• Avoid touching exposed conductors and components leads with skin or clothing. For additional information about anticipated transmission delays or failures of the link, refer to NEMA ICS 1.1 (latest edition), Safety Guidelines for the Application, Installation and Maintenance of Solid State Control or its equivalent. 028-0323-02_LIT-VZ7656R&VZ7656H_W-E01_EN www.viconics.com September 2019...
Page 4 • Do not drop or crush the Room Controller, or allow it to come into contact with liquids. • Do not use a damaged device (such as one with a cracked screen). Failure to comply with these recommendations will result in damage to the unit and void the manufacturer’s warranty. 028-0323-02_LIT-VZ7656R&VZ7656H_W-E01_EN www.viconics.com September 2019...

Insert screws in mounting holes on each side of the base (fig. 2). Gently swing back the circuit board on the base and push on it until the tabs lock it. Strip each wire 1/4 inch from end. 028-0323-02_LIT-VZ7656R&VZ7656H_W-E01_EN www.viconics.com September 2019...
Page 6: Theory Of Operation
HEORY OF PERATION The VZ765 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 Locks out heat pump compressor operation when outside air temperature is below this value. Compressor/auxiliary interlock: • Adds flexibility by locking out heat pump operation during auxiliary heating, to prevent high pressure trip when the coil is downstream of the auxiliary heat source. 028-0323-02_LIT-VZ7656R&VZ7656H_W-E01_EN www.viconics.com September 2019...
Page 8: Wireless System Overview
IRELESS YSTEM VERVIEW Viconics VZ72605x00W Zone Controllers are used in conjunction with the VZ7656x1000W 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.
