Marvair Exterior Wall Mounted Cooling Unit

Marvair VT8650 Overview 

Introduction 

Smart energy management has never been easier than with the VT8650 Room 

Controllers for Rooftop Units, Heat Pump and Indoor air Quality applications. 

Designed for new construction and retrofit projects, the Room Controllers 

dramatically decrease project delivery costs by reducing installation, configuration 

and commissioning time. No complex software or tools are required to 

customize functionality to meet your applications requirements. The Room Controllers 

provide all the advanced features and monitoring functions required by modern building 

automation systems in a simple compact enclosure. 

Application Specific and Programmable 

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. 

Their configurable control sequences, economizer and scheduler functionalities 

deliver all the flexibility necessary for optimal indoor air quality applications. 

Touch Screen with Customizable User Experience The touch screen of the VT8650 

Room Controller offers a customizable user experience with selection of languages, 

temperature scales, buttons, and screen colors. Using the 8000 Uploader Tool, it 

also supports the upload of an image or logo that becomes the default standby 

screen of the device. Custom messages can also be displayed on-screen using 

BACnet® objects when the VT8650 Room Controller is integrated via a BACnet 

MS/TP, BACnet IP or Modbus RTU system
