Viconics VT8650 Programmable Thermostat

Smart energy management has never been easier than with the VT8650 Series Room Temperature and Indoor Air Quality (IAQ)Controller. Designed for new construction and retrofit projects, the temperature and IAC controllers dramatically decrease project delivery costs by reducing installation, configuration, and commissioning time. No complex software or tools are required to customize functionality in order to meet your application requirements. The Room Controllers provide all the advanced features and monitoring functions required by modern building automation systems in a simple compact enclosure. The VT8650 Room Controllers, part of the VT8000 family, are both application-specific AND programmable. This enables the modification of pre-configured control sequences, or the creation of entirely new control sequences for HVAC, lighting, and other applications. The VT8650 Room Controllers provide exceptional control of staged heating and cooling equipment such as packaged roof-top units in addition to modulating heating and cooling. Their configurable control sequences, economizer, and scheduler functionalities deliver all the flexibility necessary for optimal indoor air quality applications.

Note: The outside air damper can be controlled based on CO2 or airflow demand.
