Page 6: Theory Of Operation
HEORY OF PERATION The VZ7656 series uses a Viconics proprietary adaptive logic algorithm to control the space temperature. This algorithm controls the heating and or air conditioning system to minimize overshoot while still providing comfort. It provides exceptional accuracy due to its unique PI time proportioning control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based on/off thermostats. - Page 7 Easy configuration without using any special software or additional tools. • Can be used as stand-alone or with BACnet™ MS-TP supervision controller for • monitoring purposed. Truly scalable in terms of supported number of zones and RTU units. • 028-0324-02_LIT-VZ7656F_B-E01_EN www.viconics.com October 2019...

Page 8: Bacnet System Overview
YSTEM VERVIEW Viconics VZ7260x5x00B Zone controllers are used in conjunction with the VZ7656F1000B roof top controllers. Combined, they are designed for operating typical; single or multistage RTU’s and their associated local zones. For example, a typical job layout system may feature 3 RTU controllers and a total of 31 zones. This would bring to total number of nodes (individual Com addresses) to 34. -
