Traditionally, upgrading an existing fan coil unit controlled by a line- voltage thermostat was considered as an expensive option with poor return on investment. Extra components to upgrade, such as relays, transformers, controllers, sensors and network wiring, caused proposals to be quickly dismissed. This left the fan coil units to be controlled by stand-alone thermostats with no capacity for energy optimization. Features available such as, set point limitations, advanced occupancy routines and other functions offered by central automation systems were simply not an option. Now, a new cost effective solution is available for upgrading line-voltage fan coil unit thermostats! The new Viconics fan coil unit solution requires installation of only two components: The VTR7300 terminal equipment controller and the VC3000 relay pack. This allows reuse of existing line- voltage wiring between the fan coil unit and temperature controller thereby reducing overall costs, labor and installation time for both retrofit and new construction control projects. The VC3000 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 VTR7300 wall mounted controller features a digital display and built-in commissioning and configuration utility, temperature sensor and optional humidity and passive infra red occupancy sensor (PIR). No previous building automation training is required for the easy installation and commissioning process, which can be completed in about fifteen minutes, reducing overall installation time and providing increased savings. The VTR7300 terminal equipment fan coil unit controllers are available as stand-alone, Network Ready, BACnet® MS/TP or wireless ZigBee® networked models. The stand-alone Network Ready models can be easily retrofitted on-site with our network communication modules for BACnet® MS/TP or wireless ZigBee® protocols. The wireless ZigBee® communication adapter allows for data exchange and connectivity into the Niagara AX™ software framework and development environment. The Viconics stand-alone network-ready controllers allow for easy expandability which ensures longevity and the possibility for future system upgrades.
