Application Guide 2 VTR8300 Fan Coil Controller Overview 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.
