[Hot Springs Grandee Subpanel question]

I ma trying to connect my Grandee with the 76858 50/60 heater relay board to a 2 wire 230volt system using a 20 and 30 GFCI. This does not have the white 110 neutral wire, only a neutral and a 230 volt hot. I am looking for the proper connection. I believe it will be found on the install sheet for the 76858 board. Thanks!

[Power/Ready blinking, not heating, Hot Springs 2010 Sovereign II with new IQ2020 Eagle control board.]

I am trying to connect up a 2009 Grandee with a 76858 heater relay board and an IQ2020 to a 2 wire 230 volt supply. One leg of the 230 is hot, the other is neutral. No 110v circuit. I would like to use 2 GFCI breakers, one for the heater side and one for the pumps. Anybody have a diagram from the board for this setup from the package insert? I found one for a 5 connector board from the package insert but not for the 7 connector system.
