How do the buttons on the multi-button interface (MBI) station work? Does each button control a different zone?
The MBI station uses button pairs for output control. Every 2 buttons are paired and function together, with one button being 'on' and the other being 'off'. You can also think of the button pair as either end of an Echoflex switch paddle. The button with the illuminated light bulb icon is the 'on' side and the button with the de-illuminated light bulb icon is the 'off side'.
