLogic panel and Hayward has (at least) two versions of the manual with directly opposite instructions on wiring. Rev.H says wire through relay and Rev.J says wire directly to breaker. The pump manual shows the communication wiring from the VSP A/B/COM back to the panel terminals 2/3/4. Rev.J is the manual that came with my panel 5 years ago.
