VTR8350 Line-Voltage Fan Coil Controller with VC3000 Relay Pack for Retrofit Applications 


This two-component retrofit option consists of the VTR8350 terminal equipment controller and the VC3000 Relay Pack. Together, they provide an easy solution for retrofitting fan coil unit thermostats without requiring other components such as relays, transformers, controllers, sensors, and network wiring to be upgraded. Existing line voltage wiring between the fan coil unit and temperature Controller can be reused further minimizing overall labor and installation costs for both retrofit and new construction control projects. Additional flexibility and energy savings can be achieved with optional wireless door, window, motion and water leak sensors. An elegantly simple casing combines with configurable screen colors to match decor.
