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 self-
contained 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.

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.
