AHU controllers supported a Zone Bus for connecting M100C Series networked actuators. FAC and CGM controllers do not support the Zone Bus, and accordingly do not support these devices. When using an FAC and CGM controller to replace an AHU controller that uses an M100C zone bus actuator, you must replace the actuator with a non-networked actuator. For dampers, use the M9100/M9200 Series. For valves, use the VA7800/VA-7150 Series.
To control the new actuator, use the available analog output or configurable output interfaces on the FAC and CGM controller, or, if none are available, add an M4-XPM or IOM Expansion I/O Module.
