VT8300 Series CONFIGURABLE BI/UI UNIVERSAL INPUTS OVERVIEW 4. Universal input #16 can be configured for the following binary functions: 1. (None): No function will be associated with the input 2. (Rem NSB): remote NSB timer clock input. The scheduling will now be set as per the binary input. It provides low cost setback operation via a dry contact. Contact opened = No alarm Contact closed = Alarm displayed 5. Contact opened = Occupied Contact closed = Unoccupied 3. 4.

Installation Guide 13 VT8300 Series Appendix A: Terminal Correspondance The terminals of a VT8300 are identified differently and have a wider range of possible functions compared to those of any of the VT7000 series Room Controllers. Nonetheless, there is a direct correspondance of functions between the terminals of the VT7000 series and the VT8300 series. Consult the table below to verify the appropriate terminal when replacing a VT7000 Room Controller with a VT8300 Room Controller.
