Controller 30/Dual Controller Wiring Diagrams

Below you will find wiring diagrams for the Controller 30 and Dual Controller. Note that while the Controller 30 and Dual Controller look physically identical, the wiring and programming are different. The Controller 30 cannot be used with an AirLynk/BMS, whereas a Dual Controller must be used with AirLynk, which is the only product with bacnet/modbus/BMS capability. Additionally, the Dual Controller is wired one of two ways depending on your BMS (Building Management System) configuration.

*If Bacnet IP is used, use Controller A (Modbus RTU, RS485 Port). If Bacnet MSTP is used, use Controller B (Modbus TCP/IP, Lan A ethernet). Do not use the LAN B ethernet port.
