regarding adding a pump to be controlled by STC ,
the pump has 2 wires in the power lead, positive and negative or positive and ground?
where does wire connect to on the stc circuit board? do you need to install a resistor or a capacitor as well when wiring it in?if you wire the positive wire...
How do use several firmware on the same unit ? say , 2 sensor, comm, wifi, one vessel, what if you wanted one vessel with comm and wifi? what if you wanted one vessel and 2 sensor?
