FX-PCV Programmable VAV Box Controllers

The FX-PCV controllers feature an integral digital pressure sensor, an integral damper actuator, and a 32-bit microprocessor. The controllers' small package size facilitates quick field installation and efficient use of space, while not compromising high-tech control performance. These features make the FX-PCV the product of choice for VAV box control. The wide variety of network sensor models provides options for measuring and displaying zone temperature, occupancy detection, duct temperature, zone humidity and dew point determination, carbon dioxide (CO2) level, setpoint adjustments, VAV box fan speed control, and discharge air temperatures. The FX-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 FX-PCV1656 controller is shipped without a DPT but with an integrated actuator and ball valve linkage. This controller is for use on the Johnson Controls VG-1000 1/2 - 1 inch valves and needs to be used primarily as a replacement for the FX-PCV assembly of the VG-1000 Series Smart Valve product. The smart valve product line is ideal for chilled beam applications. The FX-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.
