2009 AHR Expo Innovation Awards - Honorable Mention for the Reliable Controls SMART-Space Controller
SMART-Space Controller SMART-Space Controller Header
The SMART-Space Controller™ (SSC) is a compact and economical BACnet® controller. The SSC is designed for small point-count, standalone or distributed network applications supporting up to 200 SSCs per network. Standard features include up to 4 outputs and 3 inputs, a dedicated temperature sensor, and can accomodate any combination of optional occupancy sensor, humidity sensor, or real-time clock.

The standard SSC model has 2 universal inputs and 2 outputs jumper selectable to be either universal or TRIAC. The package model (SSCP) and enhanced model (SSCE) provide an additional universal input and additional TRIAC outputs.
