Room Controller SER7300 Line Voltage Fan Coil Controller with SC3000 Relay Pack The SER7300 fan coil unit solution requires installation of only two components, the SER7300 terminal equipment controller and the SC3000 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.2 Schneider Electric | SDS-SER7300SC3000-EN.A4.08.2015.v2 www.schneider-electric.com/buildings August 2015 The SER7300 fan coil unit room controllers are available as stand-alone, Network Ready, BACnet® MS/TP or wireless ZigBee® Pro 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® Pro protocols. Introduction Now, a new cost-effective solution is available for upgrading line-voltage fan coil unit thermostats. The SER7300 fan coil unit solution requires installation of only two components; the SER7300 room controller and the SC3000 relay pack. This allows reuse of existing line-voltage wiring between the fan coil unit and temperature controller, thereby reducing overall costs, labour, and installation time for both retrofit and new construction control projects. Fan coil terminal equipment controlles with relay packs Upgrading an existing fan coil unit controlled by a line-voltage thermostat is 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 resulted in fan coil units being controlled by stand-alone thermostats with no capacity for energy optimisation. As such, features available such as set point limitations, advanced occupancy routines, and other functions offered by central iBMS systems were simply not an option. The SC3000 relay pack features an onboard 90 - 277Vac power supply and line-voltage relays, which directly drives fractional horsepower fan motors and valves. This eliminates the need to install and wire costly pilot relays and transformers. The SER7300 wall mounted controller features a digital display and built-in commissioning and configuration utility, temperature sensor, and optional humidity and Passive Infrared (PIR) occupancy sensor. No previous building management training is required for the easy installation and commissioning process, which can be completed in fifteen minutes, reducing overall installation time and providing increased savings. The SER7300 terminal equipment fan coil unit controllers are available as stand-alone, network ready, BACnet ® MS/TP or wireless ZigBee ® Pro 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 Pro protocols. The stand-alone network-ready controllers allow for easy expandability, which ensures longevity and the possibility for future system upgrades.
