Comm5 is Trane’s implementation of LonTalk®. Trane has updated its recommendations for Comm5 wiring and topology. These recommendations are different than originally published Comm5 installation practices. The following information summarizes the wiring and topology recommendations:
- Use 22 AWG Level 4 unshielded communication wires for most Comm5 installations.
- Use shielded Level 4 wire for all communication wiring on the VariTrac central control panel (CCP). See “Specifications for Level 4-compliant cables” on page 11.
- Limit Comm5 links to 4,500 ft and 60 devices maximum (without a repeater).
- Use the following termination resistors on all links:
- 105 Ω at each end for Level 4 wire
- 82 Ω at each end for Trane “purple” wire
- Use daisy chain topology.
- Limit zone sensor communication stubs to 8 per link, 50 ft each maximum.
- Use one repeater for an additional 4,500 ft, 60 devices, and 8 communication stubs.
