tronic controller.
NOTE: It is recommended that the wire colors illustrated in
Appendix A be used when installing the switch panels.
This will ensure installation consistency, differentiate
between the separate switches, and assist service per-
sonnel with troubleshooting.
Reference Appendix B for proper wire-gauge sizing.
