Product Overview

The VT76xx PI controller family is specifically designed for single stage and multi-stage control of heating/cooling equipment such as rooftop and selfcontained units. The product features an intuitive, menu-driven, back-lit LCD display, which walks users through the programming steps, making the process extremely simple. Accurate temperature control is achieved due to the product’s PI time proportional control algorithm, which virtually eliminates temperature offset, associated with traditional, differential-based controllers.

The 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 Unoccupied 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 controllers can be ordered with or without a factory installed PIR cover.

The additional following documentation is available on www.viconics.com

-Detailed information on the controller (VT76xxX5x00x), is available on document: LIT-VT7600-PIR-E00.doc

-Detailed information on the controller (VT76x7X5x00x), is available on document: LIT-VT76x7-PIR-E00.doc

-PIR application information and examples, are available on document: APP-VT76-PIR-Guide-Exx

Product Description:

The VT76xx series BACnet communicating controller have been specifically designed for RTU and heatpump applications to be monitored on a BACnet MS-TP® network.

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).

Application Service	Designation
Data Sharing – Read Property - B	DS-RP-B

Data Sharing – Read Property Multiple - B	DS-RPM-B

Data Sharing – Write Property - B	DS-WP-B

Device Management - Device Communication Control - B	DM-DCC-B

Device Management – Dynamic Device Binding - B	DM-DDB-B

Device Management – Dynamic Object Binding - B	DM-DOB-B

Note 1: The controller does not support segmented requests or responses.

Note 2: Time synchronization can be made through a network even if the controller does not support the full date. Therefore, the device cannot claim conformance to the DeviceManagement – TimeSynchronization - B (DM-TS-B) service. The device object does not have the Local_Time or Local_Date properties.
