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.

SER7300 and SC3000 Series Features
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 retrot 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,
AT A GLANCE
Custom design
• Suitable for commercial and hospitality
markets and systems
• Available as a stand-alone unit with
Network Ready functionality
• Available with ZigBee® Pro wireless mesh
network or BACnet® MS-TP communication
module
• Advanced occupancy functions for
commercial and lodging applications
• Configurable fan sequence operation
• On board configuration interface utility
Options and accessories
• PIR occupancy sensor
• Humidity sensor with on-board
dehumidification strategy functions
• Wireless door and window switches
communication
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 conguration 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 fteen 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
networked models. The stand-alone network ready models can be easily
retrotted 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.
