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
enthalpy 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 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
2
sensor, and either a 20k outdoor air
temperature sensor 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. See page 2 for
details.
CO
2
Sensor (optional)
A CO
2
sensor can be added for Demand Control
Ventilation (DCV). Either an analog (2-10 Vdc) or a wall-
mount Sylk bus TR40 CO
2
sensor can be used with the
Jade economizer.
