The FX-PCG products are programmable controllers that can be switched between BACnet MS/TP and N2 Communications protocols. When they are used as BACnet MS/TP devices, they are a BACnet Application Specific Controller [B-ASC] with integral MS/TP communications. In N2 mode, they can be used to modernize sites with legacy Johnson Controls controllers. These controllers run pre-engineered and user-programmed applications and provide the inputs and outputs required to monitor and control a wide variety of HVAC equipment. A full range of FX-PCG models combined with the FX-PCX model can be applied to a wide variety of building applications ranging from simple fan coil or heat pump control to advanced central plant management. All FX-PCG Series Controllers configured for BACnet support wireless communications using the FX-ZFR or FX-ZFR Pro System accessories.
