[Proteus]

So I picked up a couple new titanium heaters.

These have external sensors and controller. Just wondering if I should use the same as my old ehiem tgat were hooked up to neptune controller. I'm just not sure if the digital controller on heater would be affected when the Neptune kills the power to them
