VT8650 Rooftop Unit, Heat Pump, and Indoor Air Quality Room Controller
The VT8650 room controllers are both application-specific and programmable. This enables the modification of pre-configured control sequences or scripting to modify existing behavior. The VT8650 room controllers provide exception control of staged heating and cooling equipment such as packaged roof-top units. Their configurable control sequences, economizer, and scheduler functionalities deliver all the flexibility necessary for optimal indoor air quality applications.
