WALL MOUNT POTENTIOMETER CONTROL
Potentiometer and wall plate are provided with this option. It is factory hard wired and tested.
Signal is 0-10VDC. Potentiometer is 0-10K Ohms.
To relocate the potentiometer cut the wires leaving enough lead to make new connections. Run 3 conductor wire rated for the
