SYSTEM OVERVIEW
SYSTEM OVERVIEW
The
GEN II
is a commercial modulating zone control system controlling 2-17
nes per unit. The
GEN II
controller is designed for Auto Changeover, multi-stage Heat Pump
(2C/3H) and Gas Electric (2C/2H) applications.
The
GEN II
system uses the Zonex EzTouch,
which modulates and controls the “ST” series, 3-wire,
24-volt, power open / power close round and rectangular dampers.
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 on-board 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.
The system provides the installing contractor with a simple startup diagnostic to minimize wiring
errors and speed installation.

GEN II
is recognized as the Industry’s easiest commercial zone control system to install and wire. The
GEN II
system operates 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. Three wires from the stat to actuator
control a modulating damper in each zone.
The
GEN II
system does not require a computer to set up or operate.
