Chapter 2
General wiring information
This chapter provides specifications and general information about wir-
ing the Tracer ZN511 zone controller. The controller requires wiring for:
• Input/output terminals
• AC power to the controller
• Communication-link wiring, if the controller is to communicate with a
building automation system (BAS)
Input/output terminal wiring
All input/output terminal wiring for the Tracer ZN511 zone controller is
application specific and dependant on the configuration of the controller.
Input/output terminal wiring must meet the following requirements:
• All wiring must comply with the National Electrical Code and local
codes.
• Use only 18 AWG, twisted-pair wire with stranded, tinned-copper
conductors. (Shielded wire is recommended.)
• Binary input and output wiring must not exceed 1000 ft (100 m).
• Analog input wiring must not exceed 300 ft (100 m).
• Do not run input/output wires in the same wire bundle with any ac
power wires.
For application-specific wiring information and diagrams, see Chapter 4,
“Applications for the heat pump configuration”, and Chapter 6, “Applica-
tions for the 1 heat/1 cool configuration”.
