VTR8300 & Relay Pack
This new cost-effective solution for upgrading line-voltage fan coil unit thermostats requires only two components: the VTR8300 terminal
equipment controller and the SC3000 relay pack. This solution allows existing line voltage wiring between the fan coil unit and temperature
controller to be re-used, reducing overall costs and installation time. The SC3000 relay pack features an onboard universal voltage power
supply and line-voltage relays which directly drive fractional horsepower fan motors and valves. This eliminates the need to install and wire
costly pilot relays and transformers.
The VTR8300 Line Voltage Fan Coil Terminal Equipment Controller and SC3000 Relay Pack can be configured to handle a broad variety of
applications covering all the standard implementations necessary for controlling line-voltage HVAC systems.
In addition to controlling heating, cooling and fan activity, depending on the model the VTR8300 can handle wireless networking
and switches, passive infrared (PIR) occupancy detection using either onboard or remote sensors, and dehumidification control. The
applications described here cover all these features, and in combination with the VTR8300’s advanced scheduling and occupancy controls
can provide the functionality for any required line-voltage HVAC implementation.
