I recently acquired a 1993 Whitfield WP2 Advantage insert with a serial number in the 64xxx range. I noticed there is a service manual for it. I suspect the service manual has the schematic for how the unit is wired. Does anyone know if it also includes a schematic for the controller? From online photos the WP2 Advantage insert may have had more than one controller. Below is a photo of the controller for this unit.
