4. Locate the coin cell Battery Holder attached to the CB (Circuit Board).
5. Slide a fresh, new coin cell Battery (CR2032 or equivalent) into the Battery Holder. NOTE: the + side of the Battery should be contacting the Battery Holder and the -side should be contacting the CB.

7. Make your TDS selection on the DIP Switch. See DIP Switch chart.
8. Replace the Knob by holding it over the Valve Base and aligning the vertical ridge inside the Knob with the Valve Lever.

12. To make sure the Knob is installed properly, rotate it fully to the left ( clockwise from top view) and check to see the LED Indicator has stopped flashing.
13. Rotate the Knob to the right and check to see the LED Indicator begins to flash Blue (green), then rotate the Knob back to the left.
