VZ7260 Product Overview
The Viconics VZ7260 PI controller family is specifically designed for local
pressure dependent VAV zone control within Viconics Zoning System
product family.
The product features a backlit LCD display with dedicated function menu
buttons for simple user operation. Accurate temperature control is achieved
due to the product’s PI proportional control algorithm, which virtually
eliminates temperature offset associated with traditional, differential-based
controllers.
The controllers are used in conjunction with the Viconics VZ76561000B
Roof Top Controller for total system operation of each zones and the RTU.
A local BACnet RS485 MS-TP communication bus between all devices insures proper communication and data
exchange of all required information between the Zone controllers and RTU controller. They can be seamlessly
integrated into any 3rd party BACnet supervision system.
The Zone controllers are also compatible with the new Viconics PIR cover accessories. Controllers equipped with a
PIR cover provide advanced active occupancy logic, which will automatically switch occupancy levels from
occupied to stand-by as required by local activity being present or not. This advanced occupancy functionality
provides advantageous energy savings during occupied hours without sacrificing occupant comfort. All Zone
controllers can be ordered with or without a factory installed PIR cover (see ordering notes below).
VZ7656 Product Overview
The Viconics VZ7656 controller is specifically designed for RTU control of the Viconics
Zoning System product family.
The RTU controller is designed for single stage or multi-stage control of heating and
cooling equipment such as rooftop and self-contained units used in zoning systems.
The product features a backlit LCD display with dedicated function menu buttons for
simple user operation. Accurate temperature control is achieved due to the product’s PI
proportional control algorithm, which virtually eliminates temperature offset associated
with traditional, differential-based controllers.
The controller also contains extra digital inputs, which can be set by the user to monitor
filter status or used as a general purpose service indicator. All models contain a SPST
auxiliary switch, which can be used to control lighting or disable the RTU economizer
function during unoccupied periods. It also features a discharge air sensor input.
Proportional static pressure logic (input and output) has been integrated onto the
controller to provide a complete single packaged unit for most small to medium size jobs.
The controllers are used in conjunction with the Viconics VZ7260 Zone controllers for total system operation of
each zones and the RTU.
A local BACnet RS485 MS-TP communication bus between all devices insures proper communication and data
exchange of all required information between the Zone controllers and the RTU controllers. They can be
seamlessly integrated into any 3rd party BACnet supervision system.

BACnet System Overview
Viconics VZ7260 zone controllers are used in conjunction with the VZ7656 roof top controllers. Combined, they
are designed for operate typical single or multistage RTUs and their associated local zones.
Typical BACnet zoning system installation
Please refer to the following Viconics documents for detailed information and design guidelines for the BACnet
zoning system version:
As an example, a typical job layout system may feature three RTU controllers with thirty one total zones. This
would bring to total number of nodes (individual Com addresses) to thirty four. RTU one would have ten zones
under its command, RTU two would have ten zones under its command and RTU three would have eleven
zones under its command.

Product Description:
The Viconics VZ7260 PI controller family is specifically designed for local pressure dependent VAV zone control
within Viconics Zoning System product family.
The controllers are used in conjunction with the Viconics VZ76561000B Roof Top Controller for total system
operation of each zones and the RTU.
VZ7260 Supported BACnet Services
The BACnet communicating controller meets all requirements for designation as an Application Specific Controller
(B-ASC). The BACnet controller series supports the following BACnet Interoperability Building Blocks (BIBBs).
The following BACnet Interoperability Building Blocks supported are used ONLY with the VZ76561000B Roof Top
Controller for system operation. The following BiBBS are NOT listed under the “protocol service supported” device
attribute. As such, the VZ7260 application cannot use these services to communicate with “other” third party
devices (see Annex K in BACnet 2004):
Note: The controller does not support segmented requests or responses.
