Johnson Controls F4-CVM03050 - User Manual

F4-CVM VAV Terminal Equipment
Controllers Installation Instructions
Application
The CVM03050 equipment controllers are designed for variable air volume (VAV) box applications.
CVM03050 controllers operate on an RS-485 BACnet
®
MS/TP bus as BACnet Advanced Application
Controllers (B-AACs) and integrate into Johnson Controls
®
and third-party BACnet systems.
CVM03050 controllers feature an integral damper actuator, a digital Differential Pressure
Transmitter (DPT) sensor, and a 32-bit microprocessor. The CVM03050-0P model features an
integral potentiometer to sense actual VAV box damper position. These controllers also include an
integral real-time clock, which enables the controllers to monitor and control schedules, calendars,
and trends, and operate for extended periods of time as stand-alone controllers when offline
from the Facility Explorer
®
system network. These controllers connect easily to the wired and
wireless network sensors for zone and discharge air temperature sensing. Their small package
size facilitates quick field installation and efficient use of space without compromising control
performance.

Communications protocols
The CVM03050 controllers can communicate using BACnet MS/TP, N2, or wireless Zigbee
®
. By
default, the CVM controllers communicate using the BACnet MS/TP protocol. The BACnet protocol
is a standard for ANSI, ASHRAE, and the International Standards Organization (ISO) for building
controls.
