This system does not include a remote control.
The remote control panel is not required, the system will function fine without it. Think of it as your remote control for your television. It is nice to have in scenarios where the membrane is hard to access.
BUYER BEWARE of Chinese fiberglass pressure vessels, typically white in color, cannot handle hydraulic shocks caused by air sucked in during heavy seas. They are known to fracture and burst. The blue Epoxy resin vessel seen in the pictures is what we use. Tested to 6000 psi burst pressure. The 4 external rods act as springs and combined with our spring loaded automatic pressure regulator will absorb hydraulic shocks that can crack conventional fiberglass vessels that can lead to premature failure of the membrane.
