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 outside 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
CO2sensor, and either a 20k outdoor air temperature sensor
or Sylk Bus sensors for measuring outside 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.
CO2Sensor (optional)
A CO2sensor (non-communicating or non-Sylk Bus) can be
added for Demand Control Ventilation (DCV).

Economizer Module Location and
Mounting
IMPORTANT
Avoid mounting in areas where acid fumes or other
deteriorating vapors can attack the metal parts of the
module’s circuit board, or in areas where escaping
gas or other explosive vapors are present.
IMPORTANT
The module must be mounted in a position that allows
clearance for wiring, servicing, and removal.
Mount the Economizer module on any convenient interior
location using the two mounting holes provided on the
enclosure using #6 or #8 screws (screws are not provided and
must be obtained separately). Use the dimensions in Fig. 1 on
page 2 as a guide.
The Economizer module may be mounted in any orientation.
However, mounting in the orientation shown in Fig. 1 on page 2
permits proper viewing of the LCD display and use of the
keypad.
Sensor Location and Mounting
The JADE™ Economizer W7220 uses digital sensors for
control. The MATaand OATbsensors are 20k NTC sensors. A
MAT sensor is required for all applications and is mounted in
the mixed air section of a rooftop unit either directly to the
sheet metal using self tapping sheet metal screws or in the air
stream using the duct mounting kit.
Optional OAT, RATcand DATdSylkbus sensors communicate
with the W7220 on the two-wire communication bus and can
either be wired using a two pin header or using a side
connector. Each Sylkbus sensor includes a two pin Euro
connector with the packaging. The SKU number of the Sylkbus
sensor is C7400S. All OAT, RAT and DAT sensors are the
same SKU number. The sensor is set for the appropriate type
of sensing using the three position DIP switch located on the
sensor. OAT position is OFF, OFF, OFF; RAT is ON, OFF, OFF
and DAT is OFF, ON, OFF. During installation the sensors are
set for the usage desired. See “Sylk Bus Sensor Wiring” on
page 6 for DIP switch details.
Once installed, a sensor can be changed to a different
application by simply changing the DIP switch setting.

Sensor Mounting
The sensors can be mounted directly on to the sheet metal of
unit or can be mounted in the air stream using the duct
mounting kit.
The kit contains a rod to hold the sensor in the duct, a flange to
secure the sensor rod to the duct wall and fill the hole and a
gasket to prevent air from leaking through the duct wall. See
Fig. 2.
The rod has slots for threading the wire to prevent loose or
hanging wire in the duct and can be adjusted for 6 or 12 inch
length. The flange has extended relief for ease of mounting.
See 3.
Fig. 2. Duct Mounting Kit (Part Nbr. 50053060-001).
Fig. 3. Duct Mounting Adjustments.
WIRING
All wiring must comply with applicable electrical codes and
ordinances, or as specified on installation wiring diagrams.
Module wiring in the field is terminated to the four screw
terminal blocks located on the left and right sides.
Module wiring at the OEM factory is terminated via the header
pin terminals located on the left and right sides. The header
terminal pins and the terminal blocks have common
terminations for the appropriate input or output. The part
number of the mating female connector for OEMs is 0035977.
The remainder of this section describes the wiring for the
JADE™ Economizer module, W7220A.
WARNING

SETUP AND CONFIGURATION
Before being placed into service, the JADE™ Economizer
module must be setup and configured for the installed system.
IMPORTANT
During setup, the Economizer module is live at all
times.
The setup process uses a hierarchical menu structure that is
easy to use. You press the and arrow buttons to move
forward and backward through the menus and press the ↵
button to select and confirm setup item changes.
Time-out and Screensaver
When no buttons have been pressed for 10 minutes, the LCD
displays a screen saver, which cycles through the Status items.
Each Status items displays in turn and cycles to the next item
after 5 seconds:
Enthalpy Settings
When the OA temperature, enthalpy and dew point are below
the respective setpoints, the outside air can be used for
economizing. Fig. 12 shows the new single enthalpy
boundaries in the W7220. There are 5 boundaries (setpoints
ES1 through ES5), which are defined by dry bulb temperature,
enthalpy and dew point.
Refer to Table 6 for the ENTH CURVE setpoint values.
Fig. 12. Single Enthalpy curve and boundaries.
To use enthalpy the W7220 must have a C7400S Sylkbus
sensor for OA. The W7220 calculates the enthalpy and dew
point using the OA temperature and humidity input from the OA
sensor. When the OA temperature, OA humidity and OA dew
point are all below the selected boundary, the economizer sets
the economizing mode to YES, economizing is available.
When all of the OA conditions are above the selected
boundary, the conditions are not good to economize and the
mode is set to NO.
Fig. 12 shows the 5 current boundaries. There is also a high
limit boundary for differential enthalpy. The high limit boundary
is ES1 when there are no stages of mechanical cooling
energized and HL when a compressor stage is energized.
Table 6 provides the values for each boundary limit.
Economizer Setup and Configuration
To setup and configure the Economizer module, use the
System Setup menu, the Advanced Setup menu (if necessary),
and the Setpoints menu. Refer to Table 7.
Setup and configure the module in the following order:
1. Enter the System Setup parameters.
2. If needed, enter the Advanced Setup parameters.
3. Enter the Setpoint settings.
