Product Overview

The VTR8300 Fan Coil Controller offers a new cost-effective solution for upgrading line-voltage fan coil unit
thermostats. The VTR8300 terminal Equipment Fan Coil Unit Controllers are available as BACnet
wireless ZigBee Pro networked models.

No previous building automation training is required for installation and commissioning process, and
installation can be completed in approximately fifteen minutes.
The SC3000 Series Line Voltage Switching Transformer Relay Pack Controllers are designed for silent control
of typical high voltage fan coil device loads (90 - 277 VAC multi-voltages). It uses advanced microprocessor-
based circuitry with a built-in transformer that eliminates all typical required peripheral components when
automating a Fan Coil unit with traditional building automation systems.
The SC3000 Series Line Voltage Switching Transformer Relay Pack(s) operate as slave unit(s) under the
control of a single master VTR83XX Terminal Equipment Controller.
A single VTR83XX Terminal Equipment Controller can control up to 10 x SC3000 Series Relay Packs as they
are line-powered units.
The unit locally contains all relay outputs for fan switching and valve control, and models are also available
for extra monitoring/control inputs of the Fan Coil Units.
