Johnson Controls M4-CVM03050 Installation Manual

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. 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 Metasys
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
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.
The CVM controllers can be used as functional
replacements for legacy N2 controllers. The N2-
capable MS/TP equipment controller models
provide a cost-effective upgrade and modernization
path for customers with existing N2 controllers.
For installation and commissioning support,
and tips for efficient and safe replacement,
refer to the Modernization Guide for Legacy N2
Controllers (LIT-12012005) and the controller-
specific documentation. For information about
mapping N2 Objects in controllers with switchable
communications protocols, refer to the N2
Compatibility Options chapter of the Controller Tool
Help (LIT-12011147).
To configure CVM controllers to communicate using
the N2 communications protocol, see
N2 communications.
The CVM controller can also be installed in a
wireless application using a ZFR/ZFR ProWireless
M4-CVM03050 VAV Controllers Installation
system network.

Compliance
United States
This equipment has been tested and found to
comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when this equipment
is operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications.
Operation of this equipment in a residential area
may cause harmful interference, in which case the
users will be required to correct the interference at
their own expense.
Canada
This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-
Causing Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte
toutes les exigences du Règlement sur le matériel
brouilleur du Canada.
Installation
Observe the following guidelines when installing a
CVM controller:
• To minimize vibration and shock damage to the
controller, transport the controller in the original
container.
• Verify that all parts shipped with the controller.
• Do not drop the controller or subject it to physical
shock.
