• Fully scalable zoning control system meets the requirements of small and large zoning control systems

• BACnet MS/TP communication provides compatibility with a proven communication network

• True stand-alone zoning control system offers additional application flexibility

• Backlit Display offers real-time control status of the environment in easy-to-read, English plain text messages with constant backlight that brightens during user interaction

• Simplified setpoint adjustment enables the user to change the setpoint by simply pressing the UP/DOWN arrow keys

• Configurable binary inputs provide additional inputs for advanced functions such as remote night setback, service or filter alarms, motion detector, and window status

• Over 20 configurable parameters enable the zoning control system to adapt to applications with varying requirements, allowing installer parameter access without opening the controller cover
