PCV16 and PCV18 series controllers are programmable digital controllers tailored for VAV applications that can switch between MS/TP and N2 Communications protocols. When they are used as MS/TP devices, they communicate through the BACnet® MS/TP protocol. In N2 mode, they can be used as replacements for legacy Johnson Controls® controllers.
The PCV controllers' small package size facilitates quick field installation and efficient use of space, while not compromising high-tech control performance. These controllers easily adapt NS Series Network Sensors for zone and discharge air temperature sensing.
The PCV18 models are designed to be functional replacements for the VMA14xx Series Variable Air Volume Modular Assembly Controllers. They contain a sensor bus port and accessories well suited for replacing VMA14xx Controllers.
The PCV1626 Controller is shipped with an actuator but without a differential pressure transducer (DPT), making the controller well suited for commercial zoning applications or for pressure-dependent VAV box applications where no DPT is required. The PCV1656 controller is shipped without a differential pressure transducer but with an integrated actuator and ball valve linkage. This controller is for use on the Johnson Controls VG-1000 1/2 to 1 inch valves and needs to be used primarily as a replacement for the assembly of the VG-1000 Series Smart Valve product. The smart valve product line is ideal for chilled beam applications. The PCV1628 includes a DPT but does not have an actuator. Without an actuator, this controller is well suited for controlling large VAV boxes that require more than 4 N•m of torque.
These features make the PCV controllers the product of choice for VAV systems. The wide variety of network sensor models provides options for measuring and displaying zone temperature, occupancy detection, duct temperature, zone humidity and dewpoint determination, carbon dioxide (CO2) level, setpoint adjustments, VAV box fan speed control, and discharge air temperatures.
