The System 2000 GEN II is a commercial modulating Auto Changeover zoning system that controls a single HVAC unit and supports 2 - 17 modulating zones. The control panel is Universal, supporting Gas/Electric or Heat Pump applications with two cooling stages and three stages of Heat.

The GEN II system does not require a computer to set up or operate.

Three-wire fully modulating zone dampers with elliptical dampers that track airflow linearly are controlled by the Zonex thermostat (ModStat).

Sophisticated integrated software allows for a wide range of system control and changeover strategies, allowing the contractor to tailor the GEN II system to your specific application.

Additional features include LED status indication of all system functions, digital LAT display, fully adjustable capacity control with onboard limit settings, and optional staging strategies. Night setback operation is standard with selectable 2-hour override at each stat, along with a unique feature to remotely lock thermostats in the system. This vote based system also provides priority weighting on a zone-by-zone basis, allowing the contractor to prioritize each thermosat with 1, 2, or 3 votes.

The system provides the installing contractor with a simple startup diagnostic to minimize wiring errors and to speed installation.

Gen II is recognized as the industry's easiest zone control system to install and wire. Modulating dampers operate over an unshielded two-wire data link, along with two 24V power wires all daisy chained from stat to stat with no home run wiring required.
