Wiring the Probe to the Controller 10
9. WIRING THE PROBE TO THE CONTROLLER
1. With the controller disconnected from power, run the probe cable through the conduit opening.
2. Connect the probe leads to the removable terminal connector marked PROBE. Follow the lead markings
(+) positive / (–) negative to ensure correct wiring position for the output leads.
3. Carefully put the wired terminal connector into place on the board.
