I have an Aqualink RS8 controller with some wires on a 4 pin connector in top left corner, Green (ground), Pool (Yellow), Spa [Blue], Hot (Red), and on another line Common [white] .
where do these connect to the Hayward heater H400FDN 3 wire remote marked (Spa, COM, Pool)
I tried connection Spa to Spa, Common to white, and Pool to Pool, but that did not work.
Should I connect the line with electricity (hot) to the COM ?
