SER8300 ROOM CONTROLLER AND SC3000 AND RELAY PACKS

This new cost-effective solution for upgrading line-voltage fan coil unit thermostats requires only two components, the
SER8300 Room Controller and the SC3000 Relay Pack. This solution allows existing line voltage wiring between the fan coil
unit and Room Controller to be re-used, thereby reducing overall costs and installation time.

The SC3000 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 Relay Pack is not required for the SE8300 Series models.

SE8300 ROOM CONTROLLERS

This new cost-effective solution for upgrading low-voltage fan coil unit thermostats requires only the SE8300 Terminal
Equipment Controller.

The SE8300 Terminal Equipment Controller can also be used along with a SC1300 or SC2300 Relay Pack for mixed-voltage
solutions, when control of both line-voltage and low-voltage end devices is required.
