DISPENSER CONTROL<br />
The Niagara board is present in T-line dispenser models. It is mounted to the right<br />
of the Gemini board with the P1 connector in the upper left (rotated 90º counterclockwise<br />
from the orientation shown in this diagram). P6 and P7 are WIDE serial<br />
communications ports with the dispenser user interface and the smart valve, respectively.<br />
The board is powered through P1 and detects when the FC (freezer<br />
compartment) door switch is closed—the unit will not dispense when the door is open.<br />
