JADE™ Economizer Module
(MODEL W7220)

PRODUCT DESCRIPTION

The JADE™ Economizer System is an expandable
economizer control system, which includes a W7220
Economizer Module (controller) with an LCD and keypad. The
W7220 can be configured with optional sensors.
The W7220 Economizer Module can be used as a stand-
alone economizer module wired directly to a commercial set
back space thermostat and sensors to provide Outdoor Air
dry-bulb economizer control.
The W7220 Economizer Module can be connected to optional
Sylk Bus sensors for single or differential economizer control.
The W7220 Economizer Module provides power and
communications on the Sylk Bus for the Sylk Bus sensors.
The W7220 Economizer Module automatically detects
sensors by polling the Sylk Bus to determine which sensors
are present. If a sensor loses communications after it has
been detected, the W7220 Economizer indicates a device fail
error on its LCD.
System Components
The JADE™ Economizer System includes an Economizer
Module, 20k mixed air sensor, damper actuator, an optional
CO
sensor, and either a 20k outdoor air temperature sensor
2
or Sylk Bus sensors for measuring Outdoor Air and return air
enthalpy, temperature, and humidity.
Economizer Module
This is the core of the JADE™ Economizer System and
includes the user interface for the system. The W7220
Economizer Module provides the basic inputs and outputs to
provide simple economizer control. When used with the
optional Sylk Bus sensors, the Economizer Module provides
more advanced economizer functionality.
Sylk Bus Sensors (optional)
The Sylk Bus Sensor is a combination temperature and
humidity sensor which is powered by and communicates on
the Sylk Bus. Up to three sensors may be configured with the
JADE™ Economizer Module.
CO
Sensor (optional)
2
A CO
sensor (non-communicating or non-Sylk Bus) can be
2
added for Demand Control Ventilation (DCV).
